Bussmann BK/HLS-07-SL – Frequently Asked Questions
1) What fuses does the Bussmann BK/HLS-07-SL fuse holder take?
The BK/HLS-07-SL is built for GMT indicating fuses. GMT alarm-indicating fuses pop a visible flag when they open, so a telecom technician can spot the blown circuit on the panel without pulling every fuse. Order the GMT fuse amperage separately to match each circuit; the holder itself is rated to 15A.
2) Can I use this 7-pole Bussmann fuse holder on a 48V DC telecom power plant?
Yes. The BK/HLS-07-SL is rated 125 Vac, 60 Vdc, so a nominal 48V DC telecom plant sits inside its DC rating. It was made for telecommunications DC power circuit protection, which is the typical -48V central office and cabinet application. Do not run it above 60 Vdc.
3) How does the BK/HLS-07-SL mount, and what are the terminals like?
It is a panel-mount unit, dropped into the equipment panel rather than DIN rail or chassis screwed. Connections are tin-plated bifurcated copper terminals with a 0.135 inch short lead, which keeps the depth behind the panel tight in a crowded DC distribution frame.
4) Can I put a 20A fuse in the Bussmann BK/HLS-07-SL?
No. The holder is rated 15A, so 15A is the ceiling per position regardless of what GMT fuse will physically seat. Size each GMT fuse at or below 15A and within the 125 Vac / 60 Vdc rating of the holder.
5) How many circuits does the Bussmann BK/HLS-07-SL protect?
Seven. It is a seven-pole holder, so one panel-mounted unit carries seven separate GMT fuse positions. That is the appeal for DC distribution panels: seven circuits fused from a single cutout instead of seven individual holders.
6) Is the short-lead version the right one for my panel, or do I need long leads?
The BK/HLS-07-SL is the short-lead variant, with 0.135 inch leads on the tin-plated copper terminals. That suits a panel where wiring is landed close behind the face and space is tight. If your build needs extra lead length to reach a terminal block or bus, a short-lead holder will force splices, so spec a longer-lead HLS holder instead.
7) Will the Bussmann BK/HLS-07-SL hold up in a hot equipment cabinet?
The body is thermoplastic and the terminals are tin-plated copper, a combination chosen for corrosion resistance and low contact resistance in enclosed electrical panels. It is an indoor panel component for telecom DC power gear, not a wet-location or outdoor-exposed device.
8) What is the exact part number to order for the Bussmann 7-pole GMT fuse block?
Bussmann part number BK/HLS-07-SL. The BK prefix is Bussmann's packaged line, HLS is the fuse holder series, 07 is the seven-pole count and SL denotes the short lead. Shipping weight is listed at 5.5 lb.
