Why Choose the ABB E4H3200 PR122/P-LSIG 3200A Air Circuit Breaker?
The ABB E4H3200 PR122/P-LSIG, order code 1SDA056829R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in demanding high-current low-voltage electrical distribution systems. Part of the ABB SACE Emax E4H series, this four-pole fixed circuit breaker combines a 3200 A rated uninterrupted current with the PR122/P-LSIG R3200 electronic overcurrent release.
The PR122/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, cables and connected equipment while supporting coordinated protection in major industrial and infrastructure distribution networks.
The 1SDA056829R1 is supplied as a four-pole fixed circuit breaker with rear horizontal terminals. The E4H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 400 V AC and 85 kA at 690 V AC, together with a rated short-time withstand current of 100 kA for 1 s, making it suitable for installations with substantial prospective fault currents.
