Blue Sea 2143 Medium Duty Push Button Reset-Only - 60A

The Blue Sea 2143 Medium Duty Push Button Reset-Only 60A marine circuit breaker delivers reliable electrical protection for boats and marine vessels. Engineered specifically for saltwater environments, this 60-amp breaker combines weatherproof construction with compact design to handle main, branch, or 24-hour circuit protection in demanding marine applications where corrosion resistance and dependable fault protection are non-negotiable.

The push-to-reset operation provides manual control over circuit engagement, while the trip-free design ensures the breaker cannot be held in the ON position during a fault condition—a critical safety feature for gasoline-powered vessels where ignition protection prevents hazardous electrical events aboard the boat. The weatherproof housing meets marine standards and stands up to salt spray, moisture, and temperature cycling. Captive star lock washers deliver anti-rotation security and proper electrical connection. The compact footprint enables high-density circuit protection configurations, allowing boaters to manage multiple circuits within space-constrained electrical panels without sacrificing protection quality.

This breaker suits weekend anglers running basic cabin lighting and navigation systems as well as serious offshore operators managing complex electrical loads across multiple engine systems, fish finders, and auxiliary equipment. Whether retrofitting an older vessel or upgrading electrical infrastructure on a new build, the Blue Sea 2143 addresses the specific corrosion and reliability challenges that freshwater and saltwater boaters face. Its 60-amp rating handles substantial power demands while remaining proven across thousands of marine installations where failure is not an option.
