Meet the Bussmann 15A Time Delay Fuse, a reliable, slow-blow solution designed to protect electronic circuits without nuisance trips. This two-pack delivers consistent performance in low-voltage applications, combining industrial-grade reliability with practical carded packaging for quick stocking and easy inventory management.
-
Ampere rating: 15 A fast enough to protect circuits, yet time-delay (slow-blow) to handle brief inrush currents common in power supplies, transformers, and motor drives.
-
Voltage rating: 32 V, making it ideal for a wide range of electronics and auxiliary circuits in consumer, industrial, and automotive-style applications.
-
Construction: Glass tube with nickel-plated brass endcaps for sturdy electrical contact and robust durability in standard fuse holders.
-
Size: 1/4" diameter and 1-1/4" length, a familiar, widely compatible format that fits many standard fuse blocks and holders.
-
Packaging: Carded, 2-pack for convenient stocking and quick replacement when you’re repairing multiple units or building a kit.
-
Listings: UL Listed and CSA Listed, offering confidence in safety and compliance for professional and DIY projects alike.
-
Tamper protection: Non-tamper-proof design, suitable for standard enclosure configurations where standard protection is sufficient.
Why choose a time-delay fuse over a fast-acting alternative? In devices with motors, transformers, or capacitive loads, inrush currents can trigger a traditional fuse even when the circuit is operating normally. The time-delay characteristics of this fuse absorb brief surge events, then restore protection as soon as the inrush dissipates. That means fewer false trips and more reliable protection for your equipment.
Ideal use cases include:
- Power supplies and DC-DC converters where brief startup surges occur
- Motors, fans, and relay coils in small appliances or control panels
- Battery charging circuits and electronics projects requiring dependable, repeatable protection
- Repair work and BOMs for hobbyists, technicians, and OEM assembly lines
Practical tips for optimal results:
- Match the fuse rating to your circuit’s continuous operating current, ensuring the slow-blow behavior accommodates startup surges.
- Use in a compatible fuse holder that accepts 1/4" x 1-1/4" time-delay fuses to maintain proper contact and thermal performance.
- Store and handle fuses in a dry environment to preserve the integrity of the glass tube and endcaps.
With its proven Bussmann heritage, this 2-pack provides ready-to-use protection that’s easy to deploy in a variety of electronic applications. Whether you’re stocking a shop, outfitting a repair bench, or updating an OEM design, these 15A time-delay fuses offer dependable, industry-standard performance you can trust.
