Why Choose the ABB E6H 6300 PR123/P-LSIG 6300A 3P Withdrawable Air Circuit Breaker?
The ABB 1SDA057031R1 is a high-performance SACE Emax E6H air circuit breaker moving part designed for protection and switching in high-current low-voltage electrical distribution systems. Rated at 6300 A, this three-pole withdrawable breaker incorporates an ABB PR123/P-LSIG R6300 electronic overcurrent release providing long-time, short-time, instantaneous and earth-fault protection.
As part of the proven ABB SACE Emax series, the E6H 6300 is engineered for demanding industrial, infrastructure and commercial power distribution applications. Its withdrawable moving-part construction allows the breaker to be isolated and removed from the associated fixed part, supporting efficient inspection, servicing and replacement in critical high-current switchboards.
The advanced PR123/P-LSIG electronic trip unit combines comprehensive LSIG protection with the high-current capability of the E6H frame. The breaker moving part is also fitted with four auxiliary contacts and open/closed position indication, supporting integration with switchboard signalling, monitoring and control systems.

Reliable Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E6H provide switching and overcurrent protection for major low-voltage distribution circuits. The electronic trip unit monitors electrical conditions and initiates circuit-breaker operation when configured overload, short-circuit or earth-fault thresholds are exceeded, helping protect busbars, cables, transformers and connected electrical equipment.
The PR123/P-LSIG release combines long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection in an advanced electronic trip unit. Together with the E6H frame's 6300 A current capability and withdrawable construction, it provides comprehensive protection and maintainability for critical high-current distribution networks.
Typical Applications
- Main incoming circuit breakers in high-current low-voltage switchboards.
- Industrial power distribution systems.
- High-current feeder protection.
- Transformer secondary protection and switching.
- Generator protection and distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure power distribution.
- Switchboards requiring withdrawable high-current circuit breakers with comprehensive LSIG protection.
