Why Choose the ABB MS165-42 Manual Motor Starter?
The ABB MS165-42, order code 1SAM451000R1015, is a compact and powerful manual motor starter designed for switching and protecting electric motors and electrical installations. Part of the ABB MS165 motor protection range, it provides reliable protection against motor overload, phase failure and short-circuit conditions in both three-phase and single-phase applications.
With an adjustable thermal overload setting range of 30–42 A and a rated operational current of 42 A, the MS165-42 allows motor protection to be matched accurately to the connected equipment. Its thermomagnetic release system combines thermal overload protection with an instantaneous 630 A short-circuit release, while trip class 10 characteristics provide dependable motor protection.
The MS165-42 provides a rated operational power of 22 kW at 400 V AC and a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC. Its compact 55 mm width, screw connection and robust three-pole construction make it suitable for demanding industrial motor control panels, machinery and automation systems.
