MADE IN GERMANY
The Bender RCMA420-D-1 (B94043001) is a residual current monitor for a vessel’s control and electrical supervision plant, where it watches circuits for AC and DC residual current. Its response value covers 30 mA to 500 mA across a frequency range of 0 to 2 kHz, and it carries relay contacts rated AC 250 V 5 A. The device accepts either an AC 16-72 V or a DC 9.6-94 V supply and consumes 2.5 VA. It runs software D242 V1.10 and was made in Germany. The unit is offered in used condition for switchboard and control panel circuits that need residual current supervision.
