Suitable for

• Industrial motor control centers
• Commercial HVAC systems
• Conveyor belt motor protection
• Pump and fan control applications
• Manufacturing machinery automation

This circuit breaker may not be suitable for applications requiring current ratings outside the 0.63 to 1A range. It is also not intended for use in high-voltage distribution networks or environments that exceed the specified environmental operating conditions for this series.

Key specifications

• Adjustable thermal release range: 0.63 - 1A
• Function: Overload and short-circuit protection
• Compact modular design
• Suitable for motor control applications

How to use

The LS MMS-32S should be installed by a qualified electrician in accordance with local electrical codes. It is typically mounted on a standard DIN rail within an electrical enclosure. Once mounted, the motor leads are connected to the output terminals, and the power supply is connected to the input terminals. The thermal release current should be adjusted using the dial on the front of the device to match the full-load current rating of the motor being protected. After installation, perform a functional test to ensure the device trips correctly under simulated fault conditions.

What to consider before purchase

• Verify that the motor full-load current falls within the 0.63 - 1A range
• Ensure the enclosure provides adequate protection against dust and moisture
• Check compatibility with existing DIN rail mounting systems
• Confirm the short-circuit breaking capacity meets your system requirements

Usage recommendations

Always ensure that the thermal release dial is set precisely to the motor's rated current to prevent nuisance tripping or inadequate protection. Regularly inspect the terminals for tightness and check for any signs of overheating during routine maintenance.
