Relying on the AC sampling technology, Digital Residual Current Transformer can monitor the residual current in power distribution circuits and thus prevent electrical fires. It also supports the standard MODBUS-RTU protocol and connects with various standard systems. Our Digital Residual Current Transformer complies with requirements of Electrical fire monitoring system----Part 2:Residual current electrical fire monitoring detectors, GB14287.2.
