1SDA061089R1 ABB E2H-A 800 PR122/P-LI 800 A 3-Pole Withdrawable Circuit Breaker Moving Part

Why Choose the ABB 1SDA061089R1 E2H-A 800 Circuit Breaker Moving Part?

The ABB 1SDA061089R1 is a SACE Emax E2H-A moving part for an air circuit breaker designed for dependable protection and switching in demanding low-voltage power distribution systems. This configuration is rated at 800 A, uses a three-pole withdrawable moving-part design and incorporates ABB's PR122/P-LI electronic overcurrent release.

The PR122/P-LI release provides long-time and instantaneous protection, delivering LI protection against sustained overloads and severe short-circuit conditions. The R800 overcurrent release corresponds to the breaker's 800 A rated current, while this configuration is specified with an instantaneous protection value of 12,000 A.

Designed as a withdrawable SACE Emax moving part, the 1SDA061089R1 is intended for use with the appropriate compatible fixed section. It is also fitted with four auxiliary contacts and open/closed position indication, supporting status signalling and monitoring within industrial and commercial switchgear installations.
