Self-reclosing overload and earth leakage protection Overcurrent and earth leakage protection and self-reclosing Motorized circuit-breaker (from 63 A) 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. Nominal cut-out power (IEC 947-2) MT-FDE: 25 kA, in accordance with IEC 60947-2 MT-FEE: 36 kA Typical curve Nominal working voltage The switch can be reclosed with two methods, depending on the adjustment of the motor group in the operations mode: Work frequency range Operating temperature Storage temperature }} “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. Nominal voltage Minimum voltage Activation impulse Deactivation impulse Construction features Fixing Application 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. Panel (base + plug-in socket) They are also used as circuit breakers associated to the self-reclosing relays, for example, RGU-10 MT orRRM. They are a vital accessory in the self-reclosing overload and earth leakage protection process.
