Why Choose the ABB E3V3200 PR121/P-LSI Air Circuit Breaker?
The ABB E3V3200 PR121/P-LSI, order code 1SDA056697R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection in high-current low-voltage power-distribution systems. Part of the ABB SACE Emax E3 series, this four-pole fixed circuit breaker combines a 3200 A rated current with the PR121/P-LSI R3200 electronic overcurrent release.
The PR121/P-LSI release provides long-time, short-time and instantaneous overcurrent protection, helping protect switchboards, conductors and downstream equipment against overloads and short circuits. Its adjustable protection functions support coordinated protection schemes and selective fault clearing in demanding industrial and commercial electrical distribution networks.
This configuration is a four-pole fixed circuit breaker with rear horizontal terminals. It is rated for operation up to 690 V AC and provides a rated ultimate short-circuit breaking capacity of 130 kA at 400 V AC, making it suitable for substantial low-voltage switchboards where high current capacity and robust fault protection are required.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E3V3200 provide switching and overcurrent protection at main incomer and feeder levels within low-voltage distribution systems. The PR121/P-LSI electronic release monitors circuit current and provides long-time protection against sustained overloads, short-time protection for coordinated fault clearing and instantaneous intervention against severe short-circuit currents.
The combination of a 3200 A current rating, four-pole construction and high E3V breaking performance makes the 1SDA056697R1 particularly suitable for substantial industrial and commercial switchboards. Its fixed construction and rear horizontal terminals support permanent busbar integration, while adjustable LSI protection enables coordination with upstream and downstream protective devices.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power-distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer secondary and main incomer protection.
- High-current feeder protection.
- Power distribution and control assemblies.
