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

50214740	Modular Battery Protect Relay 48 V / 350 A

TECHNICAL SPECIFICATIONS
Rated voltage	60 VDC
Nominal current	500 A
Cranking current (1 min.)	1000 A
Nominal make / break current	500 A (0 – 34 VDC) / 350 A (35 – 60 VDC)
Peak make / break current	1600 A (0 – 34 VDC) / 1200 A (35 – 60 VDC)

CONTROL CIRCUIT (ELECTRICAL)
Coil / supply voltage (+ VDC)	34 – 68 VDC
Coil / supply current (idle state)*	< 100 qA
Coil / supply current (state change)*	< 1.5 A
*	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.
