The bimetallic device protects attached equipment from overload current and phase loss, preventing damage caused by overheating. It clips onto a contactor from the 100-K series to make a stable and shock-resistant connection. Two auxiliary contacts allow for extra connections to the coil, which makes your wiring easier. You can use this overload relay in applications such as motor starters and motor control centres._x000D_ • Operating temperature range of -20°C to +60°C makes it suitable for use in harsh environments_x000D_ • Screw terminals help you make secure electrical connections that won't be dislodged by vibration_x000D_ • Choice of automatic or manual reset for flexible use_x000D_ Standards and Certifications_x000D_ • IEC/EN 60947-1,-4-1,-5-1_x000D_ • UL 508_x000D_ • CSA 22.2.

Current flows through this strip, and when it exceeds a set value the metals bend, breaking the circuit to shut off the supply to the contactor coil.
