Blue Sea Systems 7185 285 Series 70A DC Circuit Breaker Surface Mount

The Blue Sea Systems 7185 is a 285 Series surface mount DC circuit breaker designed to provide medium-duty circuit protection for demanding marine and automotive electrical systems. Rated for 70 amperes, this thermal circuit breaker combines both switching and overcurrent protection in a single, compact unit rated for up to 48V DC operation.

Key Features:

• 70 ampere rating with 3000 amp interrupt capacity for robust overcurrent protection
• Trip-free design prevents the breaker from being held closed after tripping, ensuring reliable protection
• Visible reset lever clearly indicates open/tripped condition for easy status monitoring
• Type III manual reset with switchable operation provides both circuit protection and on/off control
• Short-circuit lockout prevents reset when fault condition persists
• Rectangular surface mount design for versatile installation options
• Drop-in replacement for legacy 185 Series circuit breakers
• Dual 1/4"-28 threaded studs for secure cable connections

Specifications: 48V DC maximum operating voltage, thermal trip mechanism, compact dimensions of 2.9"H x 1.9"W x 1.78"D. Ideal for marine, RV, and automotive applications requiring switchable circuit protection for high-current DC loads including inverters, windlasses, thrusters, and other critical electrical equipment.
