1SDA060929R1 ABB E1N-A 800 PR122/P-LI 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060929R1 E1N-A 800 Air Circuit Breaker?

The ABB 1SDA060929R1 is a dependable E1N-A 800 withdrawable air circuit breaker (ACB) moving part designed for protection and switching in low-voltage power distribution systems. As part of the proven ABB SACE Emax series, this three-pole breaker combines an 800 A rated current with the PR122/P electronic overcurrent release for reliable protection in industrial and commercial electrical installations.

The breaker is equipped with an ABB PR122/P electronic trip unit with LI protection functions, providing long-time overload and instantaneous short-circuit protection. Its withdrawable moving-part configuration supports convenient isolation, inspection and servicing when installed with a compatible SACE Emax fixed part, making it particularly suitable for maintainable switchboard installations.

The E1N-A 800 configuration uses an R800 overcurrent release with an Im 12000 A designation. This UL three-pole moving part is also fitted with four auxiliary contacts and open/closed position indication, supporting status monitoring and integration within low-voltage switchgear systems.
