Blue Sea 187-Series Circuit Breaker Surface Mount Series.

Blue Sea Systems 187-Series Surface Mount Circuit Breakers

Blue Sea Systems 187-Series surface mount circuit breakers combine switching and circuit protection in a single device, engineered to provide durable and reliable performance for 25 to 200 Amp loads. These breakers feature a clear, single lever operation and a "trip free" design that prevents the breaker from being held in the "ON" position during a fault current condition. They are ignition protected per SAE J1171, making them safe for installation aboard gasoline-powered boats, and weatherproof to withstand marine environments.
