Pollak 52-330 Starter Solenoid - 12V 100 Amp Continuous Duty S.P.D.T. Dual Circuit Switch

Versatile Circuit Toggling for Heavy-Duty Power Management

The Pollak 52-330 Starter Solenoid is a specialized, high-performance 12V continuous duty switch designed for applications that require a changeover between two circuits. Featuring S.P.D.T. (Single Pole, Double Throw) circuitry, this solenoid acts as a powerful relay to toggle power between a Normally Open (N.O.) and a Normally Closed (N.C.) contact, providing unique flexibility for complex electrical setups.

Engineered for Constant Reliability

Built by Pollak for the demanding environments of heavy-duty trucking, marine, and industrial use, the 52-330 is rated for a 100 Amp continuous load. Its 6-terminal insulated design ensures that you can safely manage auxiliary power systems, battery crossovers, or emergency lighting without the risk of overheating during long-cycle operations.

Key Features & Benefits:

• S.P.D.T. Circuitry: Single Pole, Double Throw configuration allows for "Changeover" switching between two circuits.

• Continuous Duty Rating: Engineered for 100 Amps of constant power at 12V DC (600 Amp in-rush).

• 6-Terminal Configuration: Includes two large studs for power and four smaller studs for specialized control and grounding.

• Normally Open & Normally Closed: Provides one active circuit when the solenoid is engaged and another when it is at rest.

• Ruggedized Housing: Insulated construction designed to withstand vibration and moisture in harsh vehicle environments.
