The KT-6633 contactor is a three-pole electromagnetic AC contactor for a rated current of 250A ~ 380V with a pick-up coil for -110V -220V with two NO and two NC auxiliary contacts, with an air-cooled type. G-contactor with DC closing coil. C-contactor for continuous operation only. Contactor KT-6633 technical characteristics Rated current of the main contacts - 250A. Alternating voltage 24V, 48V, 55V, 110V, 220V, 380V Number of poles -3 Additional block contacts Degree of protection IP00 Mounting bolt Allowable frequency of switching 1200 cycles per hour Operating temperature range from -45 to +40 degrees Celsius KT-6633 electromagnetic contactors open version of general use are intended for switching on and off receivers of electrical energy. AC contactors are used to control three-phase asynchronous electric motors with a squirrel-cage rotor, to remove starting resistors, to turn on three-phase transformers, brake electromagnets and other electrical devices. Contactors KT-6633 are also used in crane electrical equipment, substations and industrial switchgears. They can be used both for autonomous operation and as part of automated monitoring and control systems.
