Blue Sea Systems L-Series Solenoid Switch, 150A, 12/24V DC, SPST Normally Open, Continuous Duty

Overview

The Blue Sea Systems 7765 is an L-Series solenoid switch rated for continuous duty and used for remote switching of medium-amp DC loads on 12V and 24V boats. It uses a 9-36V DC control circuit, carries 150A continuously, and is built as an SPST normally open solenoid with hermetically sealed contacts.

This is the kind of switch you use when the control point needs to be away from the load, such as a DC subpanel, thruster, windlass, or inverter feed. Continuous coil draw stays low at 0.13A on 12V systems and 0.07A on 24V systems, with 3.8A used when changing state, so it works well in circuits that may stay energized for long periods.

Key features

• 150A continuous rating, 225A for 5 minutes, and 600A cranking for 30 seconds
• 9-36V DC control circuit for 12V and 24V nominal systems
• SPST normally open contact form for remote ON/OFF control of DC loads
• Hermetically sealed contacts and no external coil suppression required
• Low continuous coil draw of 0.13A at 12V and 0.07A at 24V
• M8 terminal studs accept 5/16 in cable terminals, with 22 AWG tinned wire for the control connection
• Mounting holes sized for #10 or M5 fasteners
• Works with the Blue Sea Systems 8230 remote ON-OFF switch, sold separately

Compatibility and fit

The 7765 is for remote electrical control rather than a local manual disconnect at the device. Because the contact form is normally open, the circuit closes only when the solenoid is energized. That suits installations where a manual battery switch is already placed elsewhere in the system and the load needs its own remote switching point.

For cable fit, the main studs are M8 and take 5/16 in ring terminals. The control side uses 22 AWG tinned leads. The mounting footprint spans 3.18 in across the ears and 2.90 in front to back, which helps when space is tight near a panel, locker, or auxiliary load.

Installation and setup

This switch is commonly mounted close to the load circuit or distribution point so the high-current cable run stays short while the control switch is placed at the helm, nav station, or another convenient location. The built-in coil control circuit keeps heat and amperage draw down, which matters when the switch may remain closed for extended periods.

Check cable size, overcurrent protection, and terminal fit against the connected load and the M8 stud hardware. The unit mounts with #10 or M5 screws, so it is straightforward to secure on a bulkhead or panel surface that can handle normal onboard vibration.

Use on board

This model is a good match for boats that need remote switching for equipment that draws more current than a small dash switch should carry. It fits well on cruising boats, fishing boats, and service craft where the switching point and the load are in different parts of the vessel.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
