Why Choose the ABB E3H3200 PR121/P-LSIG 3200A 4P Fixed Air Circuit Breaker?
The ABB E3H3200 PR121/P-LSIG, order code 1SDA056506R1, is a high-performance 3200 A four-pole fixed air circuit breaker from the ABB SACE Emax E3 series, engineered for switching and protection in demanding low-voltage power distribution systems. This E3H configuration combines high-current switching capability with the PR121/P-LSIG R3200 electronic overcurrent release.
The PR121/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 LSIG protection functions make the breaker suitable for coordinated distribution systems requiring comprehensive electronic fault protection.
With a rated uninterrupted current of 3200 A, a four-pole configuration and operation up to 690 V AC, the E3H3200 is suited to substantial three-phase distribution systems requiring neutral switching. The fixed breaker uses rear horizontal terminals and provides an ultimate short-circuit breaking capacity of 100 kA at 220–500 V AC.
