FAQs
Yes. The HM25100-3CR is part of Eaton's Bussmann HM family and is designed for seamless compatibility with other HM modular fuse blocks. Its three-pole configuration, Class H/K protection, and CR feature simplify panel planning and allow straightforward cross‑reference when upgrading or expanding existing installations.
The unit is rated for 70–100A, 250V, with a 10 kA short‑circuit rating. This enables protection of mid‑ to high‑current circuits in control panels and MCCs without needing multiple devices. Designers benefit from reduced part count, faster assembly, and predictable fault protection aligned with typical industrial power distributions.
Absolutely. The HM25100-3CR is a three‑pole fuse block intended for three‑phase protection, supporting Class H and Class K types. Its 70–100A range covers common motor drives and control feeders, while the 10 kAIC rating provides robust fault protection in moderately aggressive manufacturing environments.
The HM25100-3CR carries UL Listed and CSA Certified markings and is RoHS compliant. These certifications facilitate international procurement, regulatory approvals, and sustainable manufacturing practices, helping ensure compliance across global supply chains and reducing qualification time for OEMs.
Using the HM25100-3CR reduces spare parts and simplifies maintenance with a modular, replaceable component set. Its compatibility within the HM family means quicker part sourcing, faster commissioning, and lower lifecycle costs due to fewer mismatched protections and streamlined stocking for service teams.
