Reliable Electronic Circuit Protection for Industrial Power Distribution
Electronic moulded case circuit breakers such as the ABB EPX-2503-E2-MCCB protect electrical distribution systems against overloads and short-circuit faults. The electronic trip unit monitors current conditions and initiates circuit breaker operation when the configured protection thresholds are exceeded, helping protect electrical cables, connected equipment and distribution infrastructure from potentially damaging overcurrent conditions.
The ABB Tmax XT4 Ekip LSI protection system provides three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection introduces an adjustable delay for selected fault conditions, and instantaneous protection provides rapid tripping during severe short circuits. These characteristics support effective protection coordination and improved selectivity when the distribution system is correctly designed and configured.
Typical Applications
- Commercial building main and sub-distribution panelboards.
- Industrial low-voltage electrical distribution systems.
- ABB Protecta Power MCCB distribution assemblies.
- Manufacturing facilities and production equipment supply circuits.
- Electrical plant rooms and building services installations.
- Warehouses, logistics centres and commercial premises.
- Three-phase electrical distribution systems requiring 250 A circuit protection.
- Panel building and electrical infrastructure projects requiring adjustable electronic protection.
