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.
