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.
Operation surrounding & Installation
