Bussmann TL-30PK4 30A TL Edison Plug Time Delay Fuse 4 Pack

Description

Product Overview

The Bussmann TL-30PK4 is a 30‑ampere, TL‑type Edison plug fuse designed specifically for applications that require a reliable time‑delay characteristic. Engineered with a robust ceramic body and a high‑quality metal element, this fuse offers superior arc‑quenching performance, ensuring that it can safely interrupt fault currents without compromising the surrounding wiring. Its time‑delay (also known as slow‑blow) design allows temporary inrush currents—common when electric motors start—to pass without opening, while still providing protection against sustained overloads. The fuse is rated for 125 volts and conforms to UL standards, making it suitable for a wide range of residential and light‑duty commercial installations.

Dimensions of the TL‑30PK4 measure 28.44 × 2.25 × 1.25 inches and it weighs just 4.16 ounces, allowing for easy handling and installation in standard plug fuse panels. The product is packaged in a convenient 4‑count pack, ensuring that electricians and DIY enthusiasts have immediate access to spare units for quick replacements. Since its introduction in September 2013, the TL‑30PK4 has earned a solid reputation, reflected in a 4.6‑star rating from over 600 customer reviews and a strong sales rank within the plug fuse category.

Usage

This fuse excels in environments where motor loads are prevalent, such as HVAC systems, small compressors, pumps, and other appliances that experience high starting currents. Home workshop stations, garage door openers, and residential lighting circuits that incorporate motorized components also benefit from the TL‑30PK4’s ability to tolerate brief overloads while still protecting the circuit from longer‑duration faults. Its compact form factor allows it to be installed in traditional plug fuse holders found in many older residential panels, as well as in newer load centers that support TL‑type fuses.

When selecting a fuse for a specific application, consider the continuous load current of the motor and the expected inrush current at start‑up. The TL‑30PK4’s 30 A rating provides a close match for many 2‑ to 3‑horsepower motors, delivering a balance between protection and performance. Install the fuse by first turning off power to the circuit, removing any existing fuse, and inserting the TL‑30PK4 into the appropriate slot, ensuring a secure fit. After installation, verify that the circuit operates correctly and that the fuse does not heat excessively during normal operation.

FAQ

What does a time‑delay (slow‑blow) fuse do?

A time‑delay fuse allows short‑duration, high‑current spikes—such as those caused by motor start‑up—to pass without opening, while still protecting the circuit from sustained overloads that could cause damage.

Can I replace a standard plug fuse with the TL‑30PK4?

Yes. The TL‑30PK4 is a TL‑type Edison plug fuse that fits the same slots as standard plug fuses, making it a direct replacement in most residential and light‑duty panels.

Is the TL‑30PK4 suitable for outdoor installations?

While the fuse itself is sealed and can tolerate typical indoor environments, it should be installed in a protected panel or enclosure that shields it from direct exposure to moisture and extreme temperatures.

How many fuses are included in the package?

The package contains four individual TL‑30PK4 fuses, providing immediate spares for quick replacements or multiple circuit installations.

What warranty does Bussmann offer on this fuse?

Bussmann provides a limited warranty that covers manufacturing defects for a specified period. For detailed warranty terms, contact Bussmann customer service or refer to the product documentation.
