ABB HC800
Product Introduction
The ABB HC800 is a high-performance molded case circuit breaker designed for critical power distribution applications requiring reliable protection up to 800A. Part of ABB’s comprehensive circuit breaker portfolio, the HC800 combines advanced protection features with robust construction for industrial and commercial electrical systems.
Engineered for demanding environments, the ABB HC800 features a current-limiting design that provides superior protection against short-circuit currents. Its compact footprint and flexible mounting options make it ideal for space-constrained installations, while the advanced trip unit ensures precise coordination with downstream protective devices.
Core Advantages and Technical Highlights
Advanced protection technology:
The ABB HC800 incorporates a PR122/P-LSI electronic trip unit with adjustable protection settings for overload (L), short-circuit (S), and instantaneous (I) protection. The ground fault protection (optional) provides enhanced system safety.
Robust construction:
Featuring a thermoplastic glass-fiber reinforced housing, the HC800 withstands mechanical stress and electrical arcing. The current-limiting design reduces let-through energy during faults, protecting downstream equipment.
