MS132-25 Motor starter switch 1SAM350000R1014

Motor protection circuit breakers – reliable drive protection

The MS132-25 motor circuit breaker is a compact device designed to protect electric motors from overload and short circuit. Designed for both three-phase and single-phase installations, it is a key element ensuring safe and efficient drive operation. Its wide range of applications includes various machines and devices where reliable motor protection is required.

Characteristics and application

This model, catalog number 1SAM350000R1014, is characterized by a rated current of 25A and a short-circuit breaking capacity of up to 50kA at 400V AC. It provides effective protection in the range of 20 to 25A, making it an ideal solution for motors with a power of up to 11kW at 400V AC or 230V AC. Equipped with thermal protection, it reacts to an increase in winding temperature, protecting against their damage. Additionally, it has a built-in phase failure detection function, which increases safety in the event of power supply irregularities. The device is based on a thermal-magnetic principle – the thermal release protects against overload, and the electromagnetic release against short circuit.

Advantages and benefits

• Compact dimensions: Width of 45 mm allows for mounting in tight spaces in switchboards and control cabinets.
• High short-circuit breaking capacity: Ensures a quick and effective response in the event of a short circuit, minimizing the risk of damage to the motor and installation.
• Thermal protection: Protects the motor from overheating caused by overload or improper operation.
• Phase failure detection: Increases safety by disconnecting the circuit in the event of a missing phase.
• Adjustable current range: Allows precise adjustment to the characteristics of the protected motor (setting range: 20-25A).
• Easy installation: Mounting on a TH-35 rail facilitates installation and device replacement.
• Durable construction: Ensures long-lasting and reliable operation in various environmental conditions (protection class IP20).
• Wide range of operating voltages: Possibility of use in installations with a voltage of 250V to 690V AC.

The MS132-25 circuit breaker is a solid solution for professionals and end-users looking for reliable protection of electric motors. Its compact size, high performance and rich set of functions make it an optimal choice for various industrial and commercial applications.
