Why Choose the ABB E2H-A 800 PR121/P-LSI 1SDA061079R1 Air Circuit Breaker?
The ABB E2H-A 800 PR121/P-LSI, order code 1SDA061079R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB New Emax E2 series, it combines an 800 A rated current with high short-circuit performance and electronic overcurrent protection for industrial, commercial and infrastructure power-distribution applications.
This three-pole circuit breaker is equipped with an ABB PR121/P-LSI R800 electronic overcurrent release, providing long-time, short-time and instantaneous protection functions. These LSI functions help safeguard electrical installations against sustained overloads and short-circuit conditions while supporting coordinated protection across low-voltage distribution networks.
With a rated current of 800 A, a three-pole fixed configuration and rear horizontal terminals, the E2H-A 800 provides a robust solution for permanent installation within compatible electrical switchboards. The E2H-A frame offers a short-circuit current rating of 85 kA at 480 V and a short-time current rating of 65 kA, making it particularly suitable for installations with demanding fault-current requirements.
