The Blue Sea 285-Series Surface Mount Circuit Breaker is a versatile and reliable solution for protecting DC electrical systems in demanding environments. Designed to function as both a circuit breaker and a switch, it supports loads from 25A to 120A, making it ideal for a wide range of applications including marine vessels, RVs, off-grid solar systems, and vehicle-based power setups. This breaker is engineered for safety, space efficiency, and long-term durability—even in wet or corrosive conditions.

How it works (in simple terms): If too much power flows through your system, this breaker automatically shuts off the connection to prevent damage—just like a safety switch. You can then flip the lever to reset it once the issue is fixed.

Key Features:

• Water-Resistant Construction: Engineered with corrosion-resistant materials and a sealed manual reset lever, ideal for use in marine, RV, or outdoor installations.
• Thermal Circuit Protection: Medium-duty protection from 25A to 120A, safeguarding against overloads and short circuits in your DC system.
• Trip-Free Design: Breaker cannot be held closed after a fault—ensuring safe, automatic power disconnection.
• Manual Reset Lever: Clear, visible lever makes it easy to identify a tripped breaker and reset it manually on-site.
• Surface Mount Installation: Mounts directly to flat surfaces such as electrical panels or bulkheads with no need for extra housing.
• Drop-In Replacement: Matches the footprint of Blue Sea’s 185-Series, allowing for fast upgrades with minimal installation changes.
