Why Choose the MS165-20 [1SAM451000R1012]
The MS165 is a compact motor protection device designed for motors up to 45 kW (400 V) and 80 A, housed within a 55 mm width. It provides reliable protection against overload and phase failure, featuring a trip class 10 rating for precise response. A dedicated fault indication window clearly signals short-circuit trips, enhancing diagnostic clarity. Key features include an integrated disconnect function, temperature compensation, a trip-free mechanism, and a rotary handle with clear switch position indication. Suitable for both single and three-phase applications, the manual motor starter—also referred to as a motor protection circuit breaker—offers a lockable handle to prevent unauthorized operation. A range of accessories is available, including auxiliary and signalling contacts, undervoltage releases, shunt trips, and power in-feed blocks, all compatible across the MS116, MS132, and MS165 series.
