Bussmann CH223DMSU-F – Frequently Asked Questions

1) How does the CH223DMSU-F mount in a panel, and how much rail space does it need?
It is a DIN rail mounted modular holder that occupies 6 modular spacings on the rail. Plan the enclosure around a body of 107 x 123 x 102 mm and about 570 g of weight on the rail.
2) What are the voltage and current ratings on the Bussmann CH223DMSU-F three-pole fuse holder?
Rated 690 V a.c. / 1000 V d.c. and 125 A under IEC, and 700 V a.c. / 100 A under UL. The lower UL figures are the ones to design to on a North American job, so treat it as a 100 A device there.
3) What does the microswitch on the CH223DMSU-F do and why would I specify it?
The -F suffix version is fitted with an auxiliary microswitch that signals the holder's position, so a PLC or control circuit can be told when the fuse carrier has been pulled open. That is how you get remote indication of an isolated circuit. Note the holder has no optical defect indication, so the microswitch is the signalling you get, not a blown-fuse LED.
4) Is the CH223DMSU-F a fuse, or do I order the fuse links separately?
It is the holder only, a fuse accessory. The 22 x 58 mm cylindrical links, Eaton C22M or C22G, are a separate order, and you need three of them for the three poles.
5) Can I lock out the CH223DMSU-F fuse holder for maintenance?
Yes. The holder is lockable, so the carrier can be secured in the open position for a lockout/tagout on the circuit. Combined with the microswitch, you get both a physical lock and a remote signal that the disconnect is open.
6) Does this three-pole Bussmann holder switch the neutral as well?
No. The CH223DMSU-F is a straight three-pole device with no concurrently switching neutral pole. If your installation needs the neutral broken at the same time, you need a 3P+N version instead.
7) Is the Bussmann CH223DMSU-F safe to touch with the cover open, and can it go in an open enclosure?
It carries IP20 protection, which is finger-safe against solid objects 12 mm and larger but offers no protection against water. It belongs inside an enclosure, not exposed outdoors or in a washdown area.
8) What standard does this Bussmann modular fuse holder meet for a European spec job?
It is built to IEC 60269-2 and is CE Marked, which is what a specifier on a European or IEC-referenced drawing will be looking for on a low-voltage fuse holder of this class.
