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

Due to the magnetic latch construction, the WP-MBP draws virtually no current in the ON or OFF state. A current draw only exists shortly (500 ms max.) when changing the state of the contact. |

Using the top side buttons, one can manually override the switch state as commanded through the control wires. A dedicated ‘ON / Standby’ button also allows the user to put the WP-MBP in a standby mode with open contact. In this mode any command from the control wires and/or manual override buttons are ignored. |
