Why Choose the ABB 1SDA055812R1 E2B1600 Air Circuit Breaker Moving Part?
The ABB 1SDA055812R1 is a high-performance SACE Emax E2B1600 air circuit breaker (ACB) moving part designed for reliable switching and protection in demanding low-voltage electrical distribution systems. Part of the ABB New Emax series, this three-pole withdrawable breaker moving part combines a rated uninterrupted current of 1600 A with the advanced PR122/P-LSI R1600 electronic overcurrent release.
The PR122/P-LSI trip unit provides long-time (L), short-time (S) and instantaneous (I) protection. These electronically adjustable protection functions help safeguard conductors, switchgear and connected equipment against overload and short-circuit conditions while supporting coordinated protection throughout industrial and commercial distribution networks.
The 1SDA055812R1 is configured as the moving part of a three-pole withdrawable E2B1600 circuit breaker. It is fitted with four auxiliary contacts and open/closed position indication, while the withdrawable construction enables the breaker moving part to be isolated and removed from its compatible fixed part for inspection, maintenance or replacement.

Reliable Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E2B1600 provide switching, isolation and overcurrent protection for high-current low-voltage distribution circuits. The electronic protection release monitors current conditions and initiates circuit-breaker operation when configured overload, short-time or instantaneous short-circuit thresholds are exceeded.
The PR122/P-LSI release combines three complementary protection functions for coordinated electrical distribution. Its adjustable long-time, short-time and instantaneous characteristics enable protection settings to be matched to system requirements, while the withdrawable construction allows the breaker moving part to be removed from its compatible fixed portion for inspection, servicing and replacement.
Typical Applications
- Industrial low-voltage switchboards and distribution systems.
- Withdrawable power distribution assemblies.
- Main incoming circuit protection.
- High-current feeder protection.
- Manufacturing and process industry electrical systems.
- Commercial building power distribution.
- Infrastructure and utility electrical installations.
