## Long description

The LS MMS-63S motor protection circuit breaker is a high-performance device engineered to provide comprehensive protection for electric motors operating within the 28 to 40A current range. This compact and robust unit is designed to safeguard electrical systems by monitoring current flow and interrupting power in the event of faults, thereby preventing damage to motors and associated equipment in industrial and commercial environments.
Advantages
This motor protection circuit breaker offers exceptional reliability through its integrated thermal and magnetic trip mechanisms. It effectively detects overloads, short circuits, and phase failures, ensuring that the motor is disconnected before thermal damage occurs. The device is built for durability and ease of integration into standard electrical panels, providing a stable and long-lasting solution for motor control and protection needs.
Suitable for
Industrial motor control centers
Commercial HVAC systems
Pump and compressor motor protection
Conveyor belt drive systems
Manufacturing machinery and automation equipment
This device may not be suitable for applications requiring current ratings outside the 28-40A range or for environments with extreme environmental conditions that exceed the manufacturer's specified operating temperature or ingress protection ratings. It is also not intended for use in high-voltage distribution networks beyond its rated capacity.
Key specifications
Current adjustment range: 28 to 40A
Protection functions: Short circuit, overload, and phase failure
Mounting type: DIN rail or panel mount
Operational reliability: High-speed tripping mechanism
The device should be installed by a qualified professional in accordance with local electrical codes. It is mounted onto a standard DIN rail within an electrical enclosure. Once installed, the current setting dial must be adjusted to the specific full-load current rating of the motor being protected to ensure accurate thermal overload protection. The unit features a manual toggle switch for local operation and status indication.
What to consider before purchase
Verify that the motor's full-load current falls within the 28-40A range
Ensure the enclosure provides adequate space and ventilation
Check compatibility with existing electrical distribution hardware
Confirm the required short-circuit breaking capacity for your specific installation
For optimal performance and safety, regularly inspect the terminal connections for tightness and ensure the device is free from dust and moisture accumulation. Always verify the settings after any maintenance or motor replacement.
