Pollak 52-315 Starter Solenoid - 12V 100A Continuous Duty Insulated Plastic Housing

Corrosion-Resistant Power Control for Demanding Environments

The Pollak 52-315 Starter Solenoid is a high-performance continuous duty switch designed for long-term electrical reliability. While many solenoids feature metal casings, the 52-315 is engineered with a rugged molded plastic (Bakelite) housing. This construction offers superior resistance to moisture and corrosion, making it an excellent choice for marine applications, salt-exposed trucks, and industrial equipment.

This unit is rated for continuous duty, meaning it is designed to stay energized for extended periods without overheating—ideal for battery isolators, winches, and auxiliary power management. Its insulated design provides two dedicated small terminals for the coil circuit, ensuring the solenoid remains electrically isolated from the mounting surface.

Key Features & Benefits:

• Continuous Duty Cycles: Built to handle constant electrical loads in 12V DC systems.

• Non-Corrosive Housing: The durable plastic/Bakelite body prevents rust and electrical shorts to the casing.

• Insulated Circuitry: 4-terminal design (2 large studs, 2 small studs) for precise wiring and safety.

• 100 Amp Reliability: Manages 100 Amps of continuous current with a high in-rush capacity for starting.

• Versatile Applications: Perfect for boat ignition systems, RV battery banks, and heavy-duty agricultural machinery.

• Standards Compliant: Designed to meet or exceed OEM specifications for heavy-duty electrical components.
