Description
The DC Modular Battery Protect Relay has the same capabilities as the Remote Battery Switch. It is a smart high current magnetic latching contactor, that can handle continuous DC currents of up to 500 Amps.
Whereas the Remote Battery Switch is mainly used as a locally or externally controlled battery load switch, the Modular Battery Protect Relay has a number of additional features. Most importantly, it can protect your battery without the need for an external measurement and control device.
