12V Continuous Duty Solenoid Relay – 4 Post, 300A Peak

Keep your equipment working with a 12V continuous duty solenoid relay built for sustained electrical loads below 100 amps and peak loads up to 300 amps.

This four-post solenoid uses a low-current control circuit to switch power to a higher-current load. It’s a replacement option for compatible hot water pressure washer burner circuits, electric motors, and other 12V equipment requiring continuous duty operation.

Why choose this solenoid?

• Continuous duty operation: For applications drawing less than 100A continuously.

• 300A peak capacity: Handles brief current surges when equipment starts.

• Four-terminal design: Two large power studs and two small control terminals.

• SPST switching: Simple on/off control of a single power circuit.

• Nickel-plated finish: Helps resist surface corrosion.

• Straight mounting bracket: Mounting holes spaced 2-13/64 inches on center.
