Why Choose the ABB E6H 5000 PR122/P-LSIG 5000A 3P Fixed Air Circuit Breaker?
The ABB E6H 5000 PR122/P-LSIG, order code 1SDA056981R1, is a high-capacity three-pole fixed air circuit breaker (ACB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Emax E6 series, it combines a rated current of 5000 A with a PR122/P-LSIG R5000 electronic overcurrent release.
The E6H performance level is designed for high-current installations requiring substantial short-circuit interruption capability. Its PR122/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection functions, helping safeguard switchboards, conductors and connected equipment against overloads, short circuits and earth faults while supporting coordinated protection schemes.
This configuration is a three-pole fixed circuit breaker with rear horizontal terminals. It is supplied with four auxiliary contacts for open/closed circuit-breaker status indication, making it a robust solution for major incoming supplies, transformer secondary systems, industrial power centres and other critical high-current distribution applications.

Advanced Protection for High-Current Power Distribution
Air circuit breakers such as the ABB E6H 5000 provide primary switching and protection for large low-voltage electrical systems. With its 5000 A current rating and E6H high-performance construction, this SACE Emax breaker is particularly suited to major incoming circuits and distribution systems where high continuous current capacity and dependable fault interruption are essential.
The PR122/P-LSIG electronic release provides comprehensive LSIG protection by responding to long-time overloads, short-time faults, severe instantaneous short circuits and ground faults. These functions support coordinated fault protection across complex distribution networks while the fixed E6H construction provides a robust solution for permanently installed high-current switchgear.
Typical Applications
- Main incoming protection in high-capacity low-voltage switchboards.
- Industrial power distribution and heavy process plants.
- Transformer secondary and distribution protection.
- Generator and utility distribution systems.
- Large data centres and critical infrastructure power systems.
- Large manufacturing and commercial facilities.
- High-current feeder and power distribution centre protection.
