Bussmann AGC Series Fast-Acting Fuse, 250VAC/32VDC
The Bussmann AGC Series delivers fast-acting fuse protection engineered for electronic circuits, control panels, and instrumentation systems. This series is built around a 250VAC/32VDC voltage rating (self-certified) with ferrule end connections, and is available in a range of amperage ratings from 1.2A through 20A so you can match the exact overcurrent protection your circuit requires. Every fuse in the AGC Series shares the same fast-acting response characteristics, 200 AIC interrupt rating at 250VAC, and compact glass-tube footprint, giving you dependable, consistent protection across the full lineup regardless of which amperage option you select. Bussmann designs the AGC Series specifically for electronic circuit applications where precise, repeatable overcurrent response matters as much as physical fit inside crowded enclosures.
Key Features
- Amperage Rating Options: Available in 1.2A, 2A, 3A, 5A, and 20A ratings, letting you select the precise overcurrent protection point for sensitive electronic circuits and components without oversizing or undersizing the fuse.
- Fast-Acting Response: Quick interruption capability protects connected equipment against short circuits and overloads, with a response time of 60 minutes maximum at 135% of rated current and 120 seconds maximum at 200% of rated current across the series.
- 250VAC/32VDC Voltage Rating: A self-certified voltage rating gives the AGC Series versatile compatibility for both AC and DC electronic circuit applications, so one fuse family can cover mixed-voltage equipment designs.
- 200 AIC Interrupt Rating: High fault current interruption capability at 250VAC (10 kAIC at 125VAC) ensures the fuse clears faults reliably instead of arcing or rupturing under demanding fault conditions.
- Ferrule End Connections: A ferrule end x ferrule end design (no axial leads) provides secure, low-resistance electrical contact in a standard fuse holder and keeps installation and replacement straightforward.
- Compact Design: A 1.25 IN length by 0.25 IN width and 0.25 IN height footprint allows the AGC Series to install in space-constrained electronic equipment, control panels, and instrumentation enclosures.
- Non-Indicating Fuse Body: Standard non-indicating construction keeps the fuse body simple and reliable for everyday electronic circuit protection duty where visual blown-fuse indication is not required.

Bussmann AGC-1-2/10 – Frequently Asked Questions
1) Will a Bussmann AGC fuse fit a standard 1/4 x 1-1/4 inch fuse holder?
Yes. The AGC glass fuse is the standard 1/4 inch diameter by 1-1/4 inch long ferrule body, listed at 1.25 IN length and .25 IN width and height, with ferrule end x ferrule end terminations and no axial leads. It drops into any clip-style or panel-mount holder built for that size.
2) Is a fast-acting AGC fuse the right choice for a circuit with motor or transformer inrush?
Probably not. The AGC is a fast-acting fuse built for electronic circuits, where you want the fuse to clear quickly on a fault rather than ride through a surge. Inductive loads that draw heavy startup current will nuisance-blow it unless you oversize, which defeats the protection. For inrush, use a time-delay (slow-blow) fuse of the same 1/4 x 1-1/4 size instead.
3) What amp ratings does the Bussmann AGC fast-acting fuse come in?
Five ratings are offered: 1.2A (AGC-1-2/10), 2A (AGC-2-R), 3A (AGC-3-R), 5A (AGC-5-R) and 20A (AGC-20-R). Everything else about the fuse, the fast-acting curve, the glass ferrule body and the voltage rating, stays the same across the range, so you only pick the amperage your circuit calls for.
4) How fast does the AGC fuse actually open on an overload?
On the published curve it opens within 60 minutes maximum at 135 percent of rated current and within 120 seconds maximum at 200 percent. That is the numbers to compare against your equipment's withstand time when you are sizing protection for instrumentation or a test bench supply.
5) What fault current can the AGC series interrupt?
200 amps interrupting at 250VAC, and 10 kAIC at 125VAC. For a low-energy electronic or instrumentation branch that is fine; on a circuit with high available fault current at 250V, spec a fuse with a higher AIC rating.
6) Do AGC fuses show when they are blown?
No. The AGC is non-indicating construction, so there is no pop-up pin or LED flag. You check it visually through the glass tube or with a meter. If your panel needs at-a-glance fault indication, choose an indicating fuse or a holder with a blown-fuse indicator.
7) Where are Bussmann AGC fuses typically used?
Electronic circuit protection is the design target: control panels, instrumentation, communication gear, test equipment and general industrial electronics. The compact glass tube suits crowded enclosures where board- or panel-mounted holders are tight.
