Bussmann BMM603-3PQ – Frequently Asked Questions

1) What fuses does the Bussmann BMM603 fuse block take?
The BMM603 holds Midget-style fuses (13/32 x 1-1/2 inch class), rated up to 600V and 30A. It will not accept Class CC fuses with rejection features, standard ferrule fuses of other body sizes, or blade-style fuses. If your circuit needs Class CC rejection, you need a CC-rated block instead.
2) What is the difference between the BMM603-3S, BMM603-3PQ and BMM603-3SQ?
All three are the same three-pole 600V/30A Midget fuse block; the difference is only the wire termination. BMM603-3S is screw type, BMM603-3PQ is pressure plate quick connect, and BMM603-3SQ is a screw/quick-connect combo. Choose screw for field-wired conduit terminations, quick connect for OEM harness work, and the combo when you need both on the same block.
3) What wire size can I land on this Bussmann fuse block, and what torque?
The screw terminals on the BMM603 take #18 to #11 AWG copper, torqued to 20 lb-in. That covers the usual 14 and 12 AWG control and branch wiring in a panel. Anything heavier than 11 AWG needs a larger block.
4) Is this three-pole block suitable for protecting a three-phase motor branch circuit?
Yes. The three-pole BMM603 puts three Midget fuses in one block at 600V and 30A, which suits three-phase branch and motor control circuits in industrial control panels and motor control centers. Each pole is fused separately, so you size the Midget fuse in each leg to the load.
5) What short circuit current rating does the Bussmann BMM603 carry?
200 kA short circuit rating, with 200 kA impulse withstand voltage. That covers high available fault current services where the block sits downstream of a large transformer.
6) Do I need a cover to finger-safe these terminals?
The BMM603 works with the CVR-CCM and CVRI-CCM accessory covers for terminal protection. Covers are ordered separately from the block.
7) Is the BMM603 UL Listed or UL Recognized?
UL Recognized, and RoHS compliant. Recognized components are intended for use inside a larger listed assembly such as an industrial control panel, which is where this block is normally installed.
8) Can this fuse block go in a hot enclosure or an unheated outdoor cabinet?
Operating range is -20 C to 120 C, so it handles unheated winter cabinets and hot panel interiors. Remember the fuse itself and the enclosure derating still govern continuous current at high ambient.
