Motorized circuit breaker for currents over 63 A

Description

Automatic switch with remote control of the MT-FDE Series, for currents of 80 to 250 A, 3 and 4 poles. Responsible for the protection against shortcircuits and overloads, but also used as a circuit breaker. The switch can be reclosed with two methods, depending on the adjustment of the motor group in the operations mode:

• “MANU”: executed manually with the same switch, following the OFF and ON sequence.
• “AUTO”: carried out with an electrical impulse, following the OFF and ON sequence.

Applications

The MT-FDE Series is composed of motorized circuit breakers that can be activated remotely and can be used in any application that uses a connection/disconnection remote control. They are also used as circuit breakers associated to the self-reclosing relays, for example, RGU-10 MT or RRM. They are a vital accessory in the self-reclosing overload and residual current protection process.
