MS165-42 Motor starter switch 1SAM451000R1015

Motor starter for reliable motor protection

This three-pole motor starter MS165-42 from ABB is a robust solution for controlling and protecting electric motors. It provides effective protection against overloads, short circuits and phase failure, which translates to a longer life of connected devices. This starter is designed to operate in three-phase installations with a rated voltage of 250 to 690V and allows for manual switching on and off of motors.

Functionality and application

The MS165-42 starter finds wide application in industry, construction and workshops. Its compact design (width 55mm) facilitates installation, especially where space is limited. The adjustable overload release range (30-42A) allows adaptation to specific application needs. Equipped with a knob, it enables intuitive operation and clear indication of the switch status. The short-circuit capacity Icu of 50kA at 400V guarantees the safety of the installation in the event of a failure.
