An alternator field disconnect feature is standard. These heavy duty switches are rated at up to 380 amps continuous and 850 amps intermittent (see specifications). Heavy Duty Battery Selector Switch with Alternator Field Disconnect Their use of the traditional Perko bolt circle makes for easy installation, whether new or as a replacement. Perko's 8501 Series battery selector switches are among the most popular battery switches ever produced. They can also serve as an emergency main disconnect switch in the event of an electrical problem. ACRs use a relay combined with a circuit that senses when a charging source is being applied to either battery. The Perko Single Battery Disconnect Switch permits the battery to be shut off from the electrical system when the vessel is not in use. How does an ACR differ from a battery isolator Battery isolators use one-way electrical check valves called diodes that allow current to flow to, but not from, the battery. This switch provides the flexibility of selection between batteries or combined operation of both batteries in parallel for starting or charging. The Perko Dual Battery Selector Switch allows the addition of an extra battery for accessories. An optional key lock helps to prevent unauthorized use of the vessel. They allow for a quick and easy way to shut down the entire electrical system in an emergency. They help to prevent battery drain during periods of inactivity. They are used to connect or disconnect electrical devices from the electrical system. Battery disconnect switches help manage the overall use of electrical power on-board. If you have any questions or doubt about how to use, install or wire any battery switch, consult a certified marine electrician. But adding on-off switches to the circuit you can force the alternator to charge the battery you want charged. Running with a selector switch in the both position (see selector switches) may not fully charge all batteries. All switches are ignition protected.īut for boats with multiple engines and multiple batteries, using multiple on-off switches (sometimes in conjunction with a selector switch) can provide different benefits. Like all Perko products, these time-proven switches are made in the USA. The most obvious (and most common) is simply to use it to turn off your battery when in storage so that your battery does not drain as quickly and is ready to go when you are. There are many ways to use a Perko Battery On-Off Switch.
