4 Poles Mccb Low Voltage Moulded Circuit Breaker Switch
Introduction
HKW1-1000 intelligent universal circuit breaker (hereinafter
referred to as circuit breaker), suitable for AC 50Hz, rated
voltage 400V
(380V), in a distribution network with a rated current of
200~1000A, it is mainly used to distribute electrical energy and
protect circuits and power equipment from
Damaged by overload, short circuit, under voltage, single-phase
grounding and other faults. Under normal conditions, it can be used
for infrequent conversion of lines,
The page can be used for infrequent starting and protection of the
motor.
The circuit breaker has a variety of intelligent protection
functions, selective protection is accurate, can improve the
reliability of power supply, avoid unnecessary
9
Blackout. The circuit breaker has isolation function, the symbol is
marked as
