Detailed description

The Blue Sea Systems L-Series 150A 12/24V solenoid, part number 7765, is designed for switching medium-current DC loads in marine and 12V/24V onboard systems. It provides a remote control solution for demanding applications.

Design and performance

This SPST (single-pole single-throw) normally open solenoid is notable for its continuous duty capability. It handles a continuous rated current of 150A with 2 AWG cable at 50°C ambient, an intermittent current of 225A (5 minutes), and an inrush current of 600A (30 seconds). Its nominal voltage is 12V/24V DC, with a control circuit accepting voltages from 9V to 36V DC. Coil current draw is 0.13A at 12V and 0.07A at 24V, minimizing heat generation and coil circuit power consumption.

Integration and robustness

The 7765 features hermetically sealed contacts, ensuring protection against harsh marine environments and enhanced durability. It is CE certified and has IP67 protection, guaranteeing waterproofing against immersion up to 1 meter for 30 minutes. It is activated remotely via a low-ampere ON-OFF switch (sold separately). Compared to the 9012 model in the same series, which offers a continuous capacity of 250A and higher inrush capabilities (900A for 30 seconds), the 7765 is suited for loads under 150A, such as DC subpanels, bow thrusters, windlasses, or moderate power inverters. The terminals are M8 studs, accepting 5/16" lugs, with a maximum tightening torque of 10 Nm.

« Technical analysis of the Blue Sea L-Series 150A DC power management solenoid »

Blue Sea Systems' L-Series 150A solenoid provides a reliable solution for managing medium-power circuits aboard recreational and professional vessels. Its role sits between a simple relay and a motorized battery switch, offering remote control without manual locking. It is particularly suitable for applications where manual isolation is already provided elsewhere in the circuit, or for specific loads requiring centralized activation/deactivation without direct intervention on the solenoid.

We recommend the 7765 for powering small to medium bow thrusters, windlasses, inverters, or secondary battery banks. Its low-ampere control circuit, which does not require external coil suppression, simplifies wiring and integration into existing electrical panels. For continuous loads exceeding 150A, such as more powerful thrusters or high-capacity inverter/charger systems, the 9012 model from the same series is preferable, offering 250A continuous rating and ignition protection per ISO 8846 and SAE J1171, along with UL 508 certification.

Installation follows standard practices for this component type, with M8 studs for power connections and 22 AWG control wiring. The extended operating temperature range (-40°C to +85°C) and IP67 rating ensure consistent performance even in unconditioned technical environments or salt-spray exposure. This solenoid is a pragmatic choice for optimizing DC power management without excessive complexity.

Frequently Asked Questions

Need help? Contact us

What is the primary function of the Blue Sea Systems L-Series 150A solenoid?

This solenoid is designed for remote switching of medium-current DC loads in marine and 12V/24V onboard systems. It allows circuit control without direct manual intervention on the device.

What is the nominal operating voltage of this solenoid?

The L-Series 150A solenoid is designed to operate with nominal voltage systems of 12V or 24V DC.

What is the DC current capacity of this solenoid?

It handles a nominal continuous current of 150 amperes (A) when used with a 2 AWG cable at an ambient temperature of 50°C.

Is the solenoid normally open or normally closed?

This solenoid is SPST (single-pole single-throw) and is normally open (Normally Open). This means the main circuit is open (disconnected) when the coil is not powered.

What is the current draw of the control circuit (coil)?

The DC current draw of the control circuit is 0.13A at 12V and 0.07A at 24V. This low consumption minimizes coil heating and power draw.

Is this solenoid waterproof and resistant to marine environments?

Yes, the L-Series 150A solenoid features hermetically sealed contacts and has IP67 protection. This ensures waterproofing against immersion up to 1 meter for 30 minutes, making it suitable for harsh marine environments.

What are the operating temperatures for this solenoid?

The solenoid is designed to operate within a temperature range of –40°C to +85°C.

What is the difference between a solenoid and a remote battery switch?

A solenoid like the L-Series 150A is an electronic switch without direct manual control, used for circuits where manual battery disconnection is already provided elsewhere. A remote battery switch, on the other hand, is a solenoid or relay with a manual control switch, allowing switching even if the control circuit is compromised, and offering a lock function for maintenance.

What are the regulatory certifications for this product?

The L-Series 150A solenoid is CE certified, confirming compliance with European safety, health, and environmental protection standards.

What is the weight of this solenoid?

The weight of the L-Series 150A solenoid is 0.43 kg (0.95 lb).

How is this solenoid activated?

The solenoid is activated remotely via a low-amp ON-OFF switch, which is sold separately. It has no direct manual control on the device itself.

What types of terminals are used for the main connections?

Main connections are made via M8 studs, which accept 5/16-inch lugs.

What is the maximum recommended tightening torque for terminal studs?

The maximum recommended tightening torque for terminal studs is 10 Nm (90 in-lb).

What types of mounting screws are required to secure the solenoid?

The solenoid can be mounted using #10 or M5 screws.

What is the recommended torque for mounting screws?

The recommended torque for mounting screws is 1.7 to 3.4 Nm (15 to 30 in-lb).

What type of wire is recommended for connecting the coil circuit?

For connecting the coil circuit, use tinned wire, 22 AWG gauge.

What are the physical dimensions of this solenoid?

The main dimensions of the solenoid are:

Maximum width: 58.2 mm (2.29 in)Maximum height (excluding terminals): 68.3 mm (2.69 in)Maximum depth: 80.8 mm (3.18 in)Distance between mounting hole centers: 73.7 mm (2.90 in)

For which applications is this solenoid suitable?

This solenoid is suitable for applications requiring switching of loads under 150A. This includes DC subpanels, bow thrusters, windlasses, or moderate-power inverters.
