Why Choose the ABB E6V 5000 PR121/P-LSIG 5000A 3P Fixed Air Circuit Breaker?
The ABB E6V 5000 PR121/P-LSIG, order code 1SDA057106R1, 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 the PR121/P-LSIG R5000 electronic overcurrent release.
The E6V performance level is engineered for installations with very high prospective short-circuit currents. Its PR121/P-LSIG electronic release provides long-time, short-time, instantaneous and ground-fault protection, helping safeguard switchboards, conductors and connected equipment against overloads, short circuits and earth faults.
This configuration is a three-pole fixed circuit breaker equipped with rear horizontal terminals. It is also fitted with four auxiliary contacts and open/closed circuit-breaker position indication, providing useful status signalling for integration into high-current switchboards, power centres and critical electrical distribution systems.

Advanced Protection for High-Current Power Distribution
Air circuit breakers such as the ABB E6V 5000 provide primary switching and protection for large low-voltage electrical systems. With its 5000 A current rating and E6V high-performance construction, this SACE Emax breaker is suited to major incoming circuits and distribution systems where high continuous current capacity and dependable interruption of severe electrical faults are essential.
The PR121/P-LSIG electronic release provides comprehensive protection by responding to long-time overloads, short-time faults, instantaneous short circuits and ground faults. These LSIG functions support effective protection coordination and selectivity across complex distribution networks, while the fixed E6V construction and rear horizontal terminals provide a robust arrangement 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.
- Heavy manufacturing and large commercial facilities.
- High-current feeder and power distribution centre protection.
