General
WCM7(E)L series current protective circuit breaker (Auto-reclosed) is the new type product researched and developed at recent years. WCM7(E) is one integrate type, multi-function, adjustable over-current, thermagnetic earth leakage circuit breaker. It applies at low voltage grid of three-phase-four-line nertral direct grounding (TT grounding system), to offer indirect contact protection to personal contact danger, and to protect the line, grounding fault, over-current, short circuit etc.
