Why Choose the ABB E6H/f 6300 PR122/P-LSIG 6300A 4-Pole Withdrawable Circuit Breaker?
The ABB E6H/f 6300 PR122/P-LSIG, order code 1SDA055597R1, is the moving part of a high-capacity SACE Emax withdrawable air circuit breaker designed for protection and switching in demanding low-voltage power distribution systems. Rated at 6300 A, this four-pole unit combines the E6H high-breaking-capacity frame with a PR122/P-LSIG electronic overcurrent release for comprehensive circuit protection.
The PR122/P-LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection, enabling the breaker to protect against overloads, short circuits and earth faults. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 100 kA at 400 V AC, the E6H/f 6300 is suited to high-fault-level industrial and infrastructure distribution systems.
This configuration is a four-pole withdrawable moving part with a full-size neutral and is intended for use with the corresponding SACE Emax fixed part. It is equipped with four change-over auxiliary contacts and circuit-breaker open/closed position indication, providing useful status information for switchboard monitoring and control systems.

Comprehensive Withdrawable Protection for High-Current Distribution
Air circuit breakers such as the ABB E6H/f 6300 provide switching and overcurrent protection for high-current low-voltage distribution networks. The PR122/P-LSIG electronic release monitors electrical conditions and initiates circuit-breaker operation when configured protection thresholds are exceeded, helping safeguard cables, busbars, switchgear and connected equipment against overloads, short circuits and earth faults.
The withdrawable moving-part configuration is particularly valuable in critical switchboards where maintenance accessibility and reduced service interruption are important. Combined with the 6300 A E6H/f frame, full-size neutral and comprehensive LSIG protection, this unit is well suited to main distribution positions in large industrial, infrastructure and commercial power systems.
Typical Applications
- Main incomers for high-current low-voltage switchboards.
- Withdrawable power distribution assemblies.
- Industrial manufacturing and process facilities.
- Large commercial and infrastructure electrical systems.
- Power generation and utility distribution installations.
- Transformer secondary and main distribution protection.
- Critical power systems requiring selective and earth-fault protection.
