Panel builders using a 60 mm busbar system can mount Class J fusing straight onto the bars instead of wiring separate fuse blocks. Item 33310 is a Wöhner QUADRON 60Classic busbar-mounted fuse holder for Class J cylindrical fuses, 3-pole, rated 200 A and 600 V AC/DC for 41 x 146 fuses. It connects top or bottom and clips onto 12, 20 or 30 x 10 mm busbars.
Why panel builders pick it

- Class J fusing up to 200 A at 600 V AC or DC.
- Top or bottom cable connection to suit the panel layout.
- 150 mm² terminals for large load conductors.

Pro tip from the counter
Wöhner states these terminals are not suitable for aluminum cable. If the load conductors on this feeder are aluminum, plan a copper transition or pick a holder rated for aluminum before the panel is built, since swapping terminations after inspection is costly.
Best for: industrial control panels on 60 mm busbar systems, Class J feeder protection, OEM machine panels, replacing existing 60Classic fuse holders
