MT-TS- 250A- 3P

MT-TS-250A-3P, Motorised MCB, 3 poles

Code: P20H64.

  • Poles: 3
  • In (A): 250 A

INFORMATION

Description

MT-TS 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.

The switch can be reconnected in two ways, depending on how the operation mode is set in the motor group:

  • “MANU”: done manually on the switch itself by turning it to OFF and then ON.
  • “AUTO”: done by means of an electrical impulse that follows the OFF-ON sequence.

Applications

The MT-TS series are motorized automatic switches that can be operated remotely and are valid for any application that requires remote connection/disconnection. They are an essential component for providing overload protection with reclosing.
