Cole Hersee Continuous Duty Solenoid 85 AMP - 12V

The Cole Hersee Continuous Duty Solenoid 85 AMP - 12V is a military-grade electrical switch designed for heavy-duty applications in tactical vehicles, command platforms, and field equipment where reliable power distribution is non-negotiable. Built to Cole Hersee's exacting standards, this solenoid handles the demands of continuous operation in high-stress environments where standard commercial relays fail. Law enforcement and military operators rely on this component for winches, lighting systems, cargo doors, and other mission-critical electrical loads that cannot tolerate downtime.

This 12-volt solenoid manages up to 85 amps of continuous current, with universal design and part number configurations available for loads up to 200 amps in multi-unit configurations. The design minimizes arcing and contact oxidation—two failure modes that degrade solenoid reliability in field conditions—ensuring stable performance across repeated duty cycles. A PVC-coated variant is available for applications requiring enhanced environmental sealing, protecting against corrosion, moisture intrusion, and contamination common in deployed or desert operations. The compact 4 x 3 x 7-inch form factor and 0.6-pound weight make integration straightforward in tight equipment bays without sacrificing switching capacity.

Tactical operators, vehicle technicians, and military maintenance teams benefit from the Cole Hersee solenoid's reputation for durability under extreme use. This unit is ideal for vehicle-mounted equipment, generator systems, and any 12-volt DC application requiring sustained high-amperage switching without relay chatter or contact degradation. Installation is straightforward for experienced technicians; compatibility with existing Cole Hersee harnesses and standard solenoid mounting brackets ensures minimal integration time. For teams managing fleets of tactical vehicles or forward operating equipment, standardizing on Cole Hersee components reduces spare parts overhead and simplifies troubleshooting.
