MS132-T circuit breakers for transformer protection

0.10 to 25 A – with thermal and electromagnetic protection

Description
Circuit breakers for transformer protection are electro mechanical protection devices specially designed to
protect control transformers on the primary side. They allow fuse-less protection against overload and short-
circuit, saving space and cost and ensuring a quick reaction under short-circuit condition by switching off
the transformer within milliseconds. The short-circuit current setting is fixed to 20 times the operating current 2
to handle the high inrush current generated by transformers. The device allows manual connection and
2CDC241001F0014 disconnection of the transformer from the mains.
MS132-T is a 45 mm (width) compact and powerful range for transformer protection up to 12.5 kW (400 V)
/ 25 A. This type has also a clear and reliable indication of fault in a separate window in the event of short-
circuit tripping. Further features are the build-in disconnect function, temperature compensation, trip-free
MS132-10T mechanism and a rotary handle with a clear switch position indication. The handle is lockable to protect against
unauthorized changes. Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, power in-feed
blocks are available as accessory. These are suitable throughout the MS116/MS132/MS165-range. Moreover
ABB offers special accessories for fast single phase setup.
