MS132-4.0 Motor starter switch 1SAM350000R1008

Robust motor protection in a compact housing

The MS132-4.0 motor starter is a reliable device designed to protect electric motors from overload, short circuit and phase failure. Designed for a wide range of applications – from workshops, through production plants, to commercial installations – it ensures safe and efficient operation of drives. Compact dimensions (45 mm width) facilitate mounting even in tight spaces.

Functionality and safety in one device

This three-pole starter (3P) is characterized by a rated continuous current of 4A and is adapted to work in networks with a voltage of 250-690V. The short-circuit breaking capacity at 100kA at 400V guarantees effective protection of the installation in the event of a failure. The built-in thermal release protects the motor from overheating, and the phase failure sensitivity prevents damage caused by voltage asymmetry. The adjustment range of the overload release (2.5-4A) allows for precise adaptation to the load characteristics, and the short-circuit range (50-50A) ensures a quick response in emergency situations.

Installation and application

The MS132-4.0 starter with screw connection is easy to install and maintain. Designed for manual switching of motors on and off, it performs well in applications requiring reliable protection and ease of use. The rated operating power for AC-3 is 1.5kW at 400V and 230V, making it a suitable choice for various drives. The device's construction as a complete unit in a housing ensures readiness for immediate use after mounting on a rail or directly on the device. Additionally, the knob as an actuator allows for convenient control of the starter.
