FAQs
The HM25600-3CR is designed for three-pole mounting in standard electrical panels and switchgear. Begin by verifying panel clearance and mounting space, then secure the unit to a rigid backplane or DIN rail as appropriate. Connect three load conductors to the fuse holders, align with the HM series bus connections, and ensure fuse links are correctly seated for quick replacement during maintenance.
Key specs include a 450–600 A amperage rating, 10 kAIC short-circuit rating, and a 250 V operating voltage. The unit is RoHS compliant and UL Listed with CSA certification, making it suitable for heavy-duty power distribution and compliant panel assemblies in industrial environments.
Yes. The HM25600-3CR features CR designations and is compatible with Class H and Class K fuses, enabling flexible protection schemes across three poles. This compatibility reduces spare fuse variety, simplifies procurement, and supports straightforward replacement in field service.
Document UL Listed and CSA Certified marks, along with RoHS compliance, to satisfy most North American and international panel approvals. Maintain the product catalog entry, certification PDFs, and RoHS declarations from Eaton to streamline audits, supplier qualifications, and regulatory reviews.
The modular three-pole design with standard HM components enables rapid fuse replacements, reducing downtime during maintenance. The high short-circuit rating lowers risk of cascading failures, while RoHS and multi-certification support faster procurement and commissioning, contributing to lower lifecycle costs and improved equipment uptime in manufacturing or process environments.
