Bussmann R25030-1CR Fuse Holder

RM25030-1CR is a 1‑pole Class R fuse block from Bussmann (Eaton Bussmann) engineered for 250 VAC operation and rated to 30 A, designed to hold Class R fuses in a single‑pole configuration. It uses box‑lug terminals and supports a range of conductor sizes commonly listed as 14 AWG up to 2 AWG (larger conductors via the lug connections), with DIN rail mounting available via an optional adapter and a thermoplastic housing for durable installation. This RM25030‑1CR belongs to Bussmann’s Class R fuse‑block family and appears in distributor catalogs under the RM25030‑1CR designation. Note that this specific part is listed as obsolete and no longer manufactured by Eaton Bussmann, so availability is limited to existing stock and secondary markets. Typical applications include protection of power circuits and control wiring in electrical distribution panels and similar assemblies that require a 250 V, 30 A Class R fuse block in a single‑pole format.
