## Overview

The Blue Sea Systems 7183 285 Series Thermal Circuit Breaker is a robust 50A, 48V DC surface-mount device that integrates switching and circuit protection. Featuring a trip-free mechanism, ignition protection, and water resistance, it’s engineered for demanding marine and industrial applications. Designed as a direct replacement for the 185 series, it offers easy installation with terminal caps and studs, backed by a 5-year warranty for reliable, long-term performance.

## Description

Circuit protection and switch combined in a single medium duty breaker. Ideal for windlass and electric winch applications, these surface mounted medium duty circuit breakers function as a switch, but also provide tailored circuit protection. A visible lever shows when the breaker has tripped and cannot be held in the ON position if a fault is detected. Ignition protected and water resistant, they can be installed almost anywhere; including the engine room of gasoline powered boats. Connected terminal caps protect terminals from accidental contact and help to prevent cross current shorts. Terminal studs are located on the face of the circuit breaker for easy installation.
