The Blue Sea Systems 285 Series DC Circuit Breaker (panel mount) provides medium-duty DC circuit protection with an integrated switching function—ideal for marine and off-grid power distribution where both switching and overcurrent protection are needed. It features a visible reset lever, is “trip-free” for safer operation, and is designed for installations where ignition protection and water resistance are important.

- “Trip-free” design: cannot be held closed after trip.
- Visible reset lever shows the open (tripped) condition.
- Drop-in replacement for 185-Series circuit breakers (per manufacturer information).
- Maximum operating voltage: 48 volts DC.
- Meets SAE J1171 external ignition protection requirements (per provided description details).
- IP67-protected against immersion up to 1 meter for 30 minutes (per provided description details).
Intended Use
- 12V/24V/48V DC marine electrical systems

Parts Desk Insights
Best Use Case: Use this breaker for DC feeder or branch protection in a distribution panel where you need a breaker that also serves as a manual switching device, with clear trip indication.
Common Issues: If nuisance trips occur, confirm the wiring gauge and load type (especially inductive/inrush loads). During replacement, verify the breaker style matches the existing 185-Series panel footprint and that the mating surfaces and protective cover/gasket arrangement are maintained for splash/immersion resistance.
