Five glass cylindrical fuses, silver end caps, 20mm by 5mm

Bussmann

Bussmann GMC-80-R Glass Fuse 80mA 250V AC Time-Delay 5 PK

SKU CH-B9DT-D7T0V

A pack of five 20 mm glass time-delay fuses rated 80 mA at 250 V AC with a 35 A interrupt rating at that voltage

  • Time-delay protection handles temporary surges without nuisance trips
  • 80 mA rating at 250 V AC suits low-current circuits
  • 10 kA interrupt rating at 125 V AC clears high faults safely
  • 20 mm × 5 mm glass body fits standard 5×20 mm holders
  • Pack of 5 fuses provides ready spares for maintenance

Circuit protection for low-current AC circuits

This pack contains five glass-bodied time-delay fuses rated at 80 mA and 250 V AC. They suit equipment that needs a slow-blow response to tolerate brief inrush currents without nuisance opening. The cylindrical 20 mm by 5 mm form factor fits standard fuse holders used in instrumentation, control panels and small appliances.

Interrupt rating defines safe application

Each fuse will safely interrupt up to 10 kA at 125 V AC or 35 A at 250 V AC. This rating is the single figure that tells you whether the fuse can clear a fault on your supply without rupturing. Circuits with prospective fault currents above these values need a different protection device.

Five-piece pack supports spares and multi-point use

The quantity lets you protect several identical circuits or keep replacements on hand for maintenance. No additional hardware, software or mounting accessories are included in the package.

Questions about this item

What does the 80 mA rating mean when the fuse is installed in a circuit?

The fuse will carry up to 80 mA continuously and open after a time delay if the current exceeds that value, protecting downstream components from sustained overloads.

How do the 10 kA at 125 V AC and 35 A at 250 V AC interrupt ratings limit what the fuse can safely break?

At 125 V AC the fuse can interrupt fault currents up to 10 kA, while at 250 V AC it is rated to break only 35 A, so the voltage of the circuit determines the maximum prospective short-circuit current it can handle.

What physical dimensions and mounting style does the 20 mm by 5 mm cylindrical glass body require?

The fuse fits a standard 5 × 20 mm cylindrical holder or clip; its non-rejection glass body slides in without a keyed block and is compatible with HTB series fuse blocks.
