BEP — EZ-Mount Double Pole On-Off Battery Switch, 400 A — BEP-770-DP-EZ

BEP EZ-Mount Double Pole On-Off Battery Switch, 400 A (770-DP-EZ)

This BEP 770-DP-EZ is a double pole On/Off battery switch that isolates both the positive and negative battery terminals. It is most commonly used on metal-hulled craft, where full isolation ensures there is no risk of stray currents that may cause galvanic corrosion. The EZ-Mount design shares its interconnection height with the Pro Installer Busbar Range, so switches and busbars cluster directly together for compact installations.

Parts Desk Insights

• Best use case: Fully isolating a battery bank on a metal-hulled craft, where switching both terminals is the standard approach to protecting against stray-current galvanic corrosion.
• Most common customer mistake: Choosing a single pole switch when both terminals need isolating, or matching a switch to the engine's cranking load. Confirm the 400 A continuous, 600 A intermittent, and 1500 A cranking ratings suit the bank before ordering.
• Sizing and fitment guidance: Plan for the industry standard 3.85" x 3.85" footprint and surface mounting, confirm the 10 mm (3/8") stud size suits the battery cables, and consider the Pro Installer busbar range for compact clustering with this switch.
