Quick-connect terminal version with final T suffix. The current catalogue technical summary gives a 1–63A family range, but the published ordering table explicitly lists 10–63A codes; only those exact tabulated codes are selectable here. AC120/240V is a slash voltage rating, so match the actual system earthing and pole application.
Typical applications
- Branch-circuit overcurrent protection in panels designed for the B1NQ quick-connect terminal system.
- OEM electrical assemblies requiring a documented UL 489 pole/current/curve combination.
