## Long description

The LS MMS-100A motor protection circuit breaker is a high-performance electrical component engineered to provide reliable control and protection for electric motors operating within a current range of 70 to 90 amperes. This device serves as a critical safeguard in industrial and commercial electrical systems, effectively managing motor startup and operation while preventing damage from electrical faults.
The primary advantage of this circuit breaker lies in its robust design and precise calibration, which ensures consistent performance under demanding conditions. By integrating overload and short-circuit protection into a single compact unit, it simplifies panel design and reduces the need for additional protective components. Its durable construction supports long-term operational reliability, minimizing downtime and maintenance requirements in complex motor control circuits.
Suitable for
Industrial motor control centers
Commercial HVAC systems
Pumping stations and water treatment facilities
Conveyor belt systems and manufacturing machinery
This device may not be suitable for applications requiring current ratings outside the specified 70-90A range. It is also not intended for use in environments with extreme moisture, corrosive gases, or explosive atmospheres unless housed in an appropriately rated protective enclosure.
Key specifications
Current adjustment range: 70-90A
Function: Overload and short-circuit protection
Application: Motor control and protection
Design: Compact modular construction
To use the LS MMS-100A, mount the device onto a standard DIN rail or directly onto the control panel backplate within a suitable electrical enclosure. Connect the incoming power supply to the line-side terminals and the motor leads to the load-side terminals, ensuring all connections are tightened to the manufacturer's specified torque settings. Once installed, adjust the current dial to the specific full-load amperage of the connected motor to ensure accurate protection.
What to consider before purchase
Verify that the motor's full-load current falls within the 70-90A range
Ensure the control panel has sufficient space for the device dimensions
Confirm compatibility with existing electrical distribution infrastructure
Check that the ambient operating temperature is within the manufacturer's recommended limits
For optimal safety and performance, always perform a continuity and insulation test before energizing the circuit. Regularly inspect the terminals for tightness and ensure the device is free from dust or debris accumulation to maintain proper thermal dissipation.
