Advanced LSIG Protection and Power Monitoring
Air circuit breakers protect low-voltage distribution systems by interrupting abnormal currents before cables, busbars and connected equipment are exposed to unacceptable thermal or electrodynamic stress. The ABB E2.2S 250 combines high short-circuit performance with an advanced electronic protection platform, delivering an 85 kA breaking capacity at 440 V AC and comprehensive LSIG protection for demanding distribution networks.
The Ekip Hi-Touch LSIG trip unit provides adjustable long-time overload, short-time selective, instantaneous short-circuit and earth-fault protection. Its integrated Ekip Measuring Pro and Network Analyzer functions extend the breaker beyond circuit protection by providing detailed electrical measurements and power-quality information for monitoring and management of modern electrical installations.
Typical Applications
- Main and sub-main low-voltage power distribution switchboards.
- Industrial manufacturing and process facilities.
- Commercial buildings and critical infrastructure.
- Data centres and high-availability electrical distribution systems.
- Feeder protection requiring advanced LSIG functionality.
- Installations requiring integrated electrical measurement and power-quality analysis.
