Why Choose the ABB E6H 6300 PR122/P-LSI 6300A 3P Fixed Air Circuit Breaker?
The ABB E6H 6300 PR122/P-LSI, order code 1SDA057012R1, 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 6300 A with the PR122/P-LSI R6300 electronic overcurrent release.
The E6H performance level provides high short-circuit interruption capability for large industrial and infrastructure installations. Its PR122/P-LSI electronic release provides long-time, short-time and instantaneous overcurrent protection, helping protect switchboards, conductors and connected equipment against overloads and short circuits while supporting selective protection coordination.
This configuration is a three-pole fixed circuit breaker equipped with rear horizontal terminals. It is also fitted with four auxiliary contacts and circuit-breaker open/closed position indication, providing useful status signalling for integration into high-current switchboards and power distribution systems.

Advanced Protection for Very High-Current Power Distribution
Air circuit breakers such as the ABB E6H 6300 provide primary switching and protection for large low-voltage electrical systems. With its 6300 A rating and E6H high-performance construction, this SACE Emax breaker is suited to major incoming circuits and distribution systems where very high continuous current capacity and dependable interruption of severe fault currents are required.
The PR122/P-LSI electronic release provides long-time protection against sustained overloads, short-time protection for selective short-circuit coordination and instantaneous protection against severe faults. This combination supports effective protection coordination across complex electrical networks, while the fixed E6H construction and rear horizontal terminals provide a robust arrangement for permanently installed high-current switchgear.
Typical Applications
- Main incoming protection in very 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.
- Heavy manufacturing and large commercial facilities.
- High-current feeder and power distribution centre protection.
