Blue Sea 187-Series 80 Amp Circuit Breaker Surface Mount

Blue Sea Systems 187-Series 80A Circuit Breaker

The Blue Sea Systems 187-Series Circuit Breaker, part number 7142-BSS, combines circuit switching and overcurrent protection in one compact surface-mount device. Rated for systems up to 48V DC, this thermally responsive bi-metal blade circuit breaker provides dependable protection for marine electrical systems and other demanding DC applications. Its waterproof construction and ignition-protected design make it suitable for installation aboard gasoline-powered boats while meeting SAE J1171 external ignition protection requirements.

The clear, single-lever operation provides straightforward control and visible trip-status indication. The lever can be positioned vertically or horizontally, making it easy to identify the breaker condition at a glance. Its trip-free design prevents the lever from being held in the ON position during a fault-current condition, supporting safer operation. Recessed mounting holes create a clean finished appearance, while generous clearance around the terminal studs accommodates heavy-gauge wire lugs. Robust 5/16-inch M8 terminals support high-torque connections, with a recommended terminal stud torque of 75 inch-pounds.

Designed for surface mounting, the Blue Sea Systems 7142-BSS delivers an 80A rating and an interrupt capacity of 5,000A at 12V. Do not use this circuit breaker as a switch where high inrush currents are expected. This product carries a California Proposition 65 warning: Cancer and Reproductive Harm—www.P65Warnings.ca.gov.
