The ABB MS132-10T is a compact manual motor protector designed specifically for transformer protection. With a width of just 45 mm, this device is engineered to safeguard control transformers on the primary side, offering a rated operational current of 10 A. It provides fuse-less protection against both overload and short-circuit conditions, with a short-circuit current setting fixed at 20 times the rated operational current to effectively manage the high inrush currents typical of transformers.
This circuit breaker features a built-in disconnection function, allowing for manual connection and disconnection of the transformer from the mains. It boasts a rated service short-circuit breaking capacity of 100 kA at 400 VAC and adheres to a trip class 10. Additional features include temperature compensation, a trip-free mechanism, and a rotary handle with clear switch position indication and short circuit trip indicator. The handle is lockable to prevent unauthorized adjustments.
For enhanced functionality, the MS132-10T can be equipped with auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, power in-feed blocks, and terminal spacers, making it a versatile choice for transformer protection needs.
