Load-break circuit breaker 90 AM Range

The 90 AM range, in addition to auxiliaries common for the all circuit breakers, comprises many modular accessories for the protection, command, programming, measurement and signalling in electrical systems. Benefits Intelligent load management P-COMFORT prevents the interruption of electrical power: in the event of an overload, it only disconnects non-preferred loads, and then automatically reactivates them after a predefined time, thus eliminating any inconvenience due to blackout. Overvoltage under control The LST surge protection device range offers maximum protection against intense atmospheric discharges caused by direct and indirect lightning. The easy-to-extract cartridges makes it quicker and more convenient to replace used cartridges. Simplified accessory management Auxiliary contacts and trip coils, common to all circuit breakers, guarantee simplicity, interchangeability, multiple uses and rationalisation of the items.
