1.General
LCT contactors are available in two versions. Contactors without manually-operated and Contactors with manually-operated. The breadth of the LCT contactor range satisfies most application cases. LCT contactors can be combined with auxiliary control, protection and indic ation functions.
LCT series AC contactor (hereinafter referred to as the household appliances control a contactor) is used for remote switch on and off without a sense of feeling or low load, resistance furnace, household appliances and similar low load, motor and other household.The main contactor is used in AC 50Hz/60Hz, rated voltage to 400V, rated current of power system to 100A, AC-1, AC-7a (in no sense or sense of low load, resistance furnace, household appliances and similar low load) categories, long distance switch and control circuit.Contactor is not used for breaking short circuit current, so it is necessary to choose suitable short circuit protection electrical equipment.
