125A 250A Moulded Case Earth Leakage Circuit Breaker ELCB MCCB 3
1, the use of the new circuit breaker body structure, not only the
volume of products compared with similar products have been
significantly reduced, but also greatly improve the breaking
2, the power supply can be automatically after power off, the power
supply automatically detects the operating parameters of the
circuit to detect the normal closing automatically.
3, the circuit parameters show high precision, accurate action,
while the residual current value of a wide range of options, and
optional automatic tracking function, the other has no alarm
4, with the real-time circuit parameters and fault display
function, and can accurately record the time of failure, for
5, the electric backup protection mechanism, to ensure reliable
6, three point positioning rail type electric mechanism of the
unique design, product operation is stable and reliable.
7, the three directory and digital control, indicator lights,
buttons, easy to operate, intuitive and clear.
8, the product has many functions, intelligent, communication and

Matters needing attention
1, is strictly prohibited to wet hand operation residual current
protection circuit breaker, or electric shock accident.
2, at the same time touch the electric shock accident between the
two does not play a protective role.
3, the product of the "leakage alarm" exit is enabled, residual
current protection circuit breaker function (i.e.: when the line
residual current circuit breaker, no action, only issued a warning
signal), therefore "alarm" function must be approved by the related
departments before opening.
4, the series of residual current protection circuit breaker can
not directly on the person from the role of electric shock
protection! Directly used for leakage breaker personal electric
shock protection please use the residual current less than 30mA in
5, when the power equipment fault type power outage maintenance,
must be "manual / automatic" knob to "manual", a manual operating
handle brake, the fault does not exclude or maintenance tasks have
been completed, no compulsory manual closing, in order to avoid a
sudden power supply caused unnecessary losses.
6, the residual current protection circuit breaker outlet line can
not be repeated grounding line, the protection of any line can not
be mixed with other lines.
7, "a key off" residual current protection circuit breaker with
plastic shell circuit breaker basic function (overload and short
circuit), please be careful.
8, the residual current circuit breaker protection in normal use,
according to the GB 13955 "residual current action protection
device installation and operation" requirements, to attempt to test
and record button.
