Bussmann CHM1 Fuse Holder Block 30A 600V 1-Pole

The Bussmann CHM1 fuse holder is a compact, single-pole DIN-rail module that accepts Bussmann MFH midget fuses and protects circuits up to 30 A at 600 V. It is rated 600 V (UL) and 690 V (IEC), with a 30 A UL rating and 32 A IEC rating, making it suitable for control panels and industrial equipment where a dedicated fuse block is required. As part of the CHM modular fuse holder family, the CHM1DIU variant lists 600 V UL, 690 V IEC ratings and single-pole operation for MFH fuses, and the unit mounts on standard DIN rails for easy integration into panel layouts. This 1-pole block is designed to house a Bussmann MFH fuse, enabling fast replacement and minimal downtime in applications such as machine controls, power distribution, and HVAC or process equipment. The short-circuit current rating is limited by the installed fuse, up to 200 kAIC depending on the fuse selected, ensuring protection is matched to the circuit’s needs while staying within the device’s voltage and current limits.
