Five glass cylindrical fuses with metal end caps

Bussmann

Bussmann GMC-150-R Glass Fuse 150mA 250V AC 5 Pack

SKU CH-HBAV-RG0XT

Pack of five glass time-delay fuses rated 150 mA at 250 V AC with 10 kA interrupt at 125 V AC and 35 A at 250 V AC

  • Time-delay protection prevents nuisance blows
  • 150 mA rating suits low-current circuits
  • 250 V AC rating fits mains-voltage equipment
  • 10 kA interrupt at 125 V AC handles high fault currents
  • Pack of 5 fuses provides ready spares

Glass Fuse 150mA 250V AC 5 Pack

The Bussmann GMC-150-R is a glass-bodied cylindrical fuse rated at 150 mA and 250 V AC. It suits technicians and hobbyists protecting low-current circuits in appliances, instrumentation or control gear. The time-delay characteristic tolerates brief inrush currents without nuisance opening. Five pieces come in one pack.

Interrupt Rating 10kA at 125V AC 35A at 250V AC

The decisive figure is the interrupt rating: 10 kA at 125 V AC and 35 A at 250 V AC. This tells you the maximum prospective fault current the fuse can safely break at each voltage. Select this part only when your circuit’s available fault current stays at or below those values.

20mm x 5mm Cylindrical Non-Rejection Fit

The fuse measures 20 mm long by 5 mm diameter and uses a non-rejection body style. It fits standard 5 × 20 mm fuse holders or blocks such as the HTB series. No special rejection feature is present so the holder must accept a plain cylindrical cap. The glass body allows visual inspection of the element after a fault.

Questions about this item

What does the 150 mA rating mean when the fuse is installed in a circuit?

The fuse will carry up to 150 mA continuously and will open if the current exceeds that value for a sufficient time, protecting the downstream wiring and components.

What does the interrupt rating of 10 kA at 125 V AC and 35 A at 250 V AC cap in practice?

It defines the maximum prospective short-circuit current the fuse can safely interrupt at those voltages; above those levels the fuse may not clear the fault without damage.

What physical dimensions and mounting style does this fuse need to fit a holder?

It is a cylindrical glass fuse 20 mm long and 5 mm in diameter, non-rejection style, compatible with HTB series fuse blocks.
