Description
Keep your car carriers auxiliary power and hydraulic dump circuits performing reliably with the genuine Cottrell SPNO Power Solenoid (Part # 5276). Sourced directly through Cottrells premium OEM parts distribution network, this single-pole, normally open magnetic switch is engineered specifically to handle high-amperage current demands for 12V DC electric motor assemblies on multi-car auto transport trailers.
Manufactured with high-conductivity copper terminals and a corrosion-resistant yellow-zinc dichromate plated housing, the 5276 solenoid is built to survive relentless over-the-road field vibrations, heavy road spray, salt, and intense grease exposure. Its robust mechanical design ensures clean electrical switching under load, preventing terminal welding and electrical contact arcing that can leave your trailer decks stranded without power. The integrated, heavy-duty mounting bracket provides a secure drop-in fit for standard trailer electrical enclosures and battery compartments.
Eliminate sluggish motor starts and protect your trailers primary electrical architecture from power surges. When performing fleet maintenance, always ensure your auxiliary electrical batteries are fully disconnected and the master power switch is turned off prior to installing the replacement relay.
