Advanced LSIG Protection for Low-Voltage Power Distribution
The Ekip Aware LSIG release provides four principal protection functions for comprehensive circuit protection. Long-time protection addresses sustained overload conditions, short-time protection manages short-circuit events with controlled delay, instantaneous protection provides rapid response to high fault currents, and earth-fault protection detects current flowing through unintended paths to earth. With an Icu of 85 kA at 440 V and an Icw of 66 kA for 1 s, the E2.3S 800 configuration is suited to demanding low-voltage distribution applications.
Typical Applications
- Low-voltage main distribution boards
- Industrial electrical distribution systems
- Commercial power distribution installations
- Manufacturing and processing facilities
- Industrial switchboards
- Infrastructure power systems
- High-capacity electrical distribution assemblies
- Applications requiring comprehensive LSIG protection
