Motor protection circuit breakers – reliable drive protection

Motor protection circuit breakers are a key element in protecting electric motors from overloads, short circuits and phase failure. These devices not only protect the motor, but also ensure the safe operation of the entire installation. The MS132-32 model, with a rated current of 32A, combines compact dimensions (45 mm wide) with high efficiency. It is an ideal solution for both professional installers and end users looking for reliable motor protection.

This three-pole (3P) circuit breaker is designed to operate in circuits with a rated voltage of 250-690V. It provides effective protection with a rated power of up to 15 kW for 400V AC and 230V AC. High short-circuit breaking capacity (50 kA at 400V AC) guarantees a quick response in the event of a failure, minimizing the risk of damage to the motor and installation. The built-in thermal release protects the motor winding against overload, and the phase failure sensitivity increases the safety of operation in three-phase networks.

The MS132-32 circuit breaker is characterized by an adjustable overload release setting range (25-32 A) and short-circuit release (480-480 A), allowing for precise adjustment to the characteristics of the protected circuit. The connection of the main contacts is made using screw connections, which ensures a secure and durable connection of the wires. Operation is performed using a knob, allowing manual switching on and off of the motor. The device has a protection class of IP20, which means protection against finger contact. Power loss is 9.3 W.

The application of this type of circuit breakers is wide – from protecting motors in industry and workshops, to home and commercial installations. The compact dimensions allow for mounting in tight switchboards, and the high quality of workmanship guarantees long-lasting and trouble-free operation. Additionally, the possibility of use in single-phase and three-phase applications increases the versatility of the device. This circuit breaker is part of a complete device in a housing, ready for mounting after unpacking.
