Electrical consistency

Each product complies with or enhances system performance at co-ordination level: breaking capacity, Isc, temperature rise, etc. for more safety, continuity of supply (discrimination) or economic optimisation (cascading).
The leading edge technologies employed in Merlin Gerin’s Guiding System ensure high performance levels in discrimination and cascading of protection devices, electrodynamic withstand of switches and current distributors, heat loss of devices, distribution blocks and enclosures.

Example

Continuity of supply

Discrimination guarantees co-ordination between the operating characteristics of serial-connected circuit breakers. Should a fault occurs downsteam, only the circuit-breaker placed immediately upstream from the fault will trip.

The temperature rise tests performed in the laboratory guarantee safety and durability of installations.

Mechanical consistency

Each product adopts dimensional standards simplifying and optimising its use within the system. It shares the same accessories and auxiliaries and complies with global ergonomic choices (utilisation mode, operating mode, setting and configuration devices, tools, etc.), making its installation and operation within the system a simpler process.

Example

Type tested switchboards by simple assembly

Direct connection of the Canalis KT busbar trunking on the Masterpact 3200A circuit breaker.

Prefabricated and tested solutions upstream and downstream from the device complying with the IEC 60 439-1 switchboard standard.

Communication consistency

Each product complies with global choices in terms of communication protocols (Modbus, Ethernet, etc.) for simplified integration in the management, supervision and monitoring systems.

Example

Transparent ready : knowledge at all times of installation status
Thanks to the use of standard Web technologies, you can offer your customers intelligent Merlin Gerin switchboards allowing easy access to information : follow-up of currents, voltages, powers consumption history, etc.
