Advanced LSIG Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax 2 E1.2C protect high-current electrical distribution circuits against potentially damaging electrical faults while also providing dependable switching and isolation. The E1.2C performance level combines a compact frame with substantial short-circuit capability, making it particularly suitable for main distribution boards, industrial switchgear and other installations with high prospective fault currents.
The Ekip Hi-Touch LSIG trip unit provides comprehensive electronic protection through long-time, short-time, instantaneous and ground-fault functions. The additional ground-fault protection distinguishes the LSIG configuration from LSI variants and provides an enhanced level of protection for electrical distribution systems where earth and ground faults must be detected and cleared reliably.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical infrastructure.
- Transformer secondary protection.
- Manufacturing and process plant switchgear.
- Power distribution panels and switchgear assemblies.
- High-current feeder and incomer protection.
- Automation and energy-management systems.
