Model ABJ2-□2WJ/K - Phase Sequence Protector for Trip Circuit Breakers
- product brand:Shanghai Circuit Shield Electronic & Electrical Equipment Co., Ltd.
- Numéro de stand：E2G36
- product specification:
- product category:Refrigeration Equipment-Components for refrigerating systems and plants-Miscellaneous components for refrigerating systems and plants
- product introduction:Functions
Protection functions: Phase sequence, Dynamic phase loss, Static phase loss, Voltage unbalance, loss of zero line protection (only for three-phase four-wire circuit)
The indicator lights for phase loss or voltage unbalance take priority over the one for phase dislocation. Phase loss should be troubleshooted first when a power failure happens.
Contact forms: J represents normally-open contacts (used for trip circuit breakers); K represents normally-open contacts (used for trip leakage protectors).
Technical Parameters
