Bussmann CH 3-Pole Modular Fuse Holder, DIN Rail Mount

The Bussmann CH 3-Pole Modular Fuse Holder is part of Eaton's Bussmann series of DIN rail-mounted fuse holders, rated 690V a.c./750V d.c. (IEC) and 700V a.c. (UL), and offered in amperage ratings from 143A to 224A depending on the option selected. Fitted with a neon indicator and sized for 14 x 51 mm cylindrical fuses, this modular holder is built for dependable overcurrent protection in three-phase circuits. With an IP20 degree of protection, lockable construction, and CE marking, it is engineered for professional panel-building and industrial control applications.

Bussmann CH221DU – Frequently Asked Questions

1) Will a Bussmann CH fuse holder mount in my existing control panel?
It mounts on standard DIN rail, so if your panel already has rail runs for breakers and terminal blocks the CH holder clips straight on beside them. No panel drilling, no separate mounting plate. It is a 3-pole modular body, so one unit covers all three phases rather than ganging three single-pole holders.
2) Can I use this Bussmann holder to switch a neutral along with the three phases?
No. The CH 3-pole holder does not switch a neutral concurrently, so it protects the three phase conductors only. If your design calls for the neutral to be broken at the same time as the phases, you need a 3P+N holder instead of this one.
3) Which Bussmann CH part number do I order for my amp rating?
Six ratings are offered, each with its own part number: 143A is CH143DIU, 144A is CH144DIU, 221A is CH221DU, 222A is CH222DIU, 223A is CH223DU and 224A is CH224DU. Order by the part number, not the amp figure alone, since adjacent ratings sit only one amp apart.
4) What voltage is the Bussmann CH 3-pole fuse holder rated for?
690V a.c. / 750V d.c. under IEC and 700V a.c. under UL. That covers 480V and 600V three-phase distribution as well as d.c. bus work up to 750V, which is why it turns up in machine-building and automation panels rather than just general lighting boards.
5) How do I tell if a fuse has blown without pulling it out of the holder?
The CH holder carries a built-in neon indicator that lights to flag a blown link, so a tech can spot the failed pole on a walk-by instead of opening carriers one at a time. Useful on panels where downtime diagnosis matters more than the cost of the holder.
6) Is the Bussmann CH fuse holder safe to leave exposed inside an enclosure with live terminals nearby?
The housing is IP20, which means finger-safe against accidental contact and small debris but not sealed against dust or water. It belongs inside an enclosure, not on an open wall or in a washdown area. If a technician needs to be kept out of the fuse entirely, the holder is also lockable.
7) Does the Bussmann CH fuse holder meet IEC standards for a European-spec machine build?
It is built to IEC 60269-2 and is CE Marked, which is what an OEM exporting a control panel into Europe needs on the fuse holder line of the bill of materials. The dual IEC and UL voltage ratings also let the same panel design carry over to North American jobs.
8) Does buying the Bussmann CH holder include the fuses?
No. The CH is the holder only, a fuse accessory. You order the 14 x 51 mm cylindrical fuse links separately and size them to the circuit you are protecting.
