1SDA060769R1 ABB E3S-A 800 PR122/P-LI 800 A 3P Withdrawable Air Circuit Breaker

Why Choose the ABB E3S-A 800 PR122/P-LI In=800A 3p W MP?

The ABB E3S-A 800 PR122/P-LI In=800A 3p W MP, order code 1SDA060769R1, is a SACE Emax E3S-A withdrawable air circuit breaker moving part designed for demanding industrial low-voltage power distribution. It combines an 800 A rated current with ABB's advanced PR122/P-LI electronic overcurrent release for dependable overload and instantaneous short-circuit protection.

This breaker features a three-pole withdrawable configuration, identified by ABB as a moving part (MP), for installation with a compatible E3 fixed part. The withdrawable design enables the breaker to be racked out for inspection, maintenance or replacement while the fixed part remains installed within the switchboard, improving serviceability in critical electrical distribution systems.

The E3S-A 08 platform provides a short-circuit current capability of 65 kA at 480 V AC and a short-time current capability of 65 kA. Together with its PR122/P electronic release and UL configuration, the 1SDA060769R1 provides a robust protection solution for industrial switchboards, main distribution systems and high-fault-level feeder applications.

Serviceable Electronic Protection for Industrial Switchgear

The ABB E3S-A platform combines the robust switching architecture of the SACE Emax family with electronic protection for demanding industrial distribution systems. As a withdrawable moving part, the 1SDA060769R1 interfaces with a compatible E3 fixed part, enabling the circuit breaker to be withdrawn from the switchboard for inspection, servicing or replacement.

Its PR122/P-LI electronic release provides long-time protection against sustained overloads together with instantaneous protection against severe short-circuit faults. Combined with an 800 A rated current, 65 kA short-circuit current capability at 480 V AC and withdrawable construction, the breaker provides a strong combination of protection performance, fault handling and maintainability.
