Bussmann TL-20PK4 20 Amp Time Delay Plug Fuse 4 Pack Orange

Description

Product Overview

The Bussmann TL-20PK4 is a 20‑amp time‑delay plug fuse designed for use in residential and light‑duty electrical applications where motor start currents can cause nuisance tripping. Constructed from high‑quality copper and housed in a bright orange, surface‑mount Edison‑base cartridge, this fuse meets UL standards for safety and reliability. Each unit measures approximately 1.16 in. × 1.375 in. and weighs just 2.89 oz., making it easy to handle and install. The pack includes four identical fuses, providing ample inventory for multiple circuits or future replacements.

Usage

These fuses are ideal for protecting circuits that feed electric motors, such as garage door openers, small workshop equipment, and HVAC blower motors. The built‑in time‑delay characteristic allows the fuse to tolerate the brief inrush current that motors draw when starting, while still providing rapid interruption for sustained overloads. Because the TL‑20PK4 is a surface‑mount type, it can be installed in standard plug‑type fuse holders without the need for additional wiring or modifications. Homeowners, electricians, and DIY enthusiasts will find the orange color helpful for quick visual identification during maintenance or troubleshooting.

In addition to motor‑driven loads, the TL‑20PK4 works well in lighting circuits, small appliance outlets, and any application where a 20‑amp protective device is required. Its UL listing assures compliance with North American safety codes, and the copper construction offers excellent conductivity and heat dissipation, extending the service life of the fuse even under demanding conditions.

FAQ

What does a time‑delay fuse do?

A time‑delay (or slow‑blow) fuse allows a brief surge of current—common when motors start—to pass without opening, then trips if the overload persists, protecting equipment from damage.

Can I use this fuse in outdoor applications?

Yes, the orange‑colored housing is resistant to UV light and mild moisture, making it suitable for sheltered outdoor panels, but it should not be exposed to direct rain or extreme weather.

Is the TL‑20PK4 compatible with all fuse holders?

The fuse uses a standard Edison‑base (plug) design, so it fits any compatible plug‑type fuse holder that accepts 20‑amp fuses. Always verify the holder’s rating before installation.

How many fuses are included in the package?

The product ships with four individual TL‑20PK4 fuses, providing enough units for multiple circuits or future replacements.

What warranty does Bussmann offer?

Bussmann provides a limited warranty covering manufacturing defects. For specific terms, refer to the warranty documentation included with the product or contact our support team.
