Three-Pole Class R Fuse Block

The Eaton Bussmann RM60030-3SR is an open fuse block rated for 600 V AC/DC and a 0 to 30 A range. It accepts Class R fuses up to 5 in length and 13/16 in diameter across three poles. The transparent thermoplastic body uses screw connectors for 18 to 10 AWG wire.

Bolt-Down or DIN Rail Mounting

Mount the block directly with bolts or clip it onto standard DIN rail to fit panel layouts. The open design leaves fuse links visible for quick inspection without removing a cover. Each pole handles the same voltage and current rating, simplifying three-phase or multi-circuit wiring.

Replaces Enclosed or Lower-Voltage Blocks

This unit suits installs that need 600 V Class R protection in a compact 7.2 in by 3.5 in footprint. It is not for applications requiring built-in indication, covers, or fuse classes other than Class R. Builders needing higher ampacity or different fuse series should specify another block.

Questions about this item

What is the maximum continuous current this three-pole block can carry before the Class R fuse opens?

The block is rated for 0 to 30 A and accepts Class R fuses up to 30 A, so sustained loads above 30 A will cause the fuse to interrupt the circuit.

How much heat does the block dissipate when it carries 30 A all day?

The thermoplastic body and open design rely on natural convection; no temperature-rise or watt-loss figures are published for continuous 30 A operation.

Which conductors and mounting hardware must I already have to install it?

You need 18 to 10 AWG wire for the screw terminals and bolts for the mounting feet; an optional cover is sold separately.
