Bussmann 12BFGHA80 – Frequently Asked Questions

1) Is the 12BFGHA80 a bolt-in fuse-link or does it clip into spring contacts?
Bolt-on construction, single barrel, cylindrical body. It fastens into the fuse base rather than snapping into clips, so your mounting needs matching bolt-fixing centres. The fuse-link body measures 359 x 76.2 mm.
2) What short-circuit level can an 80A 12kV back-up fuse-link interrupt?
40 kAIC. That is the breaking capacity you compare against the prospective fault current at the point of installation, and it covers most 12 kV distribution substations. The element is silver, which is what gives repeatable time-current behaviour clearing those faults.
3) Does this Bussmann medium voltage fuse-link have a striker to trip the switch when it blows?
Yes, the 12BFGHA80 is supplied with a striker. In a fuse switch combination unit the striker gives mechanical blown-fuse indication and is what operates the switch trip, so all three phases are opened when one link clears. If your base is not arranged for striker operation you still get the visual indication.
4) I need to replace a blown 80A link in a 12kV fuse switch - do I have to change all three phases?
Standard substation practice is to replace the full set of three, because the surviving links have seen the same fault current and their elements may be partly damaged. The 12BFGHA80 is an 80 A, 12 kV bolt-on back-up link with a striker, so order three identical links and confirm the part number stamped on the one you are removing matches before fitting.
5) How heavy is the 12BFGHA80 and what are the shipping dimensions?
Roughly 3.98 kg (3982 g) per fuse-link, packed in standard packaging measuring 390 mm long by 270 mm wide by 80 mm high. Useful if you are stocking spares on a substation shelf or planning a freight consignment of several links.
6) What is the cold resistance of the 12BFGHA80 fuse element?
Published resistance is 9.73 ohms. Commissioning engineers use that figure as the reference when ohming out a newly installed link or checking a suspect one in a three-phase set; a reading well off that value points to a damaged element even if the striker has not operated.
