Blue Sea Systems 7188 285 Series Surface Mount DC Circuit Breaker 120 Amp

The Blue Sea Systems 7188 285 Series Circuit Breaker provides reliable medium-duty circuit protection for 120-amp DC loads where both switching and overcurrent protection are required. This surface-mount breaker combines the functionality of a switch and circuit protection in a single compact device, making it ideal for marine, RV, and other 12V/24V DC applications.

Key Features:

• 120-amp rating for medium-duty DC circuit protection
• Trip-free design cannot be held closed after tripping, ensuring safe operation
• Visible reset lever clearly shows open/tripped condition at a glance
• Drop-in replacement for legacy 185-Series circuit breakers
• Surface mount configuration for easy panel installation
• Meets SAE J1171 standard for external ignition protection
• Combines manual switching and automatic circuit protection

Important: Do not use as a switch in applications where high inrush currents are expected, as this may cause premature tripping or breaker damage.

The 285 Series represents Blue Sea Systems' proven approach to marine-grade circuit protection, featuring robust construction and reliable performance in demanding electrical systems. The visible reset lever provides quick status indication, while the trip-free mechanism ensures the breaker cannot be overridden during fault conditions.
