Description

The ABB S800U is a high-performance UL 489 circuit breaker for currents up to 100 A, with 30 kA (1-pole) / 50 kA (multi-pole) interrupting rating at 240 VAC, ring-tongue compatible terminals and a full range of shunt trips, undervoltage releases, auxiliary contacts and handles.

Z curve: very low magnetic threshold (roughly 2–3 × In), for sensitive electronics, semiconductors and measuring/voltage-transformer circuits.
