Eaton AGU-40 Fuse - 40A Fast-Acting, 32V Ferrule End
Part Number: AGU-40
Quick Summary
The Eaton AGU-40 fuse provides fast-acting overcurrent protection for appliance and consumer electronics circuits. Engineers often struggle with nuisance trips, undersized protection, or unclear indicator status in compact fuse packages. Typical certifications relevant to this family include CE marking for European safety, UL recognition for North American use, and RoHS compliance. Using this fast-acting fuse in the right place improves equipment reliability, reduces downtime, and lowers spare-part stocking costs over the lifecycle of electronic systems. Its ferrule-end design, nickel-plated endcaps, and compact 1.5 inch length support simple, quick installation in panel-mount and harnessed configurations. This aligns with lean manufacturing goals by enabling predictable lead times and standardized spares.

AGU-40 is a fast-acting fuse rated for 40 A at 32 V, designed to protect compact appliance and consumer-electronics circuits without excessive response time delays. Its fast-acting characteristic translates into precise fault clearing, reducing arc energy and material damage in confined spaces where heat buildup is a critical concern. The 1.5 inch length and ferrule-end to ferrule-end connection simplify drop-in replacement in existing Bussmann AGU arrays, accelerating service and minimizing equipment downtime. Nickel-plated brass endcaps provide durable electrical contact and corrosion resistance in vibration-prone or humid environments, improving uptime in industrial, laboratory, and home-appliance settings. Coupled with the standard ferrule ends, this makes installation straightforward in both panel-mounted and wired harness configurations. The construction also supports reliable memory retention during field replacement, reducing rework and callouts. The AGU-40 uses a non-indicating fuse indicator, reducing false positives in busy panels and lowering diagnostic time. Silver-plated fuse caps further enhance contact reliability, particularly in high-cycle applications common in consumer electronics. The combination of non-indicating status with durable caps helps maintain clean panel aesthetics while preserving safety margins. With standard packaging and a conservative 0.25 lb weight, this fuse is easy to stock and replace across multiple lines. Its compact dimensions (1.5 in length, 0.41 in width, 0.41 in height) fit narrow enclosures and busy control panels without crowding adjacent components. The packaging supports quick pull-and-replace maintenance programs and minimal spare-part variance. Voltage rating of 32 V positions AGU-40 well for DC control circuits and low-voltage appliance protection, while the 40 A rating covers typical load profiles in consumer electronics. This device integrates seamlessly with Bussmann AGU arrays and ferrule-end harnesses, enabling fast field upgrades and uniform protective strategies. In practice, engineers gain predictable protection behavior, lower total cost of ownership, and improved mean time between failures when deploying these fuses in the right locations.

FAQs
AGU-40 uses ferrule-end x ferrule-end connections and nickel-plated brass endcaps, offering a secure mechanical fit and excellent contact reliability in panel assemblies and wire harnesses. This compatibility reduces the need for adapters and simplifies replacement in existing Bussmann AGU arrays, supporting rapid service in production lines and service centers.
Rated 40 A at 32 V and designed to be fast-acting, AGU-40 clears short circuits quickly to protect motors, power supplies, and electronics without delaying startup for healthy loads. This reduces arc energy, minimizes component damage, and extends equipment life in consumer appliances and small home electronics.
Yes, AGU-40's 32 V DC rating fits standard control circuits and low-voltage electronics. It should not be used where higher mains voltages apply, and ensure correct amperage matching to the load to avoid nuisance trips or underprotection.
Use ferrule-end connections with compatible holders or panels, confirm the load current stays within 40 A, and avoid bending leads or stacking fuses that degrade contact reliability. Maintain stocked AGU-40 units within a Bussmann AGU family to minimize downtime during replacements.
By delivering predictable protection, reducing unexpected outages, and enabling standardized spares across lines, AGU-40 lowers maintenance costs and improves mean time between failures. The compact form factor also simplifies design-in and reduces assembly time in consumer electronics and appliance assemblies.
