Comprehensive Withdrawable Protection for Low-Voltage Distribution
Withdrawable air circuit breakers provide high-current switching and protection while allowing the circuit-breaker moving assembly to be separated from its compatible fixed part for inspection, servicing or replacement. This architecture is particularly valuable in industrial switchboards where maintainability, equipment availability and efficient servicing are important design requirements.
The ABB PR123/P-LSIG electronic release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Combined with the E1B 800 frame, four-pole configuration, 42 kA short-circuit performance and withdrawable moving-part construction, the 1SDA055631R1 provides comprehensive protection for compatible ABB SACE Emax low-voltage power distribution assemblies.
Typical Applications
- Low-voltage industrial power distribution systems.
- Withdrawable main and distribution switchboards.
- Four-pole electrical distribution systems.
- Transformer and generator protection systems.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure power distribution installations.
- Critical power distribution systems requiring LSIG protection.
