Overview

The Blue Sea Systems 8173 is an A-Series double blank mounting panel for A-Series double pole toggle circuit breakers. It is made from 1/8" aluminum 5052 alloy and measures 2.63" wide by 3.75" high, giving you a compact mounting point that fits this breaker format without looking out of place on a marine electrical panel.

The slate gray finish matches standard Blue Sea panel color, and the face accepts Blue Sea Systems large format panel labels so circuit identification stays clear and easy to read. This matters on boats where a breaker panel may be checked quickly underway, at the dock, or during service work.

Key features

• Built for A-Series double pole toggle circuit breakers, so the panel opening matches this breaker style rather than a general switch cutout.
• 1/8" aluminum 5052 alloy gives the breaker a rigid mounting surface suited to marine panel work.
• Slate gray finish blends with standard Blue Sea panel color for a consistent panel face.
• Accepts Blue Sea Systems large format panel labels for straightforward circuit marking.
• Compact 2.63" x 3.75" face size helps when panel space is limited.
• Panel layout accepts Blue Sea Systems LED indicators used for functions such as power on or reverse polarity indication.

Compatibility and fit

This panel is intended for installations that use the A-Series double pole toggle breaker footprint. It makes the most sense when the rest of the electrical system already uses Blue Sea A-Series toggle breakers and matching labels. It is not a universal trim plate for unrelated breaker or switch openings.

Installation and setup

For refits and service work, this panel gives you a neat faceplate for mounting a breaker on a vertical surface where a clean breaker presentation matters. Before cutting or replacing a panel section, check the available face space against the 2.63" by 3.75" dimensions and leave room for labels and any indicator lights used in the panel layout.

This is a practical choice for boats that need an added breaker position or a replacement mounting panel that keeps the electrical panel easy to read and easy to service.
