Modular Battery Protect Relay 48 V / 350 A

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 350 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.

  • Smart high current magnetic latching relay, draws virtually no current in On (Close) or Off (Open) state.
  • Stainless steel studs, washers and nuts for optimal corrosion resistance
  • Robust transparent covers with breakouts to allow wire access from any direction
  • Smart terminal design allows dual mirrored cable lug connections
