Advanced Protection for High-Current 900 V Power Distribution
Air circuit breakers such as the ABB Emax 2 E4.2H/E9 are designed to protect high-current electrical distribution systems against damaging overloads, short circuits and earth faults. The Ekip Hi-Touch electronic trip unit continuously supports protection functions based on configured operating thresholds, allowing the breaker to disconnect a circuit when abnormal electrical conditions require protective intervention.
The LSIG functionality combines long-time protection against sustained overloads, short-time protection for selective fault coordination, instantaneous protection against severe short circuits and ground-fault protection for earth-fault conditions. Together with a 3200 A current rating, 75 kA Icu and Ics at 900 V AC and withdrawable Emax 2 architecture, the 1SDA104520R1 provides a powerful protection solution for critical high-energy switchboards.
Typical Applications
- High-current industrial 900 V AC distribution systems.
- Main incomer and distribution circuit protection.
