Why Choose the ABB E1N800 PR122/P-LSIG 800A 3P Withdrawable Air Circuit Breaker?
The ABB E1N800 PR122/P-LSIG, order code 1SDA055717R1, is a high-performance SACE Emax air circuit breaker moving part designed for switching and comprehensive protection in low-voltage power distribution systems. Rated at 800 A, this three-pole unit combines the E1N frame with the PR122/P-LSIG R800 electronic overcurrent release.
This model is supplied as a withdrawable moving part (W MP) for installation with the corresponding SACE Emax fixed part. The withdrawable design enables the breaker to be isolated and removed for inspection, maintenance or replacement, making it particularly suitable for industrial switchboards where serviceability and continuity of operation are important.
The PR122/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. With a rated operational voltage of 690 V AC and an ultimate short-circuit breaking capacity of 50 kA at 400–415 V AC, the E1N800 provides comprehensive protection for demanding power distribution applications.

Comprehensive Protection for Low-Voltage Power Distribution
The ABB SACE Emax E1N800 is engineered for switching, isolation and protection of high-current low-voltage distribution circuits. Its withdrawable construction enables the moving portion to be separated from the corresponding fixed part, supporting efficient maintenance, testing and replacement in critical switchboard installations.
The PR122/P-LSIG electronic release provides coordinated protection against overloads, delayed and instantaneous short circuits and ground faults. Combined with the E1N platform's 50 kA breaking capability, the 1SDA055717R1 provides a robust solution for main incomers, feeders and other critical distribution circuits requiring comprehensive LSIG protection.
Typical Applications
- Industrial low-voltage switchboards.
- Main incoming circuit protection.
- High-current feeder protection.
- Manufacturing and process plants.
- Commercial building power distribution.
- Infrastructure power distribution systems.
- Withdrawable switchgear requiring comprehensive LSIG protection.
