Why Choose the ABB E3H2000 PR122/P-LSIG 2000A 3P Withdrawable Air Circuit Breaker?
The ABB E3H2000 PR122/P-LSIG, order code 1SDA056453R1, is a high-performance 2000 A three-pole air circuit breaker moving part from the ABB SACE Emax E3 series, engineered for switching and protection in demanding low-voltage industrial and commercial power distribution systems. This E3H configuration combines withdrawable switchgear flexibility with the PR122/P-LSIG R2000 electronic overcurrent release.
The PR122/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection, helping protect cables, busbars, transformers and connected equipment against overloads, short circuits and earth faults. Its electronic protection platform is suitable for coordinated distribution systems requiring adjustable protection and reliable fault discrimination.
With a rated current of 2000 A, a three-pole configuration and a rated operational voltage of 690 V AC, the E3H2000 is designed for substantial distribution loads. Its H-performance design delivers an ultimate short-circuit breaking capacity of up to 100 kA, while the withdrawable moving-part construction facilitates inspection, servicing and replacement within compatible SACE Emax switchgear.
