Suitable for

• Industrial automation systems
• Motor control centers
• Heating and ventilation equipment
• Conveyor belt systems
• Pump control applications

When it may not be suitable

This device is not intended for use in circuits where the motor current falls outside the specified 2.8 to 4A range. It is also not suitable for applications requiring electronic overload protection with advanced communication features or specialized diagnostic capabilities.

Key specifications

• Current adjustment range: 2.8 - 4A
• Size: S00
• Protection type: Thermal overload
• Mounting type: Direct mounting

How to use

The relay is designed for direct mounting onto compatible contactors. Once installed, the current range should be set using the adjustment dial on the front of the device to match the nominal current of the motor being protected. Ensure that all electrical connections are tightened according to the manufacturer's torque specifications to prevent loose contacts and potential heating issues.

What to consider before purchase

• Verify the nominal current of your motor is within the 2.8 - 4A range.
• Ensure compatibility with your existing contactor size S00.
• Check the environmental conditions of the installation site to ensure they meet the device's operating specifications.

Usage recommendations

Regularly inspect the relay for any signs of physical damage or loose connections. Test the trip function periodically to ensure the protection mechanism is fully operational and capable of disconnecting the circuit during an overload event.
