TGCH1N series modular contactors are mainly used in AC 50/60Hz power circuit with a rated working voltage up to 400V, rated working current up to 63A under use category AC-7a, and rated working current up to 20A under use category AC-7b to control the household appliances and low-inductance micro-inductance loads with similar purposes, and also can be used to control the household motor loads, and in this case the control power should be reduced accordingly.
The products are used in power distribution places such as homes, hotels, apartments, shopping malls and urban lighting systems to realize automatic control functions.
Available standards: IEC/EN 61095
