CAW1-3200/3200A fixed type series intelligent circuit breaker (hereinafter referred to as breaker) is suitable for the
circuit of AC 50/60Hz with rated voltage 400V, 690V and rated current  3200A .It is
mainly used to distribute electric energy and protect circuit and power supply equipment
from overload, under-voltage short-circuit ,and single-phase earthing .With intelligent and
selective protection functions, the breaker can improve the reliability of power supply, and
avoid unnecessary power failure . The breaker is applicable for power stations, factories ,
mines(for 690V) and modern high-building, especially for the distribution system of intelligent
building. The breaker conforms to IEC60947-2. The whole series have past CCC certification.
