Bussmann 170H3030 – Frequently Asked Questions

1) What is the Bussmann 170H3030 and what job does it do in a fuse assembly?
The Bussmann 170H3030 is a high-speed microswitch sold as a fuse accessory, configured as Switch K1. It mounts with a fuse-link that uses a type K indicator and gives a contact output so a panel or control circuit can see when the fuse has operated. The switch itself does not carry load current, it signals status.
2) Will the 170H3030 microswitch work on a 690V IEC or 700V UL fuse system?
Yes on both. The 170H3030 carries a voltage rating of 700 V to UL and 690 V to IEC, so it suits high-speed fuse systems at those levels. Note the switch contacts themselves are a separate, much lower rating of 2 A at 250 VAC, so the signalling circuit you wire to it must stay within that.
3) Is the 170H3030 a fuse, or do I still need to buy the fuse separately?
It is an accessory, not a fuse. The 170H3030 supplies no overcurrent protection on its own; it is the K1 microswitch that reports the state of a type K indicating fuse-link. You order the high-speed fuse for your 700 V UL / 690 V IEC system separately and add this switch for monitoring.
4) What can I actually switch with the 170H3030 contacts, a relay coil or a load?
Signal-level only. The contacts are rated 2 A at 250 VAC, which suits a relay coil, PLC input, alarm or indicator lamp. Do not use it to break motor or feeder current. The 5 A figure in the manufacturer amperage field is a separate rating and should not be treated as a contact switching capacity for a load circuit.
5) Does the Bussmann 170H3030 have a visual blown-fuse indicator?
No. The 170H3030 is non-indicating, so there is no pop-up pin or flag to look at on the switch itself. Status comes back electrically through the microswitch contacts, which is why it pairs with a fuse-link carrying a type K indicator. If your crew relies on walking the panel and eyeballing a flag, you need an indicating fuse in the holder as well.
6) How much space do I need in the enclosure for the 170H3030 microswitch?
Allow for 212 mm length/depth by 94 mm width by 82 mm height. It weighs 139.6 g, light enough that it adds nothing meaningful to a DIN rail or panel mounting. The 212 mm dimension is the one that usually decides whether it clears the door or gutter space in a shallow panel.
7) What part number do I order for the K1 high-speed fuse microswitch?
Order Bussmann 170H3030. That single Eaton Bussmann part number covers the K1 microswitch configuration; there are no finish, size or rating options to specify with it.
