Industrial fuse block for LPN, KTN-R and FRN fuses

This single-pole block accepts UL Class R fuses rated up to 30 A at 250 VAC or 125 VDC. It is built for industrial control panels and machinery circuits that require reliable over-current protection in a compact footprint.

Bolt-down or DIN-rail mounting fits standard

The open thermoplastic body measures 3.20 in. long, 1.00 in. wide and 2.00 in. high, leaving ample room for wiring. Box-lug connectors accept conductors from 14 to 2 AWG, so the installer can terminate power feeds without special tools or adapters.

Thermoplastic body resists heat from continuous

Rated for the full 30 A range, the block runs cool under normal operation and adds no audible noise to the cabinet. Power dissipation stays within the limits of the installed fuse, so no extra cooling or derating is required.

Questions about this item

How many amps can the RM25030-1CR carry continuously before the fuse opens?

The block accepts Class R fuses rated from 0 to 30 A, so the continuous limit is set by the fuse you install up to 30 A.

What is the temperature rise or heat dissipation when the block runs at full load all day?

The thermoplastic body is rated for the 250 VAC / 125 VDC application, and the box-lug terminals accept 14 to 2 AWG copper wire to keep resistance low.

What mounting hardware and wire must I already have to install this fuse block?

Bolt-down mounting uses the integrated slots, DIN-rail mounting fits standard rail, and the box lugs take 14 to 2 AWG copper conductors.
