ABJ4 Series Three-phase AC Protection Relay
- product brand:Shanghai Chaoshi Electronic & Electrical Equipment Co., Ltd.
- Numéro de stand：E2G36
- product specification:88 (L)×33 (W)×68 (H) mm
- product category:--
- product introduction:The current protection functions and the voltage protection functions of ABJ4 Protection Relay can protect the voltage of the whole system and protect the current of the load. It can also protect the load end of the main circuit from current unbalance (such as current unbalance caused by contact faults of the contactor or the circuit breaker).
The current protection functions are applicable to three-phase variable-frequency load protection, if you choose a model that comes with an additional power supply.
