Overview

The Blue Sea Systems 4111 is a 360 panel adapter that lets a push button reset-only thermal circuit breaker fit Blue Sea Systems rocker panels and new battery management panels.

It is a small but useful panel accessory when a boat uses reset-only breaker protection and the panel layout is built around Blue Sea rocker-style openings. In practical terms, it gives you a way to mount that style of breaker in a panel aperture used for magnetic circuit breaker panel components, so the breaker can be integrated into a cleaner, more consistent helm or distribution panel layout.

This part makes the most sense on refits, panel repairs, and custom 360 panel work where the breaker type and the panel opening do not naturally match. It is a fitment piece rather than a breaker itself, so the rest of the system still depends on the compatible push button reset-only circuit breaker and the panel being used.

Key features

• Adapts a push button reset-only thermal circuit breaker for use in Blue Sea Systems rocker panels and new battery management panels
• Provides a mounting method for using that breaker style in a magnetic circuit breaker panel aperture
• Useful for panel retrofits and custom 360 panel layouts where breaker protection needs to be added without changing the panel format
• Helps keep panel layouts consistent when Blue Sea panel systems are built around rocker-style module openings

Compatibility and fit

This adapter is intended for Blue Sea Systems panel applications that use rocker panels or newer battery management panels. It is matched to push button reset-only thermal circuit breakers, so fit should be checked against the breaker style already specified for the panel build.

For boat owners and installers, this is a sensible match when the panel needs reset-only branch protection for circuits that are not switched at the breaker face. It suits custom electrical work at the helm, in a cabin distribution area, or on a battery management panel where a neat factory-style layout matters as much as the protection scheme.

Installation and panel use

Because this is a panel adapter, its job is mechanical integration rather than changing circuit protection values or electrical behavior. The main check before ordering is whether your panel is a compatible Blue Sea rocker or battery management panel and whether the breaker being installed is the push button reset-only thermal type this adapter is made around.

That makes it a straightforward part for builders, yards, and owners updating an existing Blue Sea panel without reworking the full panel opening pattern. It is also useful when replacing damaged panel hardware and keeping the finished installation aligned with the rest of the panel system.
