- product brand:Shanghai Circuit Shield Electronic & Electrical Equipment Co., Ltd.
- Numéro de stand：E2G36
- product specification:61 (L)×20.5 (W)×73 (H)mm
- product category:Refrigeration Equipment-Components for refrigerating systems and plants -Miscellaneous components for refrigerating systems and plants
- product introduction:Features
◆ Designed based on the Chinese Invention Patent held by the company, this is a product
developed for the purpose of simplifying control circuits;
◆ Simple control circuit; compact size; clear fault display; convenient installation; high
reliability;
◆ Shell made of nylon; push-type wiring method; high temperature resistance.
◆ Contact forms: J represents make contacts used for tripping circuit breakers;
K represents make contacts used for tripping leakage protectors;
L represents make contacts used on load end of contactors.
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.
