CR
Its 100 A amperage rating with a single-pole design at 250 V provides targeted protection for feeders and control circuits. This configuration reduces the risk of nuisance tripping while enabling precise fusing for critical loads. The compact footprint also eases panel layout and cabling strategies, supporting faster installation and easier inventory management for automation projects. With a 10 kA short-circuit rating, the HM25100-1CR offers a robust fault withstand in higher fault current environments, boosting safety margins in switchgear and motor control centers. This resilience translates to fewer protective failures and more reliable uptime, especially in demanding applications such as conveyors and process lines where transients are common. The rating aligns with common industrial protection schemes, helping engineers select fuses without over- or under-protecting circuits. UL Listed, CSA Certified, and RoHS Compliant marks help you meet regulatory requirements and pass third-party audits. By aligning with these standards, the block minimizes compliance overhead during equipment builds and reduces the risk of late-stage design changes during commissioning. The RoHS focus supports sustainability initiatives while ensuring compatibility with a broad range of components in mixed-supply panels. CR designation indicates compatibility with the Bussmann HM modular system, enabling efficient replacement and consistent performance across the protection block family. The compact footprint and standardized mounting support straightforward installation in tight control panels, while maintaining compatibility with existing fuses and accessories. This cohesive ecosystem reduces spare-parts variety and speeds up maintenance workflows for OEMs and field engineers. Engineered for ease of installation, the HM25100-1CR supports fast field service, reduces maintenance time, and lowers total cost of ownership in preventive maintenance programs. Its rugged construction and clear labeling help technicians identify and replace fuses quickly, cutting downtime in high-volume production lines. For system integrators, sourcing from a single, proven HM family simplifies procurement and improves overall equipment reliability.

FAQs
To install, mount the HM25100-1CR into the HM Bussmann modular system, connect the line and load per the panel’s wiring diagram, and verify 250 V rating and 100 A capacity. The one-pole design simplifies wiring and fuse selection, and compatibility with existing HM components streamlines procurement and maintenance. Always follow lockout-tagout procedures and confirm fault-level alignment.
The fuse block supports 100 A continuous operation with a 250 V rating and a 10 kA short-circuit rating. This combination ensures robust protection for feeders and control circuits while minimizing nuisance trips under normal loads. Coordinate fuse type and rating with conductor sizes and upstream protection to optimize safety and uptime in automated lines.
Yes, but ensure secure mounting and proper strain relief of conductors to prevent movement that could affect contacts. The compact one-pole design reduces mechanical stress on the fuse block, and by using appropriate hardware and enclosure mounting, you can maintain reliable operation in vibration-heavy applications such as packaging or conveying lines.
UL Listed and CSA Certified marks confirm compliance with established safety standards, facilitating regulatory approvals and customer audits. RoHS compliance further ensures environmental responsibility and broad component compatibility. Together, these certifications reduce risk during design reviews and commissioning for control panels in industrial settings.
ROI stems from reduced downtime due to fast fuse replacement, simplified stocking with a single HM family, and lower maintenance costs from reliable protection. The 100 A, 250 V rating supports scalable protection for multiple lines, while UL/CSA/RoHS compliance minimizes commissioning and compliance risks, delivering predictable, long-term equipment uptime.
