Application
CJC20 series self-holding efficient Contactor  can keep coil without current when holding suck.  energy-saving, no noise &  won't burn out excitation coilis.  suitable for using in the circuits up to rated voltage 690V AC 50/60Hz, rated current up to 630A,

It's mainly applied to connect & breaking equipments.
1.Main current leakage protection place & match with current-leakage implus relay.
2.Distribution switch part with timing electricity shuntdown
3.reactive power compensation capacitor control panel 
These places don't need contactor interrupt when electricity failure, admit self-distribute when electricity supply. similar like auto-switch.

Combined with the auxiliary contact block, timer delay & machine interlocking device ect, it becomes the delay Contactor, star-delta starter. With the thermal relay, it's combined into the electromagnetic starter.
The product confirm to IEC60947-4-1.
