WCM1L series residual current protection moulded case
circuit breaker (RCCB for short) is one new breaker
researched and developed by advanced international
design and manufacture technology of the company. The
rated insulation voltage 800V, applies AC50Hz, rated
operation voltage 400V, rated operation current upto 800A
for infrequent switch of the line and infrequent start of the
motor. RCCB has protection functions to overload, short
circuit and under voltage, to protect the line and power
device from deamge, also make protection to the fire
caused by grounding fault at long time that undetected
under over current.
RCCB is divided into type M (higher breaking), and type
H (very high breaking), has features of smal volume,
high breaking, short flashover, vibration resistance, etc.
