Blue Sea Systems 7182 285 Series 40A Surface Mount DC Circuit Breaker

The Blue Sea Systems 7182 is a medium-duty surface mount circuit breaker designed for 40 Ampere DC loads requiring both switching capability and circuit protection. This thermal circuit breaker features trip-free technology that prevents the breaker from being held closed after a trip condition occurs, ensuring reliable protection for your electrical system.

Key Features:

• 40 Amp rating with 48V DC maximum voltage capacity
• Type III manual reset with integrated switchable operation
• Trip-free design prevents override after fault detection
• Visible reset lever clearly indicates open/closed status
• High 3,000 Amp interrupt rating for robust fault protection
• Rectangular surface mount design with 1/4"-28 stud terminals
• Compact dimensions: 2.9"H x 1.9"W x 1.78"D
• Drop-in replacement for 185 Series circuit breakers

This 285 Series breaker is ideal for marine, RV, and mobile power applications where reliable overcurrent protection and manual switching control are essential. The thermal protection mechanism responds to sustained overload conditions while the high interrupt rating safely handles short circuit faults. The surface mount configuration simplifies installation on panels and bulkheads.
