Advanced LSIG Protection for Low-Voltage Power Distribution
The Ekip Aware LSIG release combines four fundamental protection functions in one electronic trip unit. Long-time protection helps protect conductors and equipment against sustained overloads, while short-time and instantaneous protection provide rapid response to high-current fault conditions. Earth-fault protection adds dedicated protection against ground-fault currents. This makes the ABB 1SDA128830R1 suitable for applications where coordinated and comprehensive circuit protection is required.
Typical Applications
- Low-voltage main distribution boards
- Industrial electrical distribution systems
- Commercial building power distribution
- Manufacturing plants and production facilities
- Power distribution assemblies and switchboards
- Large electrical loads requiring 2000 A switching and protection
- Infrastructure and energy distribution installations
