Marinco 7181-BSS Blue Sea 285 Series Surface Mount Circuit Breaker 30 Amp

The Marinco 7181-BSS is a Blue Sea Systems 285-Series thermal circuit breaker designed for surface mount applications in marine DC electrical systems. This 30-amp circuit breaker provides reliable circuit protection for medium-duty loads while combining switching and circuit breaker functions into a single compact device.

Key Features:

• 30 amp rating for 12V to 48V DC systems with 3000A interrupt capacity
• Visible yellow reset lever clearly indicates open circuit condition
• Ignition protected design safe for installation aboard gasoline-powered boats
• Trip-free operation prevents breaker from being held closed after tripping
• Drop-in replacement for 185-Series circuit breakers
• Weather-resistant construction suitable for marine environments
• M6 terminal studs accept 1/4-inch ring terminals for secure wire connections
• Operating temperature range from -40°C to 85°C

This thermally responsive bi-metal blade circuit breaker meets SAE J1171 external ignition protection requirements and is ideal for main circuit protection of medium-sized battery banks. The breaker features a 50 in-lb terminal stud torque specification and should not be used as a switch for high inrush current applications such as motor starting.
