Descriere

Small-sized AC contactors of KMI series for load current from 9 to 95 A are designed for starting, stopping and reversing of asynchronous electric motors with a short-circuited rotor under voltage up to 660V (category of application - AC-3), as well as for remote control of lighting circuits, heating circuits and various low-inductive loads (category of application AC-1). The area of application of KMI series small-sized contactors: control of fans, pumps, thermal curtains, furnaces, overhead cranes, machines, lighting, systems of automatic load transfer (ALT). As per design and technical characteristics, the KMI series small-sized contactors comply with international and Russian standards GOST R 50030.4.1-2002 (IEC 60947-4-1-2000).High switching endurance.
