MS132-0.4 - Motor starter 1SAM350000R1003

Motor starter switches MS132 – reliable motor protection

Motor starter switches MS132 are compact protective devices for electric motors, designed to operate in three-phase and single-phase installations. They provide effective protection against overload and short circuit, and also allow manual disconnection of the circuit. Their versatility makes them ideal for both professional installers and end-users looking for reliable protection of their equipment.

Construction and functionality

The MS132 construction is based on the thermomagnetic principle, which means it combines thermal protection (against overload) and magnetic protection (against short circuit). A built-in overload release class 10 protects the motor from long-term load, while a fast-acting short-circuit release reacts immediately to sudden current surges. Additionally, these switches have a protection tripping indicator (TRIP) which facilitates identification of the cause of the disconnection. The handle locking option provides additional safety during maintenance or repair.

Application and parameters

MS132 motor starters are used in a wide range of industrial and commercial applications, from simple devices to more advanced automation systems. They are designed to protect motors with a power of up to 0.09 kW at 400 V and 0.09 kW at 230 V. The rated continuous current (Iu) is 0.4 A, and the overload release setting range is 0.25…0.4 A. The short-circuit breaking capacity Icu at 400 V AC is as high as 100 kA, which guarantees effective protection even in the event of high short-circuit currents. Made of high-quality materials, they ensure durability and reliable operation in various environmental conditions (IP20).

• Versatility: Can be used in single-phase and three-phase systems.
• Protection: Effective protection against overload and short circuit thanks to the thermomagnetic release.
• TRIP indicator: Facilitates diagnosis of the causes of device disconnection.
• Handle lock: Increases safety during maintenance and repair.
• Compact dimensions: The housing width is only 45 mm, making it easy to install in tight spaces.
• Phase asymmetry detection: Additional function increasing the safety of the electrical installation.
• Wide range of operating voltages: From 250 V to 690 V AC ensures compatibility with various electrical installations.
• Thermal protection: Protects the motor from damage caused by overheating.

Thanks to these features, MS132 motor starters are an optimal solution for anyone who values reliability, safety and ease of use.
