Compact but Built for Industrial Duty

What I appreciate most is how compact this relay is while still feeling industrial-grade. It fits neatly into tight control panels without crowding other components. The screw terminals hold securely, and the 1NO/1NC auxiliary contacts make it simple to integrate signaling into the control circuit.

Excellent Protection for Mid-Range Motors

I installed this overload relay on a small compressor motor running within the 4-6A range, and it performs exactly as it should. The adjustment dial is precise and easy to set. It integrates perfectly with LC1-D contactors, and the trip response during testing was accurate and consistent. Solid motor protection.
