Overview
M7C series residual current operated circuit breaker mainly used in three phase four wire circuit with AC 50Hz or 60Hz, rated voltage 440V, rated current to 800; except the protection of overload or short-circuit, it also has the protection of residual current , over voltage, under voltage, the phase-lacking, faulted neutral line(optional) and so on.The product with high level of performance is easy to use, and it can be used to display the current voltage, current, residual current, trip reason and phase intuitively.You can choose to have a RS485 communication interface, transfer of circuit breaker opening or closing state, the trip analysis, the voltage and current of each phase and the residual current circuit breaker's data; also can remotely set the protection action value and action time,can enable or disable the various protection functions.
All technical indexes are in conformity with GB14048.2-2008,GB6829-2008,Q/GDW11196-2014,Q/GDW11020-2013,CCC;and have passed the authoritative testing by Chinese EPRI of conventional function, residual current and special environment action characteristics, lightning protection module, communication function, scholte wave functions and technical parameters .
Functions
