Bussmann CHM2DIU Modular Panel-Mount Fuse Holder

Bussmann CHM2DIU Modular Panel-Mount Fuse Holder

The Bussmann CHM2DIU is a modular fuse holder engineered to provide dedicated, serviceable fuse protection within control panels, machine enclosures, and other industrial or commercial electrical assemblies. This product page covers the CHM2DIU family, which is offered across a Voltage Rating / Number of Poles selection ranging from a 48 Vdc 1-Pole configuration up to a 600 V (UL) / 690 V (IEC) 2-Pole configuration, giving panel builders a single modular fuse holder platform that scales from single-pole low-voltage circuits to higher-voltage, two-pole applications. Regardless of the specific voltage/pole option selected, every CHM2DIU shares the same modular housing design, dedicated fuse-mounting concept, and serviceable format. Its modular design lets electricians and panel builders mount the holder directly alongside other modular fuse holders, terminal blocks, and control components, helping keep panel layouts organized and space efficient. As a fuse holder, the CHM2DIU is intended to accept a compatible cartridge fuse, giving maintenance personnel a clear, accessible point to inspect, test, or replace the fuse without disturbing surrounding wiring. Bussmann offers the CHM2DIU as part of its broader modular fuse holder lineup, giving panel builders and specifiers a consistent, building-block approach to laying out circuit protection within a control panel.

Key Features

• Voltage / Pole Range: Available from 48 Vdc, 1-Pole up to 600 V (UL) / 690 V (IEC), 2-Pole, allowing one modular platform to cover multiple circuit-protection needs.
• Modular Construction: The CHM2DIU's modular housing allows it to be positioned side-by-side with other modular fuse holders and control devices, supporting compact, organized panel layouts.
• Dedicated Fuse Holder: Provides an individual, purpose-built mounting point for a fuse, isolating fuse protection to a single, easily identified location within the panel.
• Serviceable Design: The modular fuse holder format is intended to support quick fuse access, inspection, and replacement without disturbing adjacent circuits or wiring.
• Operating Temperature: Rated for use across -20 To 120 degrees celsius, supporting a wide range of panel and enclosure environments.
• Panel-Building Consistency: As part of Bussmann's modular fuse holder line, the CHM2DIU is designed to work alongside like components for a uniform look and function across a control panel build.
• Space-Efficient Layout: Because the CHM2DIU is modular, it can be grouped with other same-format devices to make efficient use of panel mounting space.
• Bussmann Manufacturing: Produced by Bussmann, a long-established supplier of circuit protection components used across industrial and commercial electrical systems.
