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.
K curve: close thermal protection with a high magnetic threshold, so motors, transformers and other inductive loads start without nuisance tripping.
