Bussmann RS20H – Frequently Asked Questions

1) What fuse-links does the Bussmann RS20H fuse holder accept?
The RS20H is built for British standard NITD and NIT style fuse-links. It is not a holder for North American Class CC, Midget, or ferrule fuses, so if your panel drawing calls out a BS fuse-link by NITD or NIT designation this is the matching holder. Anything outside those two families will not seat correctly.
2) Can I use the RS20H on a 690V circuit?
Yes. The Bussmann RS20H carries a 690 V rating and a 20 A rating, which covers standard low voltage industrial distribution up to 690 V. Size the fuse-link itself to the circuit; the holder's 20 A figure is the ceiling for the link you put in it.
3) How much panel space do I need for a Bussmann RS20H fuse holder?
Allow for a body measuring 79 mm height, 55 mm length/depth, and 27 mm width. The 27 mm width is the figure that matters when you are lining up several holders side by side in a control panel, and the 55 mm depth is what has to clear behind the mounting surface plus your cable bend radius.
4) Is the RS20H a DIN rail or busbar mounting fuse holder?
It is not a bus-mounting type. The RS20H is a panel-style holder meant to be fixed directly to the panel or equipment surface, so if your assembly is built around a busbar system you need a bus-mount holder instead of this one.
5) How many circuits does one Bussmann RS20H protect?
One. The RS20H is a single-pole holder, so it takes one fuse-link and protects one circuit. For a three-phase feeder you would order three of them and gang them in the panel, or specify a multi-pole British standard holder instead.
6) Does the Bussmann RS20H come with the fuse-link included?
No. The RS20H is a fuse accessory, the holder only. The NITD or NIT fuse-link sized for your circuit is a separate order, and that link is what sets the actual protection level up to the holder's 20 A limit.
7) Which Bussmann part number should I quote for a 20A British standard fuse holder?
Order by MPN RS20H, Bussmann by Eaton. That single part number covers the whole item, 690 V, 20 A, single-pole, for NITD and NIT links, so there are no finish, size, or pole options to specify on the purchase order.
