Why Choose the ABB 1SDA055813R1 E2B1600 Air Circuit Breaker Moving Part?
The ABB 1SDA055813R1 is a high-performance SACE Emax E2B1600 air circuit breaker (ACB) moving part designed for dependable 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 PR122/P-LSIG R1600 electronic overcurrent release.
The PR122/P-LSIG trip unit provides comprehensive long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection. These electronically adjustable protection functions help safeguard conductors, switchgear and connected equipment against overloads, short circuits and earth faults while supporting coordinated protection throughout industrial and commercial distribution networks.
The 1SDA055813R1 is configured as the moving part of a three-pole withdrawable E2B1600 circuit breaker. It has a rated uninterrupted current of 1600 A, a rated voltage of 690 V AC and a rated ultimate short-circuit breaking capacity of 42 kA at 400 V AC, 50 Hz, with auxiliary contacts and open/closed position indication for integration into switchboard monitoring and control systems.

Comprehensive Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E2B1600 provide switching, isolation and protection for high-current low-voltage distribution circuits. The electronic protection release monitors current conditions and initiates circuit-breaker operation when configured overload, short-circuit or earth-fault thresholds are exceeded.
The PR122/P-LSIG release combines four complementary protection functions for sophisticated electrical distribution applications. Adjustable long-time, short-time, instantaneous and earth-fault protection supports effective system coordination, while the withdrawable construction allows the breaker moving part to be removed from its compatible fixed portion for inspection, maintenance 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.
