EGIS 285-Series 120 Amp Circuit Breaker Surface Mount

The EGIS 285-Series 120 Amp Circuit Breaker Surface Mount (Model 4703-120) is a mission-critical electrical protection device engineered for demanding tactical, military, and law enforcement vehicle installations. This surface-mount breaker serves as the primary safeguard against electrical system overload, short circuits, and component damage in mobile command vehicles, armored platforms, and tactical support rigs where power reliability directly impacts operational success. Field-proven in both domestic law enforcement and military applications, this breaker protects high-draw accessories including communications arrays, sensor packages, power distribution panels, and auxiliary lighting systems.

Rated for 120 amps of continuous protection, the EGIS 285-Series features high-visibility ON/OFF controls that allow operators to instantly isolate power in emergency situations or during system diagnostics without requiring tools or panel removal. The sealed enclosure protects internal contacts and switching mechanisms against dust, moisture, and environmental contamination—critical when operating in desert, maritime, or urban tactical environments where corrosion and debris accumulation compromise standard breakers. High-temperature rating ensures reliable performance across all installation locations, from sun-exposed engine compartments to temperature-cycling mobile command centers, while integrated terminal insulators prevent accidental contact with live terminals during maintenance or live-circuit troubleshooting.

Tactical fleet operators, mobile command unit integrators, and law enforcement vehicle technicians rely on the 285-Series for integration into distributed power architectures where redundancy and fail-safe design prevent catastrophic electrical cascade failures. Surface-mount configuration permits rapid retrofitting into existing panels or new-build installations without requiring enclosure modification, while the 120-amp rating accommodates multi-load circuits serving communications, surveillance, and auxiliary power systems simultaneously. Weighing just 0.4 lbs, this compact breaker minimizes weight penalty while maintaining robust copper termination and bistable switching reliability expected in continuous-duty tactical environments.
