Enhance control-circuit signalling with the Lovato CNH11 auxiliary contact accessory. This slim 0.5 DIN module provides a dependable 1NO+1NC contact arrangement, rated Ith 6 A with Ui 500 V and 4 kV impulse withstand. Designed to fit Lovato CN25…, CN3210…, CN3201…, CN40… and CN63… contactors, the CNH11 integrates neatly into panels to deliver clear auxiliary switching for indication, interlocking and feedback tasks in industrial automation and motor control assemblies.
Built for longevity and compliance, this CN-series accessory offers a mechanical life of 3,000,000 cycles and meets IEC/EN 60947-1, 60947-4-1, 60947-5-1 and 61095. Operating from -5 to 55 °C with pollution degree 3, it suits installations up to 2000 m altitude. A maximum terminal tightening torque of 0.8 Nm and a light 44 g build simplify installation and maintenance in space-constrained control gear.
