• Commercial HVAC equipment
• Conveyor belt motor protection
• Pump and fan control applications

When it may not be suitable

This device is not intended for use with motors exceeding the 0.75kW power rating or those requiring current settings outside the 1.6 - 2.5A range. It is also not suitable for applications requiring specialized protection features such as ground fault detection or advanced electronic communication protocols.

Key specifications

• Number of poles: 3
• Current adjustment range: 1.6 - 2.5A
• Maximum motor power: 0.75kW
• Protection type: Thermal and magnetic release

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The breaker is typically mounted on a standard DIN rail within an electrical enclosure. Once mounted, connect the power supply to the input terminals and the motor leads to the output terminals. Use the adjustment dial on the front of the unit to set the thermal release current to match the full-load current rating of your specific motor. After installation, verify the connections and perform a test run to ensure the motor starts and stops correctly.

What to consider before purchase

• Verify the full-load current rating of your motor matches the 1.6 - 2.5A range
• Ensure the power rating of your motor does not exceed 0.75kW
• Check the available space in your electrical cabinet for DIN rail mounting
• Confirm compatibility with your existing control circuit voltage

Usage recommendations

Always ensure the power supply is disconnected before performing any installation or maintenance work on the circuit breaker. Regularly inspect the terminals for tightness and check for signs of thermal stress to maintain optimal performance.
