Cole Hersee Continuous Duty Solenoid - 200A - 12V

The Cole Hersee Continuous Duty Solenoid – 200A – 12V is a heavy-duty remote-acting switch engineered for demanding electrical applications where reliable, repetitive switching is critical. This solenoid serves as the backbone for starter motors, winches, and industrial control systems that require instantaneous electromagnetic engagement. Designed for users who depend on consistent performance in marine, automotive, and tactical equipment environments, this Cole Hersee unit delivers the switching capacity needed when standard relays fall short.

Operating at 12 volts with a 200-ampere continuous duty rating, this solenoid utilizes proven electromagnetic coil design to create instantaneous contact closure with minimal voltage drop. The continuous duty specification means it can sustain full 200A load indefinitely without thermal shutdown, unlike intermittent-duty alternatives that require cooling cycles. The compact 3 x 2 x 5-inch footprint and 0.9-pound weight allow flexible mounting in tight engine bays, vehicle frames, and equipment enclosures while maintaining robust internal construction that resists vibration, corrosion, and electrical stress common in field conditions.

Operators managing 12-volt DC systems—from overland vehicles and military support equipment to marine auxiliary power and emergency backup circuits—benefit most from this solenoid's reliability and load capacity. Installation requires direct positive and negative connections to the 12V power source and load circuit; ensure wiring gauge matches the 200A specification to prevent voltage loss and heat buildup. The Cole Hersee construction is compatible with standard solenoid mounting brackets and integrates seamlessly into existing relay circuits, making it an ideal upgrade or replacement for applications demanding sustained high-amperage switching performance.
