Pollak Battery Disconnect Switches
When it comes to protecting vehicles from electrical fires, preventing theft, and ensuring safe storage, Pollak has been engineering reliable solutions since 1909. The brand's battery disconnect switches represent over a century of expertise in heavy-duty electrical components, specifically designed for trucks, RVs, marine vessels, and agricultural equipment where robust battery management is critical.
Pollak Master Disconnect Switch Engineering
Pollak's master disconnect switches are designed for 12 VDC vehicles to disconnect all circuitry to reduce possibility of theft or accidental electrical fires, available in keyed or lever versions, with or without indexing pins, and various sizes of terminal studs. The brand offers both 2-pole and 4-pole configurations, with the latter specifically engineered for applications requiring alternator or generator field circuit protection. These 4-pole designs are designed to break alternator generator circuit prior to battery circuit disconnect.
Built for Demanding Conditions
What distinguishes Pollak battery disconnect switches in commercial and recreational vehicle applications is their construction quality. Models like the 51-902EP feature a current rating of 180 DC Amp and voltage rating of 6-36 VDC, handling everything from standard 12V systems to 24V heavy-duty truck applications. The individually sealed contacts found in Pollak's EP series provide superior protection against moisture and contaminants, critical for marine and off-road environments. Die-cast housings sealed with O-rings at the base and mounting stem create a weatherproof barrier that extends service life even in harsh underhood conditions.
Keyed and Lever Options for Every Application
Pollak understands that different applications demand different control methods. Their keyed switches provide security features ideal for fleet management and theft prevention, requiring one of the included keys for operation. Lever-operated models offer quick, tool-free disconnection for routine maintenance and seasonal storage. Both styles feature large 3/8" copper terminal studs for reliable high-amperage connections and accommodate panel thicknesses up to 1/4", making installation straightforward across diverse mounting scenarios.
A Legacy of Heavy-Duty Expertise
Pollak is a certified ISO9001/QS9000 manufacturer that earned Q1 preferred status at Ford, General Motors' Mark of Excellence, Chrysler's Gold Pentastar, Navistar V, and similar rankings with PACCAR, Freightliner, John Deere, Case, Caterpillar, and other respected OEMs. This OE-level quality translates directly to the aftermarket, where professional technicians and DIY enthusiasts alike rely on Pollak battery disconnect switches for applications ranging from work truck fleets to recreational vehicle winterization. Whether protecting a commercial vehicle during extended downtime or providing an extra layer of security for marine batteries, Pollak's master disconnect switches deliver the rugged reliability that heavy-duty applications demand.
