1SDA060961R1 ABB E1N-A 1200 PR122/P-LI 1200 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB 1SDA060961R1 E1N-A 1200 Air Circuit Breaker?

The ABB 1SDA060961R1 is a robust E1N-A 1200 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 a 1200 A rated current with the PR122/P electronic overcurrent release for dependable 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 configuration allows the breaker moving part to be isolated from a compatible fixed part or cradle, supporting efficient inspection, servicing and replacement in maintainable low-voltage switchgear.

With its E1N-A performance level, three-pole construction and 1200 A current rating, the 1SDA060961R1 is suited to substantial incoming, feeder and distribution duties. The service-friendly withdrawable arrangement makes it particularly useful where continuity, maintainability and reliable electronic circuit protection are important.
