ABB MS132-6.3T Manual Motor Protector: Compact 4.0-6.3A Circuit Breaker with Fuse-less Overload and Short-Circuit Protection for Control Transformers
The ABB MS132-6.3T Manual Motor Protector is a compact and efficient solution for safeguarding control transformers on the primary side. With a width of just 45 mm, this device is designed to provide fuse-less protection against overload and short-circuit conditions. It features a rated operational current of Ie = 6.3 A and a fixed short-circuit current setting at 20 times the rated operational current, effectively managing the high inrush current typical of transformers.
This circuit breaker offers a rated service short-circuit breaking capacity of Ics = 100 kA at 400 VAC and operates with a trip class 10. It includes a built-in disconnection function, allowing for manual connection and disconnection of the transformer from the mains. 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, auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, power in-feed blocks, and terminal spacers are available as accessories. The ABB MS132-6.3T is an ideal choice for reliable and secure transformer protection.
