FAQs
Installing the HM60400-3CR starts with confirming system voltage up to 600 V and amperage in the 225-400 A range. Mount the unit in a suitable enclosure space, wire the three poles to the incoming distribution and load circuits, and secure fuses using the CR mounting feature for quick swaps. Confirm continuity and perform a post-installation check for proper clearance and labeling. This approach minimizes startup time and ensures reliable protection across the panel.
The HM60400-3CR is rated for 225-400 A, with a short-circuit rating of 10 kA at 600 V. This combination supports high fault currents while maintaining safe operation for industrial control panels. The rating range accommodates a variety of Bussmann class fuses (H and K types) within a single modular block, simplifying protection strategy and spare parts planning.
Yes, the HM60400-3CR is RoHS compliant. It carries UL Listed and CSA Certified markings, ensuring conformity to North American electrical safety standards. This certification suite supports regulatory audits, supplier qualification, and risk mitigation for panel builders, OEMs, and integrators deploying protection blocks in machinery and automation systems.
The HM60400-3CR is designed for three-pole protection in industrial panels and motor control centers. It is compatible with Class H and Class K fuses from the Bussmann HM series, and its CR feature facilitates rapid fuse mounting and replacement. This compatibility supports standardized protection across multiple panels, aiding procurement and inventory management for machine builders.
Choosing the HM60400-3CR delivers space-efficient integration, standardized protection with HM series fuses, and robust electrical ratings (225-400 A, 600 V, 10 kA). These attributes translate to reduced maintenance downtime, easier sourcing, and consistent compliance across projects.
