## Overview

The Blue Sea Systems 7183 285 Series Thermal Circuit Breaker is a 50A, 48V DC surface-mount breaker designed as a drop-in replacement for 185-series models. It features a visible reset lever for quick status checks, an ignition-protected design compliant with SAE J1171 for safe use in gasoline-powered boats, and a weather-resistant housing that ensures durability in harsh marine environments. Combining switch and circuit breaker functions, it simplifies wiring and saves space, making it ideal for windlass and electric winch applications.

## 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.

## Features

- DROP‑IN REPLACEMENT FOR 185‑SERIES BREAKERS: Simplifies upgrades and repairs by matching existing mounting patterns for quick installation
- VISIBLE RESET LEVER: Allows you to instantly confirm breaker status, improving safety and troubleshooting efficiency on board
- IGNITION‑PROTECTED DESIGN: Safe for use in gasoline‑powered boats, meeting SAE J1171 external ignition protection requirements for added peace of mind
- WEATHER‑RESISTANT HOUSING: Ensures reliable performance in harsh marine environments, protecting your electrical system from moisture and corrosion
- SWITCH + CIRCUIT BREAKER COMBINATION: Reduces component count by combining switching and overcurrent protection into one unit, saving space and simplifying wiring
