Product Description
STID-B Residual current Circuit Breaker(RCCB B model) using recharge station
General:
STID-B RCCB B model is worked on type A and in addition for smooth DC residual currents, residual DC currents that may results from rectifying circuits and high frequency AC residual currents.It protects in the event of contunuous fault current on three phase networks. It usually is used in the field of Recharging Station, Medical Apparatus and Instruments, Controllers and Variable Speed Drives, Batter Charges and Inverters(DC)...STID-B complys with IEC/EN61008 and IEC/EN62423 standards.
Roduct Over View:
1. Provide protection against earth fault/leakage current and function of isolation
2. High short-circuit current withstand capacity3. Applicable to terminal and pin/fork type busbar connection
5. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
6. Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
