Imtra SPA-10600 12 Volt Solenoid 300 Amp Continuous Duty

Imtra SPA-10600 12 Volt Solenoid 300 Amp Continuous Duty

The Imtra SPA10600 is a compact, continuous duty 12 volt solenoid used to switch power to a single windlass motor in one direction, either up or down. It is commonly paired with Muir and Lofrans windlasses and is suitable for other DC loads that require reliable, high current switching.

This simple, single direction solenoid is ideal inside a custom control panel, locker mounted switchgear, or behind up and down switches at the helm. Use one SPA-10600 for a dedicated up or down function, or two solenoids for full up and down control when you are not using a prewired reversing control box.

Key Features

• Continuous duty 12 V DC solenoid for anchor windlass and general DC switching.
• Controls one windlass motor operation in a single direction at a time (up or down).
• Compatible with many Muir and Lofrans DC windlasses that use external solenoids.
• Compact footprint for tight anchor lockers, consoles, and switch panels.
• Heavy duty insulated studs for secure battery and motor cable connections.
• Can be triggered from low amp footswitches, rocker switches, or remote panels.
• Simple, field serviceable design that works in custom windlass switchgear layouts.

SPA-10600 Technical Specifications

Typical Applications

Always confirm that your windlass motor current draw and duty cycle are within the solenoid ratings and that the system is wired according to the windlass manufacturer instructions.

Installation Tips

• Verify that your windlass and DC system operate on 12 V before ordering. This solenoid is for 12 V systems only.
• Mount the SPA-10600 in a dry, protected area close to the battery feed or windlass to minimize voltage drop.
• Use tinned marine grade cable sized for the maximum current and run length recommended by your windlass manufacturer.
• Protect the circuit with a properly sized main breaker or fuse located as close to the battery as practical.
• Use low amp control wiring from footswitches, rocker switches, or panels to the solenoid coil terminals.
• Label wiring clearly so future troubleshooting and service is straightforward.

Maintenance Guidelines

• Inspect mounting hardware and cable terminals at least once per season for looseness or corrosion.
• Clean any green or white corrosion on terminals and replace damaged lugs or heat shrink as needed.
• Check that all cables are supported and not rubbing on sharp edges or moving hardware.
• If the solenoid chatters, fails to pull in, or runs hot, inspect battery voltage, cable size, and control wiring before operating the windlass again.
• In saltwater environments, consider a light coating of corrosion inhibitor on external terminals after connections are completed.

Frequently Asked Questions

How many SPA-10600 solenoids do I need for my windlass?
For simple up only or down only operation you typically use one SPA-10600. For full up and down control you normally use two SPA-10600 solenoids or a prewired reversing control box. Always check the wiring diagram supplied with your windlass.

Can I use this solenoid on a 24 V system?
No. The SPA-10600 is designed for 12 V DC systems. For 24 V windlasses use the appropriate 24 V rated solenoid or control box specified by Imtra or the windlass manufacturer.

Is the SPA-10600 a reversing solenoid?
No. It is a single direction solenoid that switches power in one direction only. Reversing is accomplished by using two solenoids or a dedicated reversing contactor or control box.

Can I mount the solenoid in the chain locker?
Many installations place the solenoid close to the windlass to keep high current cables short. Choose a location that is as dry and protected as practical and follow the windlass instructions. For very wet locations a watertight control box is usually a better choice.
