Blue Sea Systems 285 Series DC Circuit Breaker

The Blue Sea Systems 285 Series DC circuit breaker (also called a 285-Series thermal circuit breaker or marine DC breaker) gives you resettable overcurrent protection for DC circuits on boats, RVs and other 12V to 48V DC systems. It combines switching and circuit protection in a single unit. It is a drop-in replacement for 185-Series circuit breakers.

Key Features:

• Maximum 48V DC operating voltage
• Thermally responsive bi-metal blade breaker design
• Trip-free operation: the breaker cannot be held closed after it trips
• Visible reset lever shows the open condition at a glance
• Ignition protected: meets SAE J1171 external ignition protection requirements, so it is safe to install aboard gasoline-powered boats
• Weather resistant construction for marine environments
• M6 terminal studs accept 1/4" ring terminals
• Combines the switch and circuit breaker functions in one unit. Do not use it as a switch where high inrush currents are expected.

Blue Sea Systems builds its products for the demands of the harsh marine environment. The 285 Series is available in panel mount and surface mount styles, so you can choose the one that suits your installation.
