Glass Fuse 3.15A 250V T5x20mm

Glass Fuse 3.15A 250V (T5x20mm)

The Glass Fuse 3.15A 250V (T5x20mm) is a vital safety component widely used in electronic and electrical circuits to protect against overcurrent and short-circuit conditions. This specific fuse is designed to handle currents up to 3.15 amps and voltages up to 250 volts AC, making it suitable for medium-power devices and general-purpose protection applications. Its time-delay (slow-blow) characteristic allows it to tolerate temporary current surges—such as those occurring when a device first powers on—without immediately blowing, which prevents nuisance interruptions.

Constructed in a 5x20mm glass body with metal end caps, this fuse allows for easy inspection to visually confirm if the fuse element has melted. The glass housing also provides excellent insulation and stability, while the compact size ensures compatibility with a wide range of PCB-mounted or in-line fuse holders. Its physical format conforms to international safety and dimensional standards, making it interchangeable across many brands and circuit designs.

The slow-blow feature of this fuse makes it ideal for applications involving inductive loads such as motors, transformers, or power supplies, where inrush currents are common. It ensures the circuit is only interrupted when a sustained overcurrent occurs, thus providing both protection and operational reliability.

Typical applications for this fuse include home appliances, battery chargers, power adapters, audio systems, LED drivers, and industrial control equipment. It is widely preferred in situations where both current protection and tolerance to brief surges are necessary.

In summary, the Glass Fuse 3.15A 250V (T5x20mm) offers a dependable and cost-effective solution for circuit protection. Its standard size, slow-blow behavior, and visual clarity make it a popular choice for engineers and technicians looking to safeguard electronic devices from overcurrent damage while ensuring stable performance.
