Why Choose the ABB E4S4000 PR122/P-LSIG Air Circuit Breaker?

The ABB 1SDA056805R1 is a high-performance SACE Emax E4S air circuit breaker moving part designed for switching and protection in high-current low-voltage electrical distribution systems. Identified as E4S4000 PR122/P-LSIG, this three-pole withdrawable circuit breaker combines a 4000 A rated current with ABB's PR122/P-LSIG electronic overcurrent release for comprehensive circuit protection.

As part of the ABB SACE Emax / New Emax range, the E4S4000 is engineered for demanding industrial, commercial and infrastructure power distribution applications. Its S short-circuit performance level provides an ultimate and service short-circuit breaking capacity of 75 kA at 400 V AC, with a rated short-time withstand current of 75 kA for 1 s and 3 s. Its withdrawable moving-part construction supports efficient inspection, servicing and replacement when installed with the corresponding fixed part.

The integrated PR122/P-LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. With a rated operational voltage of 690 V AC, three-pole configuration and 4000 A rated uninterrupted current, the 1SDA056805R1 is well suited to main incoming, feeder and distribution protection duties in substantial low-voltage installations.

Reliable Protection for High-Current Power Distribution

Air circuit breakers such as the ABB E4S4000 provide switching and protection for high-current low-voltage distribution systems. The circuit breaker interrupts abnormal current conditions to help protect cables, busbars, switchgear and connected equipment against damage caused by overloads, short circuits and ground faults.

The PR122/P-LSIG electronic release provides long-time overload, short-time, instantaneous short-circuit and ground-fault protection. Combined with the E4S's 75 kA short-circuit performance and withdrawable construction, this makes the 1SDA056805R1 suitable for major distribution boards, switchboards and industrial installations where comprehensive protection, high current capacity and serviceability are required.

Typical Applications

  • Main incoming circuit protection in high-current low-voltage switchboards.
  • Industrial power distribution systems.
  • Transformer and generator secondary distribution systems.
  • Protection of high-current distribution feeders and busbar systems.
  • Large commercial and infrastructure electrical installations.
  • Manufacturing plants and process facilities.
  • High-current switchgear and electrical distribution assemblies.
