The Blue Sea Systems 7046 187-Series thermal circuit breaker provides reliable overcurrent protection with a 120 Amp rating, ideal for marine and industrial applications. This panel-mounted device combines switching and circuit protection into a single, space-efficient unit, simplifying wiring and maintenance. Constructed with a thermoset polyester case, it meets SAE J1171 external ignition protection standards, ensuring safe operation aboard gasoline-powered boats. The clear, single-lever operation allows for quick manual reset and status checks, while the trip-free design prevents the switch from being held in the ON position during fault conditions, enhancing safety and system reliability. Waterproofing ensures durability in harsh environments, and recessed mounting holes give a clean appearance with minimal panel intrusion. The round case facilitates easy installation using a standard hole saw, and the large clearance around terminal studs accommodates heavy gauge wire lugs for secure connections. Robust 5/16-inch terminals allow for high-torque tightening, ensuring good electrical contact. The large lever can be oriented vertically or horizontally, providing visual indication of trip status at a glance, which simplifies troubleshooting and system monitoring. This circuit breaker is designed for versatile use, with an operating temperature range from -25°C to +82°C, making it suitable for a variety of demanding conditions. Its high interrupt ratings—up to 5,000 Amperes at 12 Volts DC—ensure it can safely handle large fault currents, protecting your electrical system from damage. Whether used in marine, RV, or industrial applications, this breaker offers durable, reliable circuit protection with easy installation and maintenance.
