Why Choose the ABB E6H5000 PR121/P-LSIG 5000A 3-Pole Withdrawable Air Circuit Breaker?
The ABB 1SDA056994R1 is a high-performance SACE Emax E6H air circuit breaker moving part designed for protection and switching of high-current low-voltage electrical distribution systems. As part of the ABB New Emax series, the E6H5000 combines a substantial 5000 A current rating with the electronic PR121/P-LSIG overcurrent release for comprehensive protection in demanding industrial and infrastructure power distribution applications.
This three-pole withdrawable circuit breaker moving part is equipped with the PR121/P-LSIG electronic trip unit, providing long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. Its withdrawable configuration allows the moving part to be isolated and removed from the associated fixed part, supporting maintenance, inspection and replacement within compatible switchgear.
With a rated operational current of 5000 A, rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 100 kA throughout its specified 220–690 V AC range, the E6H5000 is engineered for high-capacity distribution systems where robust fault protection, selective coordination and serviceability are essential.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E6H5000 provide switching and protection for high-current low-voltage distribution circuits. The electronic trip unit monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded, helping protect busbars, cables, transformers and connected equipment against damaging overload, short-circuit and earth-fault conditions.
The PR121/P-LSIG release combines long-time, selective short-circuit, instantaneous and earth-fault protection functions, allowing the breaker to support coordinated protection strategies in complex electrical distribution networks. The withdrawable moving-part configuration also facilitates isolation, maintenance and replacement within compatible switchgear, making the 1SDA056994R1 particularly suitable for critical high-capacity installations where serviceability and comprehensive fault protection are required.
Typical Applications
- Low-voltage main distribution switchboards.
- Withdrawable industrial switchgear assemblies.
- High-current incoming and feeder circuits.
- Manufacturing and process plants.
- Commercial and infrastructure power distribution.
- Transformer secondary protection and switching.
- Generator and utility distribution systems.
- High-capacity electrical distribution installations requiring earth-fault protection.
