Why Choose the ABB 1SDA055825R1 E2B2000 Air Circuit Breaker?
The ABB 1SDA055825R1 is a high-performance SACE Emax E2B2000 air circuit breaker (ACB) designed for dependable switching and protection in high-current low-voltage electrical distribution systems. Part of the ABB New Emax series, this three-pole fixed circuit breaker combines a rated uninterrupted current of 2000 A with the PR121/P-LSI R2000 electronic overcurrent release.
The PR121/P-LSI trip unit provides long-time (L), short-time (S) and instantaneous (I) protection. These electronic protection functions help safeguard conductors, switchgear and connected equipment against overload and short-circuit conditions while supporting coordinated protection throughout industrial, commercial and infrastructure distribution networks.
This E2B2000 configuration features a three-pole fixed construction for permanent integration into compatible low-voltage switchgear. Combining a 2000 A current rating with adjustable LSI protection, the 1SDA055825R1 is well suited to main incoming and high-current feeder applications where reliable circuit protection and selective coordination are required.

Advanced Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E2B2000 provide switching, isolation and overcurrent protection for high-current low-voltage distribution circuits. The electronic trip unit monitors current conditions and initiates circuit-breaker operation when configured long-time overload, short-time or instantaneous short-circuit thresholds are exceeded.
The PR121/P-LSI release combines three complementary protection functions to support effective coordination within complex electrical networks. Short-time protection can provide greater selectivity between upstream and downstream protective devices, while the fixed E2B2000 construction makes the 1SDA055825R1 suitable for permanent integration into industrial switchboards and main distribution assemblies.
Typical Applications
- Industrial low-voltage switchboards and distribution panels.
- Main incoming circuit protection.
- High-current feeder circuit protection.
- Commercial building electrical distribution systems.
- Manufacturing and process industry power systems.
- Infrastructure and utility distribution equipment.
- High-current plant and machinery electrical installations.
