Blue Sea 7058 25A Push Button Thermal with Quick Connect Terminals

The Blue Sea Systems 7058 25A Push Button Thermal with Quick Connect Terminals is a compact circuit protection device engineered for continuous-duty marine electrical systems. This 25-amp thermal breaker combines manual reset capability with ignition-protected design, making it safe for installation on gasoline-powered boats where fuel vapor ignition hazards demand extra safety margins. The quick-connect terminals eliminate the need for traditional crimped connections, reducing installation time and potential contact corrosion in salt-air environments.

The trip-free design is critical for marine applications—it cannot be held in the "ON" position during fault current conditions, ensuring automatic shutdown if a short circuit or overload occurs. Unlike switches that might be forced closed during an electrical emergency, this thermal breaker physically prevents operator override, a requirement for safety-critical circuits on vessels. The push-button reset mechanism allows straightforward reactivation once the fault is cleared, without requiring replacement cartridges or external reset devices. At 0.3 lbs and measuring just 3 × 1 × 5 inches, the unit fits seamlessly into Blue Sea Systems' waterproof circuit breaker panels and main battery distribution panels.

This breaker is built for weekend cruisers and serious offshore anglers alike—any boat operator running 12V or 24V DC electrical systems with moderate continuous loads. The 25-amp rating suits mid-range circuits: navigation electronics, cabin lighting, auxiliary pump protection, or bilge pump backup feeds. Installation in Blue Sea Systems' pre-engineered panels ensures compatibility and proper bus integration, while the ignition-protected housing meets U.S. Coast Guard and American Boat & Yacht Council standards for gasoline vessel wiring. Experienced boaters recognize Blue Sea Systems' thermal breakers as the industry standard for reliability in demanding marine environments where corrosion, vibration, and repeated thermal cycling demand proven engineering.
