Blue Sea 7287 C-Series Triple Pole Circuit Breaker - 50A

The Blue Sea 7287 C-Series Triple Pole Circuit Breaker – 50A is a marine-grade electrical protection device engineered to manage main AC circuit loads on 120/240-volt systems. Built to meet ABYC (American Boat and Yacht Council) standards for marine electrical safety, this triple-pole breaker delivers 5,000-ampere interrupt capacity and is designed for applications where robust, code-compliant main protection is non-negotiable.

The triple-pole configuration allows simultaneous switching of both hot lines and neutral on 240-volt AC main circuits, critical for complete circuit isolation and operator safety during maintenance or emergency shutdown. At 50 amps, this breaker handles substantial loads typical of vessel power systems, offshore installations, or dual-voltage shore power applications. The white toggle switch provides tactile feedback and clear on/off indication in high-vibration or low-light environments. Compact dimensions (4 × 2 × 5 inches) and lightweight construction (0.3 lbs) allow straightforward integration into existing panel layouts without significant rewiring or panel modifications.

This breaker serves marine electrical systems, offshore platforms, RV power distribution, and any 240-volt AC installation requiring ABYC-compliant main protection. Operators managing vessel electrical systems, shore-power infrastructure, or multi-phase shore installations depend on reliable circuit protection to prevent cascading electrical failures. The Blue Sea 7287 fills that role with proven reliability across saltwater and freshwater environments where corrosion resistance and operational consistency matter.

Blue Sea Systems is recognized within the marine industry for electrical components meeting stringent maritime standards. The C-Series line represents mid-range capacity breakers positioned between single-pole residential applications and industrial three-phase systems, making them the practical choice for vessels and specialized marine installations requiring ABYC compliance without oversized equipment.
