FAQs
Install the HM25030-3CR by aligning it with the three-pole protection region in your control panel, secure mounting to the chassis, and connect conductors to the HM series fuse block terminals. Verify 250 V rating and ensure compatible Bussmann HM fuses are used. Confirm UL Listed and CSA Certified components are in place for regulatory compliance.
The unit is rated 0-30 A, 250 V with a 10 kA short-circuit rating (10 kAIC). This means it can safely interrupt fault currents up to 10,000 amps in a 250 V system, helping to protect downstream equipment and improve system reliability in industrial environments.
Best suited for industrial control panels, motor protection, servo drives, and power distribution blocks in automated lines. Its three-pole design and 0-30 A range support compact protection schemes in machine cabinets, drive interfaces, and cabinet power rails, enabling standardized protection across similar equipment.
The HM25030-3CR carries UL Listed and CSA Certified listings and RoHS compliance, ensuring regulatory alignment for many markets. These certifications support safe integration in commercial and industrial installations and help streamline supplier qualification and audits.
Because the fuse block is part of a modular HM family, you can standardize spares and simplify replacement during maintenance. Its compact footprint reduces panel space, while the 0-30 A rating and 10 kAIC protection minimize downtime and facilitate quicker commissioning, contributing to lower total cost of ownership over the system’s lifecycle.
