Pollak 52-307-01 Starter Solenoid - 12V 100A Continuous Duty Insulated Switch

Heavy-Duty Power Control for Demanding Applications

The Pollak 52-307-01 Starter Solenoid is an industrial-grade, continuous duty switch engineered for applications requiring constant electrical flow. Unlike intermittent solenoids, this unit is designed to remain "on" for extended periods, making it the perfect choice for winch systems, hydraulic pumps, emergency vehicles, and heavy-duty truck electrical systems.

Built for longevity, it features a high-quality plated steel housing and an insulated design, ensuring the solenoid is protected from the elements and safe for use in diverse mounting environments. The Single Pole Single Throw (SPST) circuitry and normally open contacts provide reliable, consistent performance under high-current loads.

Key Features & Benefits:

• Continuous Duty Rating: Engineered to stay energized for long durations without overheating.

• 100 Amp Capacity: Handles 100 Amps of continuous DC current and up to 600 Amps in-rush (surge).
