Blue Sea 2142 Medium Duty Push Button Reset-Only - 50A

The Blue Sea 2142 Medium Duty Push Button Reset-Only circuit breaker is a 50-amp marine electrical protection device engineered for reliable overcurrent protection in harsh saltwater environments. Designed for gasoline-powered vessels, this push-to-reset breaker serves as main, branch, or 24-hour circuit protection with a compact footprint that enables high-density electrical configurations in tight engine compartments and cabin spaces.

The 50A rating handles substantial electrical loads while the trip-free design ensures the breaker cannot be manually held in the ON position during a fault condition—a critical safety feature that prevents bypassing of protection during electrical emergencies. Captive star lock washers prevent loosening from vibration, a persistent problem in high-vibration marine environments. The weatherproof construction withstands constant spray, humidity, and temperature cycling without corroding or losing function. Blue Sea Systems' ignition protection certification makes this breaker safe for installation aboard gasoline-powered boats where spark-free operation is a legal and safety requirement.

This breaker is ideal for anglers and cruising boaters who demand reliable DC electrical systems for trolling motors, navigation electronics, galley equipment, and auxiliary power. Whether outfitting a freshwater bass boat, a coastal fishing platform, or an extended-range cruising vessel, the 2142 provides the compact, proven protection that keeps critical systems running when they matter most. Its push-button reset design offers intuitive operation—no switches to learn, just press to restore power after a fault clears.
