Suitable for

• Industrial motor control centers
• Commercial HVAC systems
• Conveyor belt drive protection
• Pump and fan motor management
• Automation and control panel integration

When it may not be suitable

This device is not intended for motors exceeding the 0.75 kW power rating or for applications requiring a thermal release range outside of the 1.6 - 2.5 A specification. It should not be used in environments where the ambient conditions exceed the manufacturer's specified temperature or humidity limits.

Key specifications

• Rated operational power: 0.75 kW
• Thermal release adjustment range: 1.6 - 2.5 A
• Connection type: Screw and Push-In terminals
• Protection function: Overload and short-circuit protection
• Application: Motor protection

How to use

Installation should be performed by a qualified electrician in accordance with local electrical standards. Begin by mounting the circuit breaker onto a standard DIN rail within the control cabinet. Connect the power supply and the motor leads using either the screw terminals or the Push-In connectors, ensuring that all wires are stripped to the correct length and securely fastened. Once installed, adjust the thermal release dial to the rated current of the specific motor being protected. After the initial setup, perform a functional test to ensure the device trips correctly under simulated conditions if required by the system design.

What to consider before purchase

• Verify the full-load current of your motor matches the 1.6 - 2.5 A range
• Ensure the motor power does not exceed 0.75 kW
• Confirm the available space in your control panel for DIN rail mounting
• Check if your wiring setup is compatible with Push-In or screw terminal connections

Usage recommendations: Regularly inspect the terminal connections for tightness and check the device for any signs of physical damage or discoloration to ensure continued reliable operation.
