Bussmann CHM1DCU – Frequently Asked Questions

1) Can the Bussmann CHM fuse holder be used on a DC circuit, like a solar or battery system?
Yes. The CHM modular fuse holder is rated 600 Vac and 1000 Vdc, so it covers both AC panel work and higher-voltage DC circuits up to 1000 V. That DC rating is what separates it from AC-only holders in a PV combiner or battery distribution cabinet.
2) Is the CHM fuse holder single-pole or multi-pole, and how do I protect a three-phase circuit with it?
Each CHM is a single-pole holder. For a three-phase feeder you order three of them, one per phase, and gang them side by side in the panel. That single-pole modular format is also what lets you fuse only the legs you need on a control circuit rather than buying a fixed multi-pole block.
3) Will the CHM holder hold up on a service with high available fault current?
It carries a 200 kA short-circuit rating, which covers the interrupting duty on essentially any commercial or industrial service where the available fault current has been calculated. Confirm the fuse you install is rated for the same interrupting level, since the holder rating alone doesn't set the circuit's interrupting capacity.
4) Is the Bussmann CHM approved for use in UL-listed panels and export equipment?
The CHM is UL Listed and built to IEC requirements, so it can go into UL-labelled panels for the North American market and into OEM equipment headed overseas without switching to a second holder platform.
5) What amp ratings does the Bussmann CHM holder come in?
The CHM series spans 1A to 30A. Orderable ratings include 1A (CHM1DCU), 2A (CHM2DCU), 3A (CHM3DCU) and 30A (CHM1DCIU). Pick the holder rating at or above the fuse you intend to install, not above the circuit's protection requirement.
6) How much panel space does a Bussmann CHM fuse holder take up?
Each pole measures 2.91 in. high by 3.28 in. wide and weighs .22 lb. Lay out your DIN rail or backplane on that width per pole when you're ganging several together, and allow clearance in front for the fuse carrier to swing out.
7) Do I get the fuse with the CHM holder, or do I order that separately?
The CHM is the fuse holder itself, not a fuse assembly. Order the fuse element separately to match the holder's amp rating, the circuit voltage (up to 600 Vac or 1000 Vdc) and the interrupting rating you need. Holder amp rating is a maximum, so a 30A CHM will accept smaller fuses within its class.
8) Where does a modular fuse holder like the CHM make more sense than a fused disconnect switch?
A modular holder like the CHM is for inside the enclosure: power distribution panels, motor control centers, switchgear and OEM panel builds where you want per-circuit fusing that a technician can pull and replace without dismantling the assembly. A fused disconnect is what you use when the circuit also needs a visible, lockable means of disconnect at the equipment. Many jobs use both, the disconnect at the feeder and CHM holders on the control and branch circuits behind it.
