Bussmann TL-25PK4 25 Amp Time Delay Plug Fuse 4 Count Black

Description

Product Overview

The Bussmann TL-25PK4 is a premium 25 amp time delay plug fuse designed for demanding electrical applications where reliable overload protection is essential. Engineered with a robust copper construction, this fuse offers superior conductivity and heat dissipation, ensuring consistent performance even under continuous load conditions. The chassis‑mount design allows for secure installation within a variety of panel types, while the black finish provides a professional appearance that blends seamlessly with standard electrical components.

Each unit in the four‑count pack is rated for 125 volts, making it suitable for both residential and commercial circuits that operate within standard North American voltage ranges. The time delay characteristic of the TL‑25PK4 helps to prevent nuisance tripping caused by temporary inrush currents, such as those generated by motor start‑up or transformer energization, while still providing rapid interruption in the event of a genuine overload or short circuit. This balance of sensitivity and tolerance extends the lifespan of downstream equipment and reduces maintenance downtime.

Key specifications include a current rating of 25 amps, a voltage rating of 125 volts, and a compact form factor measuring 3.6 x 2.2 x 2.3 inches. The fuse’s Edison base (plug) configuration ensures compatibility with a wide range of existing panel boards and load centers, simplifying retrofits and upgrades. With a weight of just 2.4 ounces, the TL‑25PK4 is lightweight yet durable, offering a reliable solution for both new installations and replacement scenarios.

Usage

Designed for versatility, the Bussmann TL‑25PK4 time delay plug fuse can be employed in a multitude of settings. In residential environments, it is ideal for protecting lighting circuits, small appliance outlets, and HVAC equipment where occasional surge currents are common. Commercial applications benefit from the fuse’s ability to safeguard motor‑driven machinery, office equipment, and building automation systems, ensuring uninterrupted operation during peak demand periods.

Electricians and DIY enthusiasts alike will appreciate the ease of installation provided by the chassis‑mount style. The fuse can be securely seated into a compatible plug‑type holder, and the copper contacts guarantee a low‑resistance connection that minimizes voltage drop. For projects involving panel upgrades, the TL‑25PK4’s compact dimensions allow it to fit into tight spaces without compromising safety standards.

When selecting a fuse for a specific circuit, consider the load’s continuous current draw and the potential for temporary inrush currents. The 25 amp rating of the TL‑25PK4 offers a comfortable margin for circuits rated up to 20 amps, providing an extra layer of protection without sacrificing performance. Its time delay feature is particularly advantageous in circuits that power compressors, pumps, or variable‑frequency drives, where start‑up currents can exceed the nominal rating for brief intervals.

FAQ

What does a time delay fuse do?

A time delay fuse, also known as a slow‑blow fuse, allows brief surges of current—such as those caused by motor start‑up—to pass without opening the circuit, while still protecting against sustained overloads.

Can I replace a standard plug fuse with the TL‑25PK4?

Yes, the TL‑25PK4 uses a standard Edison (plug) base, making it a direct replacement for most existing plug‑type fuses in residential and commercial panels.

Is the TL‑25PK4 suitable for outdoor installations?

The fuse’s black coating provides corrosion resistance, but for outdoor applications it should be installed in a weather‑protected enclosure to ensure optimal longevity.

How many fuses are included in the package?

The product is sold as a four‑count pack, offering four individual 25 Amp time delay plug fuses for multiple circuit protection needs.

What warranty does Bussmann offer on this fuse?

Bussmann provides a limited warranty that covers manufacturing defects, backed by responsive technical support to assist with any installation or performance questions.
