Blue Sea 2138 Medium Duty Push Button Reset-Only - 15A

The Blue Sea 2138 Medium Duty Push Button Reset-Only 15A circuit breaker is engineered for marine and boating applications where reliable electrical protection is non-negotiable. Built to withstand the harsh saltwater environment and constant vibration found aboard vessels, this weatherproof breaker handles main, branch, or dedicated 24-hour circuit protection with equal confidence. Whether you're running critical navigation systems, cabin lighting, or auxiliary power distribution, this compact unit delivers the dependability serious boaters demand.

The push-to-reset design eliminates the need for external manual override levers, simplifying panel installation and reducing exposed mechanical components vulnerable to corrosion and accidental damage. Its trip-free mechanism automatically disconnects the circuit under fault conditions—even if someone holds the button—ensuring fail-safe protection that won't be overridden by operator error. The compact form factor enables high-density circuit configurations, allowing more protection in tighter panel spaces without sacrificing accessibility or serviceability, a critical advantage on boats where electrical panels are typically mounted in cramped engine rooms or cabin areas.

This breaker is ideal for freshwater and saltwater vessels of all sizes—from center console fishing boats to cruising sailboats and commercial workboats. The 15A rating suits typical cabin circuits, deck lighting, and auxiliary loads common on recreational and professional vessels. Installation requires only standard panel cutout space; compatibility with existing Blue Sea Systems panels and industry-standard marine electrical enclosures makes retrofits or upgrades straightforward. Weight just 0.2 lbs and measuring 3 x 2 x 4 inches, it integrates seamlessly into modern and legacy marine electrical systems alike.
