Battery master switch

Battery switches for boats, yachts and vehicles

The battery switch isolates the battery system from the onboard network. It prevents deep discharge during lay-up, makes maintenance work safe and allows a quick emergency shutdown. philippi supplies rotary and selector switches, flange switches for high currents and remote-controlled switches for 12, 24 and, depending on the model, 48 V.

In brief: The main switch switches, the main fuse protects. The two belong together; the fuse sits no more than 17.8 cm from the positive post (ABYC E-11).

The designs

  • BHM and BHS rotary switches: round, for surface, flush or panel mounting. BHM size 300 A continuous (900 A for 30 s), BHS size 350 A (1,200 A for 30 s), also double-pole.
  • BWS selector switches: switch between two batteries or connect them.
  • BH-F flange switches: for high currents from 200 A rated current, IP 67, also double-pole.
  • FHR, FBR and XD series remote-controlled switches: operated by push button, P-BUS or NMEA 2000; they can sit directly at the battery while the control point can be placed anywhere.

The ratings of the Blue Sea switches apply to 120 mm² cable and are continuous ratings in the closed position, not switching capacity. All data at a glance: Blue Sea battery switches.

Choosing the right switch

Requirement Switch
One battery, up to 300 A continuous BHM rotary switch
One battery, up to 350 A continuous BHS rotary switch
Two batteries, selectable BWS selector switch
High currents, damp location BH-F flange switch (IP 67)
Operation from the helm or via P-BUS FHR or XD remote-controlled switch

Frequently asked questions

Do I also need a main fuse?

Yes. The switch isolates but does not protect against short circuits. The main fuse sits no more than 17.8 cm from the positive post; with lithium batteries only as an SHB bolt-down fuse or Class T fuse.

Can I switch under load?

That depends on the switch. The current ratings of the rotary switches are continuous ratings in the closed position, not switching capacity. Switch off large loads before changing over.

What current rating do I need?

The switch’s continuous rating must be above the highest current in the main cable, i.e. above what all loads draw together. The short-time rating covers the inrush currents of windlasses and starters.

Are there remote-controlled battery switches?

Yes, the FHR and FBR switches and the XD series are switched electrically, for example via push button, the P-BUS system or NMEA 2000.
