SKU CH-8KAG-FNDYP

Glass time-delay fuse rated 750 mA at 250 V AC with a 10 kA interrupt rating at 125 V AC, 5 × 20 mm, pack of 5

  • Time-delay glass fuse handles temporary surges without nuisance trips
  • 10 kA interrupt rating at 125 V AC clears high fault currents safely
  • 35 A interrupt rating at 250 V AC protects 250 V circuits
  • CE, CSA Class 1422-01 and UL 248-14 certifications confirm safety compliance
  • Pack of 5 fuses sized 20 mm x 5 mm fits standard GMC holders

What the fuse protects

The Bussmann GMC-750-R is a 5 mm × 20 mm glass time-delay fuse rated at 750 mA and 250 V AC. It suits technicians and hobbyists who need reliable over-current protection for low-power circuits in equipment such as instruments, chargers or small appliances.

Interrupt rating at your voltage

At 125 V AC the fuse safely breaks 10 kA, while at 250 V AC the rating is 35 A. Choose this part only when the prospective short-circuit current in your application stays within those limits; higher fault currents demand a fuse with a greater interrupt capacity.

Pack of five and cross-reference data

The box contains five identical fuses, giving spares for service calls or multiple units. Equivalent series include Littelfuse 239 and Mersen GSC, and the fuse fits HTB-series fuse blocks, simplifying sourcing when the original branding is unavailable.

Questions about this item

What does the 750 mA rating mean when the fuse is installed in a circuit?

The fuse will carry up to 750 mA continuously and open the circuit if the current exceeds that value for the time-delay period.

What does the 10 kA interrupt rating at 125 V AC actually limit?

It means the fuse can safely break a fault current of up to 10 kA at 125 V AC without rupturing; at 250 V AC the interrupt rating is 35 A.

Will the 5 mm diameter by 20 mm length body fit a standard 5 x 20 mm fuse holder?

Yes, the cylindrical glass body measures 5 mm in diameter and 20 mm long, matching the common 5 x 20 mm fuse block series HTB.
