Why Choose the ABB MS165-54 Manual Motor Starter?
The ABB MS165-54, order code 1SAM451000R1016, is a compact and powerful manual motor starter designed for manual switching and protection of electric motors. As part of the ABB MS165 motor protection range, it provides fuse-free protection against short circuits, overloads and phase failures in both three-phase and single-phase applications.
With an adjustable thermal overload setting range of 40–54 A and a rated operational current of 54 A, the MS165-54 allows motor protection to be matched accurately to the connected equipment. The device provides trip class 10 protection and incorporates a built-in disconnect function, temperature compensation, a trip-free mechanism and a rotary operating handle with clear switch position indication.
The MS165-54 provides a rated operational power of 22 kW at 400 V AC, a 30 kA service short-circuit breaking capacity at 400 V AC and an 810 A instantaneous short-circuit release. Its compact 55 mm-wide format makes it suitable for demanding industrial motor control panels, machinery and automation systems.

Reliable Motor Protection for Industrial Machinery
Manual motor starters such as the ABB MS165-54 combine manual motor switching with protection against short circuits, overloads and phase failures. The adjustable thermal overload release can be set between 40 A and 54 A to match the connected motor, while the 810 A instantaneous magnetic release provides rapid protection when a short-circuit condition occurs.
The MS165 series is designed for demanding motor protection applications and includes a built-in disconnect function, temperature compensation and a trip-free mechanism. The rotary handle provides clear switch position indication and can be locked to protect against unauthorised changes, while a separate indication window clearly identifies a short-circuit trip.
