Bussmann RS20F – Frequently Asked Questions

1) What fuse links does the Bussmann RS20F fuse holder take?
The RS20F is built for British standard NITD and NIT fuse-links. It won't accept North American Class CC, midget, or J fuses, so if your panel drawing calls for a UL class fuse, this is the wrong holder.
2) Is the Bussmann RS20F rated high enough for a 690V control panel circuit?
Yes. The RS20F carries a 690 V rating at 20 A on a single pole, which covers 400/415 V and 690 V low voltage industrial circuits. Don't load it past 20 A.
3) I need three-phase protection. Does one RS20F cover all three legs?
No. The RS20F is a single-pole holder, one fuse-link per unit. For a three-phase feeder you'd order three of them (or four if you're fusing the neutral) and gang them on the plate.
4) How much panel space does the RS20F fuse holder need?
Allow for 84 mm height, 112 mm length/depth, and 38 mm width. The 112 mm depth figure is the one that usually bites, so check your enclosure depth behind the DIN rail or mounting plate before committing to a tight layout. It weighs 213.4 g, so it needs no extra bracing.
5) Can the Bussmann RS20F be mounted directly on busbar?
No. The RS20F is not a bus-mounting holder, so it has to be fixed to a panel or mounting plate and wired in, not clipped onto live bus. For busbar-mounted protection you need a holder specifically listed as bus mount.
6) Does the Bussmann RS20F come with a fuse-link included?
No. The RS20F is the holder only, a fuse accessory. You order the NITD or NIT fuse-link separately, sized to the circuit at or below the holder's 20 A rating.
7) What is the exact part number to order for the Bussmann British standard 20A fuse holder?
Order Eaton Bussmann RS20F. That single model number is the whole configuration: 690 V, 20 A, single-pole, for BS NITD/NIT fuse-links. There are no finish or option codes to add.
