BEP, 772-DBC-EZ, Pro Installer 400A EZ-Mount Dual Bank Control Battery Switch - MC10Offering easy intuitive control for the boater, the Dual Bank Control switch features a unique isolated-On position which allows use of house loads and VHF radio if the engine needs to be electrically isolated, or allows the engine to be isolated during servicing while still providing power to house loads (for lighting, stereo, fridge etc). For boats or vehicles with single Engine and House battery bank, Dual Bank Control allows the use of optimized battery banks for their respective loads; an appropriately sized deep cycle bank for House loads, and thin plate starting batteries for the Engine. Further, sensitive electronics are isolated from starter motor induced voltage spikes because House and Engine loads are separated during normal operation, unlike Selector battery switches. As easy as 1, 2, 3, these revolutionary EZ Mount battery switches allow you to wire from the front for the easiest surface mounting. With their shared interconnection height, EZ-Mount battery switches 'cluster' directly with the Pro Installer Busbar Range, resulting in the fastest, most compact installations. Optimized cable access makes installation a breeze.FeaturesTested to UL1107 ignition protection, CETinned copper 10mm (3/8 inch) studsStainless steel washers and nutsFiber reinforced plastics400A Continuous / 600A 5 minutes Intermittent / 1500A 10 seconds Cranking (cable size to achieve ratings 120mm^2, 4/0, smaller cable size will reduce the Amp rating)Waterproof to IP67Same interconnection height as Pro InstallerRemovable knob allows isolation during servicing3 removable side plates for protectionIndustry standard 3.85 x 3.85 inch footprintFor surface mounting onlyEach Pro Installer battery switch is fully tested for pressure sealing, rotation force and electrically load tested4x M10 (3/8 inch) Connection StudsModule dimensions LxWxH: 98 x 98 x 93mm (3.85 x 3.85 x 3.64 inch).
