How to use

The relay is typically mounted directly onto a compatible contactor. Once installed, the current setting should be adjusted using the dial on the front of the unit to match the full-load current rating of the motor it is protecting. Ensure all electrical connections are tightened to the manufacturer's torque specifications to prevent overheating at the terminals. Regular inspections should be performed to verify that the relay is functioning correctly and that the trip settings remain appropriate for the application.

What to consider before purchase

Verify that the motor's full-load current falls within the 23-32A range.
Ensure compatibility with the existing contactor model.
Check that the installation environment meets the required safety standards for industrial electrical components.
