Bussmann CHM1DIU Single-Pole Modular Fuse Holder, 600V/30A UL

The Bussmann CHM1DIU is an Eaton Bussmann series CHM modular fuse holder engineered for single-pole fuse installations in industrial, commercial, and OEM electrical systems. This modular fuse holder is rated 600V (UL) and 690V (IEC), with a current rating of 30A (UL) and 32A (IEC), delivering dependable overcurrent protection within Eaton's CHM modular fuse holder platform. The single-pole configuration supports flexible, space-saving panel layouts, allowing electrical designers to build out multi-pole fuse assemblies using individual CHM1DIU modules as needed. Backed by the Eaton Bussmann name, the CHM1DIU is engineered to deliver consistent, code-compliant circuit protection performance for professional electrical work.

Key Features

  • Modular Fuse Holder Design: Part of the Eaton Bussmann CHM series, the CHM1DIU allows single-pole fuse holder modules to be combined into larger multi-pole fuse holder assemblies for custom panel and enclosure configurations.
  • Single-Pole Configuration: Designed as a single-pole fuse holder, the CHM1DIU simplifies installation in applications where individual pole protection and modular assembly are required.
  • Dual Voltage Rating: Rated 600V (UL) and 690V (IEC), the CHM1DIU supports compliance with both UL and IEC electrical distribution standards for domestic and international projects.
  • Dual Amperage Rating: Rated 30A (UL) and 32A (IEC), sized to protect circuits operating within these current limits.
  • Compact Modular Footprint: The CHM series modular fuse holder design is built for space-efficient mounting within panelboards, enclosures, and control equipment.
  • Flexible System Integration: The single-pole CHM1DIU module can be paired with additional CHM series fuse holders to build two-pole or three-pole fuse holder assemblies as project requirements dictate.
  • Eaton Bussmann Engineering: Manufactured under the Eaton Bussmann brand, a recognized name in circuit protection components for industrial and commercial electrical systems.
  • Dependable Overcurrent Protection: The CHM1DIU is engineered to provide reliable fuse holding for overcurrent protection in electrical distribution circuits.

Bussmann CHM1DIU – Frequently Asked Questions

1) What voltage and amperage can the Bussmann CHM1DIU fuse holder be used at?
The CHM1DIU is rated 600V and 30A under UL, and 690V/32A under IEC. Pick the rating set that matches the standard your panel is built to: a UL-listed North American installation works to the 600V/30A figures, and the higher IEC numbers apply only on IEC-rated equipment. It will not cover a circuit above those limits.
2) Can I use the CHM1DIU on a three-phase circuit?
Only by ganging modules. The CHM1DIU is a single-pole holder, so a three-phase feeder needs three of them mounted side by side (or two for a two-pole circuit). That is how the CHM series is intended to be used: build the pole count you need from individual modules rather than buying a fixed multi-pole block.
3) Is a fuse included with the Bussmann CHM1DIU?
No. The CHM1DIU is the holder only. You order the fuse separately, sized at or below 30A for a UL installation, and it must be the class and body size the CHM series carrier accepts.
4) Is the CHM1DIU the right part number to repeat for a multi-pole assembly?
Yes. The Bussmann manufacturer part number is CHM1DIU, and because each unit is one pole, you simply order the quantity that matches your pole count. Keeping one number across a panel also simplifies spares stocking for maintenance crews.
5) Will a 600V fuse holder work on a 480V motor circuit?
Yes. A holder's voltage rating is a maximum, so the 600V UL rating covers 480V three-phase and anything below it. For a 480V motor circuit you would use three CHM1DIU modules, one per phase, with fuses sized for the motor at 30A or less.
6) Where does a CHM series modular fuse holder get used?
Typical placements are industrial and commercial panelboards, motor control centers, enclosure and panelboard wiring, and OEM electrical equipment. It suits any spot where you want individual pole protection and a compact footprint rather than a fixed multi-pole fuse block.
