Reliable Choice for Motor Protection

Installed on a pump motor, set the dial to 3.5A, and let it run. I checked temperatures after long cycles and everything stayed within safe ranges. Exactly what I needed for protecting small motors.

Perfect Size for Tight Panels

I love how compact this relay is. I put it into a small automation cabinet and still had room for wiring channels. The DIN rail clip is secure and does not wiggle. Great for OEM and retrofit applications.

Accurate Overload Protection

I used this for a fan motor in a commercial unit. The adjustable range gives the flexibility I need. It tripped correctly during a simulated overload test. Exactly what I expect from IEC equipment.

Quality You Can Feel

This is not cheap plastic. The relay feels solid and the terminals hold wire well. It complies with IEC/EN standards which always gives me peace of mind when using it inside industrial machinery.
