Motor protection circuit breakers MMS-32S – reliable protection for electric motors

Motor protection circuit breakers of the MMS-32S series, manufactured by LS Electric (formerly LSiS), are a key element in protecting electric motors in industrial and commercial installations. They provide effective protection against short circuits, overloads and phase imbalance, which translates into a longer lifespan of motors and minimization of downtime. The MMS-32S 22A model is designed to work with motors up to 10 kW, offering optimal parameters for a wide range of applications.

Functionality and application

These circuit breakers are used in automation control circuits and electrical systems powering various types of machines and devices. Their construction based on solid materials and precise workmanship guarantees reliable operation even in difficult environmental conditions. Thanks to the possibility of adjusting the current setting, the circuit breaker can be adapted to the specific needs of the protected motor. Remember that the selection of the appropriate current setting (Inas) should be made according to the formula: Inas = In * 1.1, where In is the rated motor current.

Key features and benefits

• Versatility: Suitable for working with motors with different parameters – AC-3 operating rated current for Ue=400V is 14-22A.
• High reliability: Compliance with IEC60947-2(-4) ensures compliance with stringent safety and quality standards.
• Protection against multiple threats: Protects against short circuits, overloads and phase imbalance, protecting both the motor and the entire electrical installation.
• Durability: Designed for intensive operation – mechanical endurance is 100,000 operations, and electrical endurance is also 100,000 operations at a frequency of 25 operations per hour.
• Compact dimensions: Dimensions 45 x 105 x 75 mm make it easy to install even in tight switchgear spaces.
• Safety: The IP20 enclosure protection degree provides protection against accidental contact.
• DC operation possible: The circuit breaker can also be used in direct current circuits.

The MMS-32S circuit breaker is a solid solution for both professional installers and end-users looking for reliable protection for their electric motors. Its versatility and ease of installation make it an ideal choice for a wide range of industrial and commercial applications.
