Small glass cylinder fuse with metal end caps

Bussmann

Bussmann AGC-3/8-R Glass Fuse 0.375A 10kA 125V 35A 250V line protection

SKU CH-RTCV-N0AM8

Glass fuse rated 0.375 A with 10 kA interrupt at 125 V and 35 A at 250 V

  • Fast-acting protection clears faults quickly
  • 10 kA interrupt rating at 125 V AC handles high fault currents
  • 35 A interrupt rating at 250 V AC suits higher-voltage circuits
  • Standard 1-1/4 in × 1/4 in glass body fits common fuse blocks
  • Cross-referenced to Bussmann AGC, MMB, Littelfuse 311, 312, 3AG and Mersen GGC series

What this fuse does

The Bussmann AGC-3/8-R is a fast-acting glass fuse rated 0.375 A for low-current line protection. It interrupts 10 kA at 125 V AC and 35 A at 250 V AC, making it suitable for control circuits, instrumentation and small appliance branches.

Check your holder and voltage

Verify that the fuse block accepts a 1-1/4 in by 1/4 in cylindrical body and that the circuit voltage does not exceed 250 V AC. The non-rejection design fits standard AGC-compatible clips such as series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB or S-8000.

Cross-reference equivalents

The fuse is electrically equivalent to Bussmann MMB, Littelfuse 311, 312 and 3AG, and Mersen GGC series parts. This means existing spares carrying those series numbers can replace the AGC-3/8-R without changing holders or re-rating the circuit.

Questions about this item

Does the AGC-3/8-R fuse come as a single piece or do I need to buy a fuse holder separately?

The AGC-3/8-R is a single cylindrical glass fuse; a compatible fuse block such as the 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB or S-8000 series must be purchased separately.

Should I choose this 0.375 A fuse or a higher-rated AGC model for my 125 V circuit?

Select the 0.375 A rating only if your circuit’s normal current is at or below 0.375 A; for higher continuous current you need a higher-rated AGC fuse with the same 1-1/4 in length and 1/4 in diameter.

What does the 10 kA at 125 V interrupt rating mean when the fuse is installed in my equipment?

It means the fuse can safely break a fault current up to 10 kA on a 125 V AC supply; at 250 V AC the interrupt capacity is 35 A, so the fuse must only be used where prospective short-circuit current stays within those limits.
