Five cylindrical glass fuses with silver metal end caps

Bussmann

Bussmann AGC-4-R 4A Fast Acting Cylindrical Glass Fuse 250VAC 5PK line protection

SKU CH-8QAX-BXS3H

Pack of five 4 A fast-acting glass fuses rated 250 V AC with 10 kA interrupt at 125 V

  • 4 A rating protects low-current circuits
  • Fast-acting glass element clears faults quickly
  • 250 V AC rating suits mains-powered equipment
  • 10 kA interrupt capacity at 125 V AC handles high fault energy
  • 200 A interrupt capacity at 250 V AC ensures safe break under load

Bussmann AGC-4-R 4A Glass Fuse Pack

This pack contains five Bussmann AGC-4-R fast-acting cylindrical glass fuses rated at 4 amps and 250 volts AC. They provide overcurrent protection for electrical circuits in automotive, generator and general low-voltage equipment. Each fuse features a 1-1/4 inch by 1/4 inch glass body with a 10kA interrupt rating at 125V AC and 200A at 250V AC. The non-rejection design fits standard AGC-compatible fuse blocks.

Suitable For Standard Fuse Holders

These fuses suit technicians and owners maintaining equipment that specifies AGC series 4A glass fuses in compatible blocks such as series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB or S-8000. They are not for circuits requiring time-delay or slow-blow characteristics, nor for holders that demand a rejection-style fuse. Buyers needing a higher amperage or voltage rating must select a different fuse.

Critical Specification: 4 Amp 250V AC Rating

The decisive parameter is the 4 ampere, 250 volt AC rating combined with fast-acting response. Verify that the protected circuit and the fuse block both match these electrical values and the 1-1/4 inch by 1/4 inch physical envelope before installation. Using a fuse with different current, voltage or speed characteristics compromises circuit protection.

Questions about this item

Which version of the AGC-4-R fuse pack should I choose for a standard 4 A circuit?

This pack contains five identical 4 A, 250 V AC fast-acting glass fuses, so a single pack covers the requirement.

What does the 10 kA interrupt rating at 125 V AC mean once the fuse is installed?

It means the fuse can safely break a fault current up to 10 kA at 125 V AC without rupturing.

What does the non-rejection cylindrical body cap in practice regarding fuse-block fit?

The 1-1/4 in by 1/4 in cylindrical body fits standard AGC-compatible blocks such as series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000.
