Why Choose the ABB E6V 5000 PR121/P-LSIG 5000A 3P Withdrawable Air Circuit Breaker?
The ABB E6V 5000 PR121/P-LSIG, order code 1SDA057122R1, is a high-capacity three-pole withdrawable air circuit breaker moving part designed for demanding low-voltage power distribution systems. Part of the ABB SACE Emax E6 series, it combines a rated uninterrupted current of 5000 A with the PR121/P-LSIG R5000 electronic overcurrent release.
The E6V performance level is designed for installations with very high prospective fault currents, with a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC, 50 Hz. Its PR121/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection, delivering comprehensive protection against overloads, short circuits and earth faults.
This configuration is the moving part of a three-pole withdrawable circuit breaker and is intended for use with the corresponding compatible SACE Emax fixed part. The breaker is rated for 690 V AC systems and incorporates four auxiliary contacts arranged as two normally open and two normally closed contacts, together with open/closed position indication.
Key Advantages
- Very high 5000 A rated uninterrupted current for major low-voltage distribution systems.
- Three-pole withdrawable configuration for maintainable high-current installations.
- PR121/P-LSIG R5000 electronic overcurrent release.

Comprehensive Protection for High-Current Power Distribution
Air circuit breakers such as the ABB E6V 5000 provide primary switching and protection for major low-voltage electrical systems. With its 5000 A continuous current capability, 690 V AC rating and 150 kA ultimate breaking capacity at 400 V AC, this SACE Emax moving part is suited to distribution networks where substantial load currents and high prospective fault levels must be safely managed.
The PR121/P-LSIG electronic release provides long-time protection against sustained overloads, short-time protection for coordinated fault clearing, instantaneous protection against severe short circuits and integrated ground-fault protection. Combined with the withdrawable Emax architecture, these functions support protection coordination while allowing the breaker moving part to be isolated and removed from its compatible fixed part for inspection, servicing or replacement.
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.
- Heavy manufacturing and large commercial facilities.
- High-current feeders and power distribution centres.
