Product overview
CHINT CJ20 three-pole AC contactor. Choose the AC-3 current and an available AC control-coil voltage; the model hint follows the exact ordinary CJ20 order record.
Technical selection summary
| Current scope | AC-3 current at AC380/400V:10,16,25,40,63,100,160,250,400,630A. These values are not the conventional thermal current Ith. |
|---|---|
| Main circuit | AC50/60Hz; rated insulation voltage690V; impulse withstand8kV per the2023.12 manufacturer manual. |
| Coil selection | AC24/36/110/220/380V where available for the selected current. Exact matched order records checked in CHINT TaileGo on2026-11-03. |
| Thermal current Ith | Models10/16/25/40/63:10/16/32/55/80A; models100/160/250/400/630:125/200/315/400/630A. |
| Coil frequency | Match the coil frequency marked on the supplied unit. Main-circuit50/60Hz is not a claim that every control coil has a universal frequency rating. |
| Dimensions and circuits | See retained model-specific outline and circuit references. Auxiliary contact arrangements and saving-power J/JZ variants require their separate exact order codes. |
Select current first; unavailable coil voltages are disabled. Only verified ordinary CJ20 records are offered here; J/JZ, tropical and special-contact versions are excluded. Photographs are series illustrations and do not identify the selected coil.
