Blue Sea 187-Series 100 Amp Circuit Breaker Surface Mount

The Blue Sea 187-Series 100 Amp Circuit Breaker Surface Mount is a combined switching and protection device engineered for demanding electrical systems in tactical, military, and marine applications. Built for environments where reliability under stress is non-negotiable, this circuit breaker eliminates the need for separate switch and breaker installations, consolidating critical power management into a single, compact unit. Whether you're outfitting a mobile command post, armored vehicle, emergency response vehicle, or off-grid tactical base, this breaker handles the high-amperage demands of modern operational equipment.

This surface-mount breaker features Blue Sea Systems' proven "Trip Free" design, which prevents the lever from being held in the ON position during a fault condition—a critical safety feature that protects both personnel and sensitive equipment from overcurrent damage. The single-lever operation delivers intuitive, gloved-hand accessible switching without ambiguity, eliminating user error during high-stress situations. The 100-amp rating accommodates power-hungry loads common in tactical platforms: communications arrays, lighting systems, auxiliary power distribution, and integrated sensor networks. The robust construction withstands the vibration, thermal cycling, and environmental extremes inherent to field deployment, while the surface-mount configuration allows flexible installation in existing panel systems without requiring complete rewiring.

Law enforcement mobile units, military field operations, and emergency management personnel rely on this breaker for power system integrity during extended deployments. The 187-Series model integrates seamlessly into 12V and 24V DC systems common in vehicle and portable installations, though verification with your specific electrical architecture is essential before installation. Surface mounting makes it ideal for retrofit applications where internal panel space is limited. Operators and technicians benefit from the straightforward operation and reliable fault protection, ensuring critical systems remain online during normal operation while isolating circuits instantly when overcurrent occurs—a balance that field experience has proven essential for mission success.
