Why Choose the ABB E3H-A 2000 PR123/P-LSIG Air Circuit Breaker?
The ABB E3H-A 2000 PR123/P-LSIG, order code 1SDA057653R1, is a high-performance SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage electrical distribution systems. This UL three-pole withdrawable configuration combines the E3H-A breaker platform with an advanced PR123/P-LSIG R2000 electronic overcurrent release.
With a rated current of 2000 A, the breaker provides comprehensive LSIG protection comprising long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault functions. The PR123/P electronic release supports accurate and coordinated protection for high-current industrial and commercial distribution networks.
The 1SDA057653R1 is the withdrawable moving part of the breaker and is intended for use with the corresponding SACE Emax fixed part. It is fitted with four auxiliary contacts and open/closed position indication, providing useful status signalling for switchboard control and monitoring systems.

Advanced Protection for High-Current Distribution
Air circuit breakers such as the ABB SACE Emax E3H-A provide switching and fault protection for high-current low-voltage distribution circuits. Electronic trip technology monitors electrical conditions and initiates circuit interruption when configured protection thresholds are exceeded.
The PR123/P-LSIG release combines overload, selective short-circuit, instantaneous short-circuit and ground-fault protection. Together with the withdrawable Emax construction, this provides comprehensive electrical protection while allowing the breaker moving part to be isolated and removed for servicing or replacement.
Typical Applications
- Industrial low-voltage switchboards.
- Main incoming electrical distribution circuits.
- High-current distribution feeders.
- Manufacturing and process plants.
- Commercial and infrastructure power systems.
- Transformer and generator distribution systems.
