Eaton HM60400-2CR HM modular fuse block - UL Listed
Part Number: HM60400-2CR
Quick Summary
The Eaton HM60400-2CR HM modular fuse block is a compact protection solution for industrial power distribution and motor control panels. It combines a rugged two-pole design with Class K and Class H compatibility to support a broad fuse library while minimizing panel footprint. Engineers often struggle to find blocks that meet both high short-circuit requirements and tight wiring densities without complicating serviceability; this model meets those needs with a 225–400 A rating and 10 kAIC at 600 V. UL Listed and CSA Certified, RoHS compliant, and backed by Eaton’s quality standards, it delivers trusted compliance across North American facilities. Standardizing on HM60400-2CR streamlines panel assembly and reduces maintenance surprises through familiar Bussmann components.

Eaton Specification Sheet - HM60400-2CR
Two-pole HM60400-2CR design enables compact installation and straightforward fuse integration. The business impact is a lighter panel footprint and faster wiring, translating to reduced assembly time for panel builders and lower labor costs in the field. This configuration is ideal for industrial control panels and motor protection where space is at a premium. The 225–400 A amperage range paired with a 600 V rating and a 10 kAIC short-circuit capability delivers robust fault protection, improving safety margins and reducing downtime from fault events. In practice, engineers can select Class K or Class H fuses without redesigning enclosures, enabling rapid retrofits and standardized maintenance across multiple lines. RoHS compliance and UL Listed/CSA Certified assurances support regulatory alignment while keeping procurement straightforward for value-focused buyers. Compatibility with the Bussmann HM fuse family ensures interchangeability and a common spares strategy, reducing inventory risk and supporting lean maintenance programs.

FAQs
Install the HM60400-2CR as a two-pole block within the panel enclosure, ensuring a dedicated space for the 12 in length, 7.25 in width, and 4.75 in height. Use appropriately rated conductors sized for 225–400 A and keep clearances for 600 V operation. Torque connections per the Eaton specification, and group-fuse wiring to minimize cross-talk. The design supports standard Bussmann HM fuses, simplifying stocking and replacement.
The unit provides 225–400 A amperage rating, 600 V voltage rating, and a 10 kAIC short-circuit rating. When selecting fuses, choose a class K or class H fuse within that amperage window to ensure coordinated protection. This enables reliable fault interruption without nuisance tripping, compatible with typical industrial loads and motor starters in panel assemblies.
Yes. The HM60400-2CR is designed as a modular fuse block compatible with Class K and Class H fuse configurations. Its two-pole design and standard Bussmann HM series support seamless retrofits, allowing you to maintain existing protection schemes without enclosure modifications while benefiting from a unified spare part strategy.
The HM60400-2CR is UL Listed and CSA Certified, with RoHS compliance confirmed. These certifications support regulatory requirements in North American facilities and help streamline supplier qualifications, audits, and sustainability reporting for your electrical protection strategy.
Benefits include reduced panel footprint, faster assembly due to standardized HM series components, and simplified maintenance with interchangeable fuses. The high short-circuit rating and broad amperage range reduce downtime from faults, while RoHS and third-party certifications help avoid compliance costs. Overall, you gain predictable performance, lower spare-part inventory, and faster time-to-production in manufacturing environments.
