Pollak 52-312-01 Starter Solenoid - 12V 100A Continuous Duty Grounded Switch

High-Performance Power Management with Simplified Grounding

The Pollak 52-312-01 Starter Solenoid provides consistent, heavy-duty power control for 12V DC systems. Specifically designed for continuous duty, this solenoid is built to stay energized for long periods without failure, making it an essential component for battery charging circuits, hydraulic lifts, winches, and auxiliary power systems in heavy trucks.

The standout feature of the 52-312-01 is its internally grounded housing. By grounding directly through the mounting bracket to the vehicle chassis, it simplifies your wiring harness and reduces installation time. Encased in a rugged, zinc-plated steel housing, this solenoid is engineered to endure the vibrations and environmental stresses of the trucking and construction industries.

Key Features & Benefits:

• Continuous Duty Performance: Rated for constant "on" operation, unlike standard intermittent starter solenoids.

• Internally Grounded: Streamlined 3-terminal design (2 large, 1 small) grounds through the metal case to the frame.

• 100 Amp Rating: Reliable handling of 100 Amps continuous current and up to 600 Amps surge.

• Corrosion Resistant: Zinc-plated steel housing protects internal components from moisture and debris.

• Versatile Application: Ideal for RVs, tow trucks, snow plows, and industrial equipment.

• Secure Mounting: Features a flat mounting bracket for stable, permanent installation.
