The Fuji Electric BZ6V10D is a door-mounted handle operation mechanism for Fuji BW/BZ-series molded-case circuit breakers — it lets you open the enclosure door and still switch the breaker, with the door closed. The kit is the full set: black square escutcheon plate, rotating handle with a padlock hasp (Padlock PA), drive mechanism, four mounting screws and two extension studs for the door thickness. Two kits arrived new in factory cartons on 2026-01-23, each with its multilingual manual, 1-year warranty, made in Japan at Fuji's Otawara plant.

Installation notes

The mechanism bolts through the enclosure door; the two supplied studs span the door thickness between the handle and the breaker body, so order the door cutout depth against your cabinet. The Padlock PA hasp takes a padlock shank to hold the handle in OFF — that is the door-closed lockout path for LOTO. The green OPEN/RESET sector re-latches a tripped breaker without opening the door.
