Why Choose the ABB E4H/f 3200 PR122/P-LSI 3200A 4P Fixed Air Circuit Breaker?
The ABB 1SDA059433R1 is a high-performance SACE Emax E4H/f air circuit breaker designed for high-current low-voltage power distribution. Rated at 3200 A, this four-pole fixed configuration combines the E4H frame with a full-size neutral and the advanced PR122/P-LSI R3200 electronic overcurrent release.
The PR122/P-LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The addition of the short-time protection function supports selective coordination between upstream and downstream protective devices, helping maintain continuity of supply while providing dependable protection for busbars, cables, switchgear and connected equipment.
This model is the four-pole fixed version with rear horizontal terminals (F HR). Its full-size neutral configuration is suited to four-wire distribution systems requiring full neutral current capability, while the fixed construction provides a robust permanent installation for major industrial, commercial and infrastructure switchboards.

Selective LSI Protection for High-Current Distribution
The ABB SACE Emax E4H/f is engineered for major low-voltage distribution circuits where high continuous current, dependable fault interruption and effective protection coordination are essential. Its electronic overcurrent release monitors current conditions and initiates breaker operation when configured thresholds are exceeded, helping safeguard conductors, busbars, switchgear and connected loads.
The PR122/P-LSI release combines long-time overload protection with short-time and instantaneous short-circuit protection. The short-time function enables coordinated tripping strategies where downstream protective devices can clear suitable faults before the main breaker operates, while instantaneous protection provides rapid interruption of severe short-circuit conditions. Combined with its 3200 A rating and full-size-neutral four-pole construction, the 1SDA059433R1 is well suited to critical high-current distribution duties.
