Blue Sea Systems 7442 UL-489 Circuit Breaker 15A DC Flat Rocker

The Blue Sea Systems 7442 is a UL-489 certified circuit breaker designed for critical marine and military applications where regulatory compliance is mandatory. This 15-amp DC circuit breaker features magnetic hydraulic trip-free technology, providing reliable overcurrent protection for 12V, 24V, and other low-voltage DC systems up to 80 volts.

Key Features:

• UL-489 certified for use on Navy, Army, Coast Guard vessels, and commercial vessels covered under CFR 46
• Magnetic hydraulic, trip-free design prevents manual override during fault conditions
• 15-amp continuous rating with 10,000A interrupt capacity
• Flat rocker actuator for easy panel mounting and operation
• Single pole configuration for simple circuit protection
• #10-32 screw terminals with tin-plated brass for corrosion resistance
• Rated for 80V DC maximum voltage

Ideal for applications requiring UL-489 compliance, this circuit breaker provides professional-grade protection with trip-free safety that cannot be defeated by holding the actuator. The tin-plated brass terminals ensure reliable connections in marine environments where corrosion is a concern.
