Why Choose the ABB E6H-A 5000 PR121/P-LSIG Air Circuit Breaker?
The ABB E6H-A 5000 PR121/P-LSIG, order code 1SDA058047R1, is a heavy-duty three-pole air circuit breaker (ACB) from the ABB SACE Emax range, designed for protection and switching in high-current low-voltage electrical distribution systems. With a rated current of 5000 A, the E6H-A is suited to major incoming supplies, high-capacity feeders and other demanding power-distribution applications.
The integrated PR121/P-LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This combination provides comprehensive electronic protection for conductors, switchgear and connected equipment while supporting coordinated protection throughout the electrical installation.
Built around the large E6 frame, the E6H-A 5000 is engineered for installations requiring very high continuous-current capacity and dependable fault interruption. Its robust SACE Emax construction and electronic protection make it suitable for industrial plants, infrastructure, commercial facilities and other critical low-voltage distribution systems.

Reliable Protection for High-Current Distribution Systems
Air circuit breakers such as the ABB E6H-A provide switching and protection for main incoming supplies, busbars and high-current distribution feeders. The electronic trip unit monitors current conditions and initiates breaker operation when configured overload, short-circuit or ground-fault thresholds are exceeded.
The PR121/P-LSIG release combines four principal protection functions in one electronic trip unit, making the E6H-A 5000 suitable for coordinated low-voltage distribution networks. Its high current rating makes it particularly appropriate for large switchboards serving substantial industrial and infrastructure loads.
Typical Applications
- Main incoming protection in high-capacity low-voltage switchboards.
- Industrial power distribution systems.
- High-current feeder and busbar protection.
- Manufacturing and process plant electrical systems.
- Commercial and infrastructure power distribution.
- Large low-voltage switchgear and distribution assemblies.
