Detailed description

The BEP set of 3 275A single-pole battery switches is designed for reliable isolation of battery circuits in marine and demanding environments. Each switch provides ignition protection and can handle a continuous load of 275 amperes DC, with an intermittent current of 455 amperes for 5 minutes and a starting current of 1250 amperes for 10 seconds. The maximum supported nominal voltage is 48 volts DC.

Design and Technical Specifications

These battery switches stand out for their construction in fiber-reinforced molded plastics resistant to high temperatures, ensuring durability in harsh conditions. The terminals are equipped with two 10 mm (3/8 inch) tinned copper studs with nuts, facilitating connections for cables up to 1/0. Each switch measures approximately 69 x 69 x 75 mm (2.75 x 2.75 x 3 inches). Activation is performed by rotating the knob 45° for on/off positions. The design allows for surface or flush mounting via a 52 mm (2.1 inch) hole. The patented Contour locking system allows switches to be used individually or assembled for an integrated installation. This design complies with ABYC specifications and has been independently tested to UL 1107 standards at 110% of specified ratings.

Features and Integration

Safety is enhanced by a removable control knob in the 45° counterclockwise position, preventing unintended activation during maintenance. The knob also features an interchangeable labeling system for various applications. Three removable side plates provide easy access for cables, while a rear cover isolates terminals against short circuits, ensuring ABYC compliance. The "Easy Fit" design simplifies installation by replacing most European lever-and-post switches and can be flush-mounted in panels up to 19 mm (3/4 inch) thick using a removable threaded ring. While these switches are manual solutions, BEP, as a member of the Navico group, also offers CZone digital switching systems, providing options for more complex electrical architectures. This set of battery switches represents a robust and certified solution for managing onboard power, comparable to other single-pole switches on the market but distinguished by its certifications and patented locking system.

Expert opinion

« Technical analysis of the BEP 275A unipolar battery disconnect switch set »

This set of three BEP 275A single-pole battery isolators is a fundamental solution for electrical management on vessels, particularly those with multiple battery banks (starting, service, auxiliary) or systems requiring quick and secure isolation. Its primary use case is segmenting and securing power supply, essential for maintenance, preventing deep discharges, or emergency disconnection. Its spark-proof design is a major advantage for engine compartments where flammable vapors may be present, a criterion often required by safety standards and marine insurers.

In terms of installation, the "Easy Fit" design and the option to mount surface or flush simplify integration on existing panels or during new builds. The Contour locking system is particularly relevant for creating a clean, modular control panel, allowing multiple switches to be aligned consistently, for example one per battery or major circuit. The 10 mm studs and easy cable access up to 1/0 gauge simplify wiring. The removable knob provides a dual advantage: it ensures anti-theft security and prevents accidental activation during maintenance operations. This type of battery isolator is a wise choice for recreational boaters and professionals seeking a manual, robust, and certified electrical isolation solution without the complexity or cost of a digital management system.

Frequently Asked Questions

Need help? Contact us

What is the primary function of a single-pole battery switch?

A single-pole battery switch is designed to reliably isolate a battery’s circuits, allowing you to cut power to a system or specific load. This is essential for safety, maintenance, and preventing battery discharge.

What is the continuous nominal current rating each battery switch can handle?

Each battery switch in this kit is rated for continuous DC loads up to 275 amps.

What is the maximum voltage supported by these battery switches?

The maximum nominal voltage supported by these battery isolators is 48 volts DC. They are also suitable for 12V and 24V systems.

What materials are the BEP battery disconnect switches made of?

These battery isolators are made from fiber-reinforced molded plastics and are heat-resistant, ensuring durability in harsh conditions, particularly in marine environments.

What is the Contour locking system and what is it used for?

The Contour locking system, patented by BEP, allows individual switches to be used or assembled together for a grouped and organized installation.

Do these battery isolators provide ignition protection?

Yes, each switch in this set is designed to provide ignition protection, which is critical for safety in environments where flammable gases may be present, such as on boats.

How many battery isolators are included in this set?

This product is a kit that includes 3 single-pole battery isolators.
