Protect sensitive electronics with precision using the Jandorf AGC 4A Fast Acting Fuse — a 4-pack of 4-amp, 250-volt fuses designed for quick interruption of fault currents while staying reliable in everyday use. Built for electronic circuits, these AGC fuses combine compact form with dependable performance to safeguard power supplies, control boards, and other delicate components.
Key features you can rely on include a glass tube construction with plated brass endcaps for robust contact and durable operation in varying environments. Each fuse measures 1/4" in diameter and 1-1/4" in length, a standard size that fits a wide range of holders and panel configurations. With UL Listed and CSA Listed safety certifications, these fuses meet essential electrical standards for both DIY projects and professional installations. The packaging is carded, keeping the four fuses neatly organized and ready for fast replacements in the field or on the bench.

Use cases and best practices
Ideal for protecting power supplies, small electronics projects, and control circuits where a 4-amp fast-acting fuse is appropriate. Use in devices where fault currents are predictable and exceed normal operating loads, so the fuse clears quickly without allowing damage to upstream circuitry.
Practical tips to maximize performance:
- Match the fuse rating to the circuit’s maximum fault current. When in doubt, consult the device manual or a technician before replacement.
- Replace like-for-like after a trip—avoid altering the rating unless you fully understand the circuit’s fault dynamics.
- Handle with care and store in the carded packaging to prevent damage to the glass tube.
- Keep a spare set on hand for rapid field service or repair work, especially in electronics benches and service kits.
Whether you’re stocking a repair bench, assembling a compact power supply, or maintaining electronics inventory, the Jandorf AGC 4A Fast Acting Fuse 4 Pack delivers precise protection where you need it most—fast response, reliable construction, and standard compliance all in a compact, ready-to-use set.
