Circuit Breakers for Transformer Protection

ABB's MS132-T series includes fuseless circuit breakers that protect the primary side of transformers against overload and short circuits. These devices provide effective protection against winding failures by offering manual connection and disconnection. Suitable for the high starting current peaks of transformers, MS132-T offers security beyond standard protection methods.
 With a width of 45 mm and a capacity of 25 Amps, the MS132-T features a clear and reliable fault indication in the event of a short circuit. Features include a built-in disconnect function, temperature compensation and a lockable rotating handle, increasing ease of use and safety.
 The MS132-T series is equipped with various accessories: auxiliary and signal contacts, low voltage chokes, shunt tripping and power supply blocks. These accessories are compatible with the MS116, MS132 and MS165 series and offer special options for fast and practical single-phase installations.
