Blue Sea Systems 7142BSS 187 Series 80 Amp DC Circuit Breaker Surface Mount

The Blue Sea Systems 7142BSS is an 80-amp DC circuit breaker from the 187 Series, designed for reliable overcurrent protection in marine, RV, and automotive electrical systems. This surface-mount thermal circuit breaker provides manual reset capability and switchable on/off operation for convenient control of high-current DC circuits up to 48 volts.

Key Features:

• 80-amp current rating at 48 volts DC maximum
• Thermal-type circuit protection for reliable overcurrent shutoff
• Surface mount design for easy panel or bulkhead installation
• 5/16 inch-18 stud terminals for secure wire connections
• Switchable operation with manual reset functionality
• Single-pole configuration for straightforward circuit control
• Trip-free design prevents breaker from being held in the on position during fault conditions

The 187 Series circuit breakers from Blue Sea Systems are engineered for harsh marine environments and demanding mobile applications. The thermal design provides temperature-compensated protection that responds to sustained overloads while tolerating brief inrush currents. The ergonomic toggle handle clearly indicates circuit status and allows for easy manual tripping when needed. Ideal for protecting high-draw equipment such as windlasses, bow thrusters, inverters, and other heavy-duty DC loads.
