MT-TSD-250A-3P, Motorised circuit-breaker suitable for residual current protection, 3 poles
MT-TSD series automatic switch with remote control for currents from 80 to 630A, with both 3 and 4 poles.
Provides short-circuit and overload protection, and is also used as a circuit breaker, as it features a trigger coil for use with a differential relay.
The switch can be reconnected in two ways, depending on how the operation mode is set in the motor group:
The MT-TSD series are motorized automatic switches that can be operated remotely and are valid for any application that requires remote connection/disconnection.
They are also used as a circuit breaker associated with automatic reclosing relays, such as the RGU-10 MT. They are an essential complement to provide overcurrent and earth leakage protection with automatic reclosing.
