Advanced LSIG Protection for Low-Voltage Power Distribution
The ABB E2.3S 2000 uses an Ekip Aware LSIG electronic release to provide adjustable protection against the principal overcurrent conditions encountered in low-voltage distribution systems. Long-time protection helps manage sustained overloads, short-time protection supports selective coordination, instantaneous protection responds rapidly to severe short-circuit conditions, and earth-fault protection helps detect faults involving the earth. With an 85 kA Icu and 66 kA Icw at 440 V, the 1SDA128832R1 is designed for demanding power distribution applications where high fault interruption and short-time withstand capability are required.
Typical Applications
- Main incomer and feeder protection in low-voltage switchboards.
- Industrial power distribution systems requiring 2000 A continuous current capacity.
- Commercial and infrastructure electrical distribution assemblies.
- Protection of high-capacity feeders and distribution circuits.
- Switchboard installations requiring fixed 3-pole air circuit breakers with rear horizontal terminals.
- Electrical systems requiring adjustable LSIG protection and high short-circuit performance.
