The adjustable current range allows for precise calibration to match the specific requirements of the connected motor, ensuring optimal protection and preventing unnecessary downtime caused by nuisance tripping or motor damage.

Suitable for

• Industrial automation systems
• Motor control centers
• HVAC equipment and ventilation systems
• Conveyor belt drives
• Pumping stations

This device is not intended for use in high-voltage power distribution networks or as a primary disconnect switch for large-scale industrial machinery exceeding its specified power rating. It is also not suitable for environments where extreme moisture or corrosive gases are present without appropriate protective enclosure housing.

Key specifications

• Number of poles: 3
• Rated operational power: 0.55kW
• Adjustable thermal release range: 1-1.6A
• Protection type: Short-circuit and overload
• Mounting type: DIN rail or screw mounting

The device is designed for straightforward installation within a control cabinet. It should be mounted on a standard DIN rail or secured via screws according to the manufacturer's guidelines. Once installed, the thermal release should be adjusted to the rated current of the motor being protected. The manual toggle switch allows for easy local control, enabling operators to start or stop the motor and reset the breaker after a trip event.

What to consider before purchase

• Verify the full load current of your motor matches the 1-1.6A adjustment range.
• Ensure the installation environment meets the required IP rating for the enclosure.
• Check compatibility with existing DIN rail configurations in your control panel.

Usage recommendations: Always ensure that the circuit breaker is installed by a qualified electrician in accordance with local electrical codes. Regularly inspect the terminals for tightness and check for any signs of thermal discoloration to ensure long-term performance and safety.
