Two-pole fuse block for industrial fuses
The Bussmann RM25030-2CR accepts Class R fuses up to 30 amps at 250 volts AC or 125 volts DC. It suits panels that need two protected circuits in a single bolt-down or DIN-rail mount. The thermoplastic body holds box-lug terminals for 14 to 2 AWG wire. Dimensions are 3.20 inches long by 2.00 inches wide by 2.00 inches high.
Steady thermal performance under continuous load
The open design allows air to circulate around the fuse elements during sustained operation. Box-lug connections maintain low resistance when tightened to the correct torque. The 250 VAC and 125 VDC ratings apply to continuous duty, not only momentary peaks. Thermoplastic insulation retains its properties at the temperatures reached by fully loaded 30-amp fuses.
Check fuse series and mounting before ordering
Verify that the replacement fuses belong to the FRN, FRS, KTN-R, KTS-R, LPN or LPS series used with the RM250 range. Confirm the panel has either bolt-down holes or a standard DIN rail for the specified mounting style. Ensure the wire gauge falls within the 14 to 2 AWG range accepted by the box lugs. The two-pole layout requires space for both circuits side by side.

Questions about this item
How hot does the RM25030-2CR get when carrying 30 A continuously?
The thermoplastic body is rated for the listed 30 A at 250 VAC and 125 VDC; no separate temperature-rise figure is published.
What wire and tools do I need to install the box-lug terminals?
The block accepts 14 to 2 AWG copper wire; a screwdriver or nut driver suited to the lug screws is required.
Will the two-pole RM25030-2CR fit on the same DIN rail as my older single-pole holders?
It mounts by bolt-down or DIN rail; the 2.00 in. width matches common rail spacing, but pole-to-pole alignment varies by brand.
