Why Choose the ABB E3H2000PR122/P-LI Air Circuit Breaker?
The ABB E3H2000PR122/P-LI is a high-performance four-pole air circuit breaker (ACB) designed for reliable protection, switching and isolation in demanding low-voltage electrical distribution systems. Part of the established ABB SACE Emax E3H series, this fixed circuit breaker combines a 2000 A rated uninterrupted current with the PR122/P-LI electronic overcurrent release.
The PR122/P-LI R2000 electronic trip unit provides long-time overload and instantaneous short-circuit protection. These LI protection functions help safeguard conductors, switchgear and connected equipment against sustained overcurrents and severe short circuits, while the E3H high-breaking-capacity platform is suited to distribution systems with substantial prospective fault currents.
The ABB 1SDA056443R1 is supplied as a four-pole fixed E3H 2000 circuit breaker with rear horizontal terminals. Its 2000 A current rating, high fault-interruption capability, electronic PR122/P protection and four auxiliary contacts with open/closed position indication make it particularly suitable for main switchboards and high-current industrial power-distribution applications.
