The DC Modular Remote Battery Switch 48 V / 350 A is a smart high current magnetic latching contactor, that can handle continuous DC currents of up to 350 Amps. The Remote Battery Switch 48 V / 350 A can easily be installed in an engine room or battery compartment while being controlled from a more convenient location by a small panel mounted switch. But the Switch can for instance also be controlled by a battery monitor or Lithium battery, as a discharge/overcharge protection.
- Smart terminal design allows dual mirrored cable lug connections
- Stainless steel studs, washers and nuts for optimal corrosion resistance
- Local Open and Close buttons on top, to manually override the switch state
- Robust transparent covers with breakouts to allow wire access from any direction

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