Rated insulation voltage of 800v, ??S Scope is ideal for terrestrial and marine production used for AC 50hz, rated working voltage 690v and below, (cm1-63 for 400v), rated current to the circuit 800a for frequency conversion and motor protection (cm1-800 no motor protection) purposes. Breaker with overload, short circuit and under voltage protection, to protect equipment from damage and power lines. Breaker according to its rated limit short-circuit breaking capacity (icu) level, divided into c-type (basic type), l-type (standard), m-type (high breaking type), h-type (high breaking type) four. The circuit breaker has a small, breaking high, arcing short (some of the specifications zero arcing), anti-vibration characteristics, and the nuclear industry have passed the test conditions (1e-level) test and ship conditions, can become the only domestic products nuclear industrial base products, but is ideal for the production of land and marine use
