FAQs
To install the HM25030-2QR, mount the two-pole block securely in a suitable panel location, connect conductors aligned with the 0–30 A rating, and select the Class H or Class K fuse links as required by your protection scheme. Ensure compatibility with the HM series fuses, maintain proper clearance for airflow, and follow all applicable safety standards during wiring and commissioning.
The 10 kAIC rating indicates the fuse block can interrupt fault currents up to 10 kiloamps without sustaining damage. This rating provides a safety margin for demanding industrial circuits, such as motor starters or drives, reducing the risk of catastrophic fuse failure and improving system reliability when protecting feeders and control circuits against surges.
Yes. The QR feature enables rapid fuse replacement, minimizing downtime during maintenance. Regulatory certifications like UL Listed and CSA Certified confirm conformance to recognized safety standards, while RoHS compliance ensures restricted hazardous substances are not present. Together, these aspects streamline procurement, installation, and ongoing compliance for regulated facilities and high-availability systems.
The HM25030-2QR is rated for 250 V in typical industrial AC protection applications and is designed for general automation panels. For DC systems, verify the specific fuse class and device rating with Eaton documentation and ensure DC operation is within approved limits before deployment in DC-powered equipment.
Using the HM25030-2QR can lower total cost of ownership by reducing maintenance downtime, speeding fuse changes with QR technology, and ensuring compliant protection with UL and CSA listings. Its compact form reduces panel space, while the 0–30 A range supports flexible protection without oversizing, delivering safer, more reliable automation with predictable budgeting.
