Standard Battery Switch For any vehicle that needs to use two batteries where one battery is used for starting the engine, while the other is used to power auxiliary loads. This is a common situation in trucks, boats, RVs, police and rescue vehicles, and in ambulances or fire equipment. A selector switch allows use of the first battery, the second battery, or both batteries simultaneously. This provides back-up starting power in an emergency. Features: These switches combine the functions of Battery Selector and Master Disconnect Switches to give four battery power options: Power cut off at the source Power On, Battery 2 Power On, Battery 1 Power On, both Batteries Battery selector switches provide a positive battery disconnect, which has many advantages: It gives a reliable shutdown of power during maintenance The version with the key protects against theft of the vehicle, when unattended It helps protect against electrical fires, when the vehicle is not in use, and minimizes battery drain Specifications: Rating: 500A intermittent, 310A continuous, 6-36V DC Electrical ratings on UL labels are conservative. Electrical Ratings Labeled UL 707B Use with either alternators or generators Make before break design permits operation through the three On positions with the engines running. Engines should always be shut down before turning to Off Heavy-Duty Construction Vaporproof, weather-, dust- and corrosion-resistant Durable, fracture-resistant high temperature plastic case, knob and insulator Switches conform to USCG section 183.410 for ignition protection Heavy duty copper stud terminals, with brass hexnuts Can be surface mounted, or installed through a 3 5/16" diameter hole in the panel Dimensions: Flange: 6" (152.4mm) diameter, overall height 2 5/8" (66.7mm) Terminals: 3 copper studs, 3/8" (9.5mm) diameter

Pro Installer 400A EZ-Mount Dual Bank Control Battery Switch - MC10 Another addition to our multi award winning Pro Installer EZ Mount range, the innovative Dual Bank Control switch is like 3 switches in one, House, Start, and Emergency Parallel. Offering 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.

Remote Operated Battery Switch w/Optical Sensor 500A 12/24V The MD range of battery switches allow you to install the battery switch very close to the battery, to remotely manage the increased electrical loads found on today's boats. This reduces cable lengths and sizes, providing significant savings in expense and weight of copper battery cable. They are ideal for remote isolation of bow and stern thrusters. The 720-MDO has been enhanced to offer easy standard installation, or advanced options capable of switching different voltage circuits from the main supply (for example: a 48 volt bow thruster with a 24 volt house supply). The optical sensor uses the same easy connection for standard installation and gives you the ability to control different voltage circuits such as 36 or 48 volts. It can be used to switch positive or negative lines and the main contacts can be isolated from the control circuit allowing operation via another battery source. This optical sensor also has low stand-by current draw (<5mA). Remote operation Battery switch can be mounted alongside battery, reducing cable lengths and cable sizes. (Large cost and weight saving in copper cables) Reduced installation labor due to shorter battery cable runs Manual override option to meet CE/ABYC requirements LED status identification for remote control switch Same capacities/specifications and mounting options as standard BEP battery switches Uses interchangeable labeling system (Item # 713 or 715) Specifications: LxWxH: 4" x 4" x 4.33" Rating (A DC) Cont: 500 Rating (A DC) Inter: 700 Rating (A DC) Crank: 2500 Voltage (V DC): 9.5-32 Function: On/Off Stud Size: 2x (1/2"/12mm) WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.

Pro Installer 400A Double Pole Battery Switch - MC10 A powerful new generation battery switch with outstanding performance and features for both the installer and end user. Three mounting options: surface, rear panel, and front panel mounting, plus optimized cable access makes installation a breeze. Pro Installer switches set the new benchmark with outstanding ergonomics, intuitive look/feel, and are engineered from the finest materials to withstand the harsh marine environment. Same industry standard mounting with On/Off operation. Used where positive and negative supplies must be isolated at the same time. SAFETY NOTE: BEP does not recommend this for switching house and start battery systems at the same time, for safety reasons. You may need to isolate your engine battery in an emergency, but not your house battery which typically powers the communications Specifications Mounting: Surface, Rear or Front Voltage: 48v DC (for 12-48v systems) Rating: 400 Cont / 600 Inter / 1500 Crank Dims: 3.85" x 3.85" x 3.62" Operation: On/Off Stud: 4x 10 mm (3.8") WARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.
