Description
Protect your car haulers electrical architecture and eliminate parasitic power draw with the genuine 9003E-B Blue Sea Systems Battery Switch (Cottrell Part # 109474 / 109474). This heavy-duty master disconnect switch is specifically engineered for self-contained hydraulic power units (HPUs) and multi-car transport trailers.
Built to handle massive electrical loads, this ignition-protected battery switch allows fleet operators to completely cut off battery power when the trailer is idle, preventing unexpected battery drain and maximizing the lifespan of your power cells. The rugged, impact-resistant enclosure is hermetically sealed against moisture, heavy road grime, grease, and extreme temperature fluctuations. Featuring a highly tactile, ergonomic control dial, it ensures crisp, positive switching between the ON and OFF positions even when wearing thick work gloves. The compact footprint makes it a direct-fit replacement for standard trailer electrical enclosures and battery boxes.
Ensure your trailers hydraulic decks and loading systems have reliable starting power when you hit the road. Replace worn, corroded, or failing electrical switches with a commercial-grade safety disconnect built to withstand daily heavy-duty towing abuse.
