Suitable for
Industrial motor control systems
Automation and manufacturing machinery
HVAC systems and pump control
Conveyor belt motor protection
This device may not be suitable for applications requiring current ratings outside the 2.5 to 4A range. It is intended for industrial use and should not be installed in environments with extreme moisture, corrosive gases, or excessive vibration without appropriate protective enclosures.
Key specifications
Current adjustment range: 2.5 - 4A
Protection functions: Short-circuit, overload, and phase failure
Mounting type: DIN rail or screw mounting
Application: Motor protection and control
To use the LS MMS-32H, ensure the device is correctly mounted on a standard DIN rail or panel. Connect the power supply and motor cables to the designated terminals, ensuring all connections are tightened to the manufacturer's specified torque. Once installed, set the current dial to the nominal current rating of the motor being protected. The device can be manually switched on or off using the front-mounted toggle, and it will automatically trip in the event of an electrical fault.
What to consider before purchase
Verify that the motor's nominal current falls within the 2.5 - 4A range
Ensure compatibility with your existing control panel layout
Check local electrical regulations for installation requirements
For optimal performance, regularly inspect the terminal connections for tightness and ensure the device is kept free of dust and debris. Always disconnect the power supply before performing any maintenance or adjustments to the circuit breaker.
