Une conception cohérentedes offres de la Moyenne Tension à l'Ultra terminal

Toutes les offres Merlin Gerin sont conçues selondes règles de cohérence électrique, mécanique et de communication.Les produits expriment cette cohérence par le design d'ensemble et l'ergonomie commune.

Cohérence électrique :

Chaque produit respecte ou renforce les performances du système au niveau coordination : pouvoir de coupure, Icc, échauffements, … pour plus de sécurité, de continuité de service (sélectivité) ou d'optimisation économique (filiation). Les technologies de pointe utilisées dans the Guiding System de Merlin Gerin permettent d'atteindre des niveaux de performances élevées en filiation et sélectivité des appareils de protection, tenue électrodynamique des interrupteurs et répartiteurs de courant, dissipation thermique des appareils, répartiteurs et enveloppes.De même, la Compatibilité Electro-Magnétique (CEM) des produits entre eux est garantie.

La sélectivité assure la coordination entre les caractéristiques de fonctionnement de disjoncteurs placés en série. En cas de défaut en aval, seul le disjoncteur placé immédiatement en amont du défaut déclenche.

Cohérence mécanique :

Chaque produit adopte les standards dimensionnels qui facilitent et optimisent son utilisation au sein du système. Il partage les mêmes accessoires et auxiliaires et respecte les choix ergonomiques globaux (mode d'utilisation, mode opératoire, organe de réglage et de configuration, outillage, …) facilitant ainsi son installation et son exploitation au sein du système.

Raccordement direct de la canalisation Canalis KT sur le disjoncteur Masterpact 3200 A.

Cohérence communication :

Chaque produit respecte les choix globaux en terme de protocole de communication (Modbus, Ethernet, …) pour une intégration simplifiée dans les systèmes de gestion, supervision et contrôle.

Grâce à l’utilisation de technologies standard du Web, vous pouvez proposer à vos clients des tableaux Merlin Gerin intelligents, permettant un accès facile aux informations : suivi des courants, tensions, puissances, historiques des consommations, …

Des outils et services, pour une conception et mise en œuvre plus efficace de vos installations.

Remote trippingShunt Trip (SHT) or Under Voltage Release (UVR).

bbbb Shunt Trip (SHT)v this release trips the circuit breaker when the control voltage rises above 0.7 x Unv control signals can be of the impulse type (> 20 ms) or maintained.

b Under Voltage Release (UVR)v this release trips the circuit breaker when the control voltage drops below a tripping thresholdv tripping threshold between 0.35 and 0.7 times the rated voltagev circuit breaker closing is possible only if the voltage exceeds 0.85 times the rated voltagev circuit breaker tripping by an UVR release meets the requirements of standard IEC 60947-2.

bbbb OperationWhen the circuit breaker has been tripped by an UVR or SHT release, it must be reset locally:v UVR or SHT tripping takes priority over manual closingv in the presence of a standing trip order, closing of the contacts, even temporary, is not possible.

Installation guide Safety clearances and minimum distances 0

EasyPactWhen installing a circuit breaker, minimum distances (safety clearances) must be maintained between the device and panels, bars and other protection devices installed nearby. These distances, which depend on the ultimate breaking capacity, are defined by tests carried out in accordance with standard IEC 60947-2.If installation conformity is not checked by type tests, it is also necessary to:b use insulated bars for circuit-breaker connectionsb block off the busbars using insulating screens.For EasyPact breaker, terminal shields, inter-phase barriers or an insulation isolator are recommended and may be mandatory depending on the utilisation voltage and the type of installation.

Installation guide Current-limiting curves 0

The exceptional limiting capacity of the EasyPact range greatly reduces the forces created by fault currents in devices.The result is a major increase in breaking performance.

The Ics value, defined by IEC standard 60947-2, is guaranteed by tests comprising the following operations:b break three times consecutively a fault current equal from 25% to 100% of Icub check that the device continues to function normally:v it conducts the rated current without abnormal temperature risesv protection functions perform within the limits specified by the standardv suitability for isolation is not impaired.

Longer service life of electrical installationsCurrent-limiting circuit breakers greatly reduce the negative effects of short-circuits on installations.Thermal effectsLess temperature rise in conductors, therefore longer service life for cables.Mechanical effectsReduced electrodynamic forces, therefore less risk of electrical contacts or busbars being deformed or broken.Electromagnetic effectsLess disturbances for measuring devices located near electrical circuits.

Economy by means of cascadingCascading is a technique directly derived from current limiting. Circuit breakers with breaking capacities less than the prospective short-circuit current may be installed downstream of a limiting circuit breaker. The breaking capacity is reinforced by the limiting capacity of the upstream device.It follows that substantial savings can be made on downstream equipment and enclosures.

Current-limiting curvesThe current-limiting capacity of a circuit breaker is expressed by two curves which are a function of the prospective short-circuit current (the current which would flow if no protection devices were installed):b the actual peak current (limited current),b thermal stress (A2s), i.e. the energy dissipated by the short-circuit in a conductor with a resistance of 1 Ω.

The limiting capacity of a circuit breaker is its aptitude to limit short-circuit currents.

Installation guide Cascading 0

What is cascading?Cascading is the use of the current limiting capacity of circuit breakers at a given point to permit installation of lower-rated and therefore lower-cost circuit breakers downstream.The upstream compact circuit breakers acts as a barrier against short-circuit currents. In this way, downstream circuit breakers with lower breaking capacities than the prospective short-circuit (at their point of installation) operate under their normal breaking conditions.Since the current is limited throughout the circuit controlled by the limiting circuit breaker, cascading applies to all switchgear downstream. It is not restricted to two consecutive devices.

General use of cascadingWith cascading, the devices can be installed in different switchboards. Thus, in general, cascading refers to any combination of circuit breakers where a circuit breaker with a breaking capacity less than the prospective Isc at its point of installation can be used. Of course, the breaking capacity of the upstream circuit breaker must be greater than or equal to the prospective short-circuit current at its point of installation.The combination of two circuit breakers in cascading configuration is covered by the following standards:b IEC 60947-2 (construction)b NF C 15-100, § 434.3.1 (installation).

Coordination between circuit breakersThe use of a protective device possessing a breaking capacity less than the prospective short-circuit current at its installation point is permitted as long as another device is installed upstream with at least the necessary breaking capacity.In this case, the characteristics of the two devices must be coordinated in such a way that the energy let through by the upstream device is not more than that which can be withstood by the downstream device and the cables protected by these devices without damage.Cascading can only be checked by laboratory tests and the possible combinations can be specified only by the circuit breaker manufacturer.

220/240 V network downstream from a 380/415 V networkFor 1P + N or 2P circuit breakers connected between the phase and neutral on a 380/415 V network, with a TT or TNS neutral system, consult the 220/240 V cascading table to determine cascading possibilities between upstream and downstream circuit breakers.

Economy by means of cascadingThanks to cascading, circuit breakers with breaking capacities less than the prospective short-circuit current may be installed downstream from a current limiting circuit breaker.It follows that substantial savings can be made on downstream switchgear and enclosures.

Cascading tablesMerlin Gerin cascading tables are:b drawn up on the basis of calculations (comparison between the energy limited by the upstream device and the maximum permissible thermal stress for the downstream device)b verified experimentally in accordance with IEC standard 60947-2.For distribution systems with 220/240 V, 380/415 V and 440 V between phases, the tables of the following pages indicate cascading possibilities between upstream Compact/EasyPact and downstream Multi 9 and EasyPact circuit breakers.

Installation guide Motor protection 0

A circuit supplying a motor may include one, two, three or four switchgear or controlgear devices fulfilling one or more functions.When a number of devices are used, they must be coordinated to ensure optimum operation of the motor.Protection of a motor circuit involves a number of parameters that depend on:b the application (type of machine driven, operating safety, starting frequency, etc.)b the level of service continuity imposed by the load or the applicationb the applicable standards to ensure protection of life and property.The necessary electrical functions are of very different natures:b short circuit protectionb overload protection dedicated for motorb control (generally with high endurance levels)b isolation.

Protection functionsDisconnection functions:Isolate a motor circuit prior to maintenance operations.

Short-circuit protection:Protect the starter and the cables against major overcurrents (> 10 In).

Control:Start and stop the motor and, if applicable:b gradual accelerationb speed control.

Overload protection:Protect the starter and the cables against minor overcurrents (< 10 In).

Additional specific protection:b limitative fault protection (while the motor is running)b preventive fault protection (monitoring of motor insulation with motor off).

Overloads (I < 10 In)An overload may be caused by:b an electrical problem, for instance on the mains (loss of a phase, voltage outside tolerances, etc.)b a mechanical problem, for instance excessive torque due to abnormally high demands by the process or motor damage (bearing vibrations, etc.).A further consequence of these two origins is excessively long starting.

Impedance short-circuit (10 < I < 50 In)Deterioration of motor-winding insulation is the primary cause.

Short-circuit (I > 50 In)This type of fault is relatively rare. A possible cause may be a connection error during maintenance.

Overload protectionThermal relays provide protection against this type of fault. They may be:b integrated in the short-circuit protective deviceb separate.

Short-circuit protectionThis type of protection is provided by a circuit breaker.

Protection against insulation faultsThis type of protection may be provided by:b a residual current device (RCD)b an insulation monitoring device (IMD).
