AOW-1000

ACB

Characteristics

It mainly used to distribute the power of the main distribution cabinet, protect the circuit and power supply from overloading, undervoltage and short circuit, the harm of single-phase grounding and other faults. This kinds of circuit breaker were provided with a variety of automatic protection function, can protect Cat.B optionally and improve the reliability of power supply. Under normal conditions, it can be used for infrequent conversion of circuits.

Rated Current: 1000A~6300A
Diference1:  a、drawer type  b、fixed type
Diference2:  a、 with LCD    b、without LCD
