## Overview

The Blue Sea Systems 7035 187 Series is a 50A medium duty circuit breaker and switch combo designed for marine use. It offers a drop-in replacement for 185-series breakers, features a visible reset lever for quick status checks, and is ignition-protected for gasoline-powered boats. Its weather-resistant housing ensures durability in harsh environments, making it ideal for windlass and electric winch applications while simplifying installation and wiring.

## 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.

*by N***M on 22 April 2025*

Blue sea genuine product It’s really good Save yourself some problems and order this right from the start i had put a cheap one and it was still letting current through when off . The cheap ones will also often only do 50% of what they are rated for so not saving anything by buying cheap products this is the right brand if you want to do it properly.
