Motor protection circuit breakers MMS-63S – reliable motor protection

The MMS-63S series motor protection circuit breakers are devices designed to effectively protect electric motors against overloads and short circuits. They are a key element in ensuring the safe and reliable operation of automation systems and electrical installations. The MMS-63S 40A model, thanks to its adjustable setting range, allows adaptation to the specific needs of the application.

Characteristics and application

The MMS-63S 40A circuit breaker is characterized by a thermal-magnetic tripping method, which means it reacts to both temperature increases caused by overloads and sudden current surges associated with short circuits. This ensures comprehensive protection of the connected motors. The rated operating current is 40A, and the overload release setting range is 28-40A – this provides flexibility in selecting the appropriate protection for different loads. The device is designed to operate in circuits with a rated voltage of 230…690V.

• Application: ideal for protecting electric motors in industry, construction and commercial installations.
• Mounting: easy mounting on a DIN rail thanks to screw fastening.
• Degree of protection: IP20 provides basic protection against contact and ingress of solid objects.
• Lever type: rotary – facilitates operation and quick identification of the circuit breaker status.

Advantages for installers and end users

The MMS-63S 40A circuit breaker is a solution that will be appreciated by both professionals involved in electrical installations and end users who care about the safety of their devices:

• Versatility: Adjustable current range allows use in various applications without the need to have many types of circuit breakers.
• Simple installation: Quick and easy mounting on a DIN rail saves time during installation and maintenance.
• Reliability: Thermal-magnetic tripping method guarantees effective protection against overloads and short circuits, minimizing the risk of failures and downtime.
• Safety: Ensures safe operation of electric motors, protecting them from damage and extending their service life.
• Compact dimensions: Allow installation in a limited space of the switchgear cabinet.
