Why Choose the ABB E4V 4000 PR122/P-LI 4000A 4P Withdrawable Air Circuit Breaker?
The ABB E4V 4000 PR122/P-LI, order code 1SDA056939R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Part of the established ABB SACE Emax E4 series, it combines a rated current of 4000 A with the PR122/P-LI R4000 electronic overcurrent release.
The E4V performance level is intended for demanding power distribution installations with high prospective short-circuit currents. Its PR122/P-LI electronic release provides long-time overload and instantaneous short-circuit protection, helping protect switchboards, conductors and connected equipment against sustained overcurrents and severe short-circuit faults.
This configuration is the moving part of a four-pole withdrawable circuit breaker. It is fitted with four auxiliary contacts and open/closed position indication, while its withdrawable architecture enables the breaker moving part to be disconnected and removed from the compatible fixed part for inspection, maintenance or replacement.
