Blue Sea 7183 - 285-Series Circuit Breaker, Surface Mount 50A

The Blue Sea 7183 - 285-Series Circuit Breaker, Surface Mount 50A is designed for use in harsh marine environments where reliable protection is essential. This breaker serves as a drop-in replacement for the 185-Series Circuit Breakers and is equipped with a visible reset lever that clearly shows when the breaker is in the open condition. It is ignition protected, meeting SAE J1171 external ignition protection standards, ensuring it is safe for installation on gasoline-powered boats. The breaker combines both switching and circuit protection functions in one unit, providing efficient and secure protection for your electrical systems.

This surface-mount circuit breaker utilizes a thermally responsive bi-metal blade to deliver reliable protection against overloads and short circuits. It features a "Trip Free" design, which ensures the breaker cannot be held closed after it has tripped, preventing potential damage from continued operation under fault conditions. With a maximum voltage rating of 48V DC and an interrupt capacity of 3000A at 48V, this breaker offers robust protection. It operates within a temperature range of -40°C to 85°C, making it suitable for various marine applications. However, it is not recommended for use in applications with high inrush currents.
