BEP Marine Solenoids

BEP Marine Solenoids: Precision-Engineered for the Marine Environment

When it comes to managing high-amperage electrical loads aboard a vessel, few components are as critical — or as underappreciated — as the solenoid. BEP Marine has built its reputation on delivering electrical solutions purpose-built for the demands of life on the water, and their solenoids exemplify that commitment. These are not generic off-the-shelf relays repurposed for marine use; they are engineered from the ground up to perform where corrosion, vibration, moisture, and temperature extremes are constant challenges.

What a Marine Solenoid Actually Does

A solenoid functions as an electromagnetic relay in a DC wiring system, bridging the gap between a low-current control switch and a high-current load — think windlasses, thrusters, or winches. Rather than running expensive, heavy-gauge cable all the way from a battery bank to a remote control switch, a solenoid allows a lightweight control wire to do the switching work, with the solenoid itself handling the heavy current close to the load. The result is reduced voltage drop, simpler wiring runs, and protection for the operator from high-amperage circuits.

BEP Marine's Solenoid Lineup

BEP Marine offers solenoids in several configurations to suit different onboard applications:

• Continuous Duty Solenoids — Available in 65A and 85A ratings, these units are designed for applications where the solenoid must remain energized for extended periods. They feature copper contacts, a plated steel case, and copper-threaded terminals for low-resistance, corrosion-resistant connections. Both UL and CE approvals confirm their fitness for professional and recreational marine installations.
• Motor Reversing Solenoids — BEP's 75A DPDT (double-pole, double-throw) motor reversing solenoid combines two solenoids into a single compact unit, simplifying wiring and reducing component count. Rated at 75A make-and-break at 12V, it also provides dynamic braking capability for permanent magnet motors when the coils are de-energized — a valuable safety and control feature for windlass and thruster applications.

Built to BEP Marine's Engineering Standards

Every BEP Marine solenoid reflects the brand's philosophy of engineering excellence tailored to the marine world. BEP's products meet exacting performance specifications and are designed to withstand extreme conditions both at sea and on land — a standard enforced across their entire product range. The company's deep familiarity with marine installation challenges also means that details like terminal sizing, mounting hole geometry, and hardware inclusion (hex nuts and washers) are all accounted for, reducing installation time and the risk of improvised solutions that could compromise safety.

BEP Marine's solenoids also align with the broader battery management ecosystem the brand is known for, making them a natural fit alongside their switches, distribution clusters, and digital voltage sensing relays for a cohesive, thoroughly engineered electrical system.
