Why Choose the ABB E4S4000 PR123/P-LSIG 4000A Air Circuit Breaker Moving Part?
The ABB E4S4000 PR123/P-LSIG, order code 1SDA056815R1, is a high-performance SACE Emax moving part for a withdrawable air circuit breaker designed for switching and protection in high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax E4S series, this four-pole configuration combines a 4000 A rated uninterrupted current with the advanced PR123/P-LSIG R4000 electronic protection release.
The PR123/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. These LSIG functions provide comprehensive protection for switchboards, busbars, feeders and connected equipment while supporting selective protection in demanding industrial and infrastructure distribution networks.
Designed as the moving portion of a four-pole withdrawable E4S circuit breaker, the 1SDA056815R1 is intended for use with the corresponding ABB SACE Emax fixed part installed in the switchboard. The E4S 4000 platform is rated at 4000 A with an ultimate short-circuit breaking capacity of 75 kA at 415 V AC and a short-time withstand current of 75 kA for 1 s.
