Why Choose the ABB E6V 5000 PR121/P-LSI 5000A 3P Fixed Air Circuit Breaker?
The ABB E6V 5000 PR121/P-LSI, order code 1SDA057105R1, 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 uninterrupted current of 5000 A with the PR121/P-LSI R5000 electronic overcurrent release.
The E6V performance level is engineered for installations with very high prospective short-circuit currents, providing a rated ultimate short-circuit breaking capacity of 150 kA at 400 V AC. Its PR121/P-LSI electronic release provides long-time, short-time and instantaneous protection, helping protect conductors, switchboards and connected equipment against overloads and short circuits.
This configuration is a three-pole fixed circuit breaker equipped with rear horizontal terminals. Four auxiliary change-over contacts and open/closed circuit-breaker position indication support status monitoring and integration into high-current switchboards, power centres and critical distribution systems.

High-Performance Protection for Critical Power Distribution
Air circuit breakers such as the ABB E6V 5000 provide primary switching and protection for major low-voltage electrical systems. With a rated uninterrupted current of 5000 A and an ultimate short-circuit breaking capacity of 150 kA at 400 V AC, this SACE Emax breaker is particularly suited to networks where both high continuous current capacity and exceptional fault interruption capability are required.
The PR121/P-LSI electronic release provides long-time protection against sustained overloads, short-time delayed protection for selective fault coordination and instantaneous protection against severe short circuits. Adjustable protection settings allow the breaker to be coordinated with the characteristics of the electrical installation, while the fixed construction and rear horizontal terminals provide a robust arrangement for permanent switchgear installations.
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.
