MS132-2.5A Motor starter switch 1SAM350000R1007

Motor starter – reliable drive protection

This three-pole motor starter MS132-2.5A from ABB is a compact and economical device designed to protect electric motors. It provides effective protection against overload and short circuit, and also offers a circuit disconnection function. The device is ideal for both professional installers and end-users looking for a reliable solution to protect their motors. A width of only 45 mm allows for easy installation in limited spaces.

Functionality and application

The MS132-2.5A starter is used for manual switching on and off of motors, and also protects them against the effects of overload, short circuit and phase failure. A rated continuous current of 2.5 A and a breaking capacity of 100 kA at 400 V AC guarantee safe and efficient operation of the installation. The device works perfectly in three-phase installations, but can also be used in single-phase systems. The adjustable overload release range (1.6 - 2.5 A) allows for precise adjustment to the load characteristics.

Design features and benefits

The starter is characterized by a solid construction in a housing providing an IP20 degree of protection. A knob with a clear indication of the switch position makes operation easier, and a screw connection of the main contacts ensures secure and durable connections of wires with a cross-section from 1x1mm² to 6mm². The built-in temperature compensation function ensures stable operation over a wide range of ambient temperatures (-25°C to +70°C). Additionally, the starter has thermal protection, which protects against overheating of the motor. It is worth mentioning the sensitivity to phase failure, which further increases the safety of the installation. Power losses of 5.4 W minimize energy consumption during device operation.
