Bussmann SL-15 15 Amp Time Delay Plug Fuse, 125V UL Listed

Description

Product Overview

The Bussmann SL-15 15 Amp Time Delay Plug Fuse is engineered to provide dependable protection for a wide range of electrical applications. Constructed with a high‑quality copper alloy core and a robust polymer housing, this fuse offers excellent conductivity while resisting corrosion and mechanical stress. The time‑delay characteristic allows brief inrush currents, such as those from motor start‑ups, to pass without nuisance tripping, while still safeguarding downstream equipment from sustained overloads.

Designed to meet UL standards, the SL-15 is UL‑listed for 125 V operation, ensuring compliance with rigorous safety and performance criteria. Its loaded link rejection base features a spring‑loaded mechanism that securely locks the fuse in place, preventing accidental removal or misalignment during installation or maintenance. The compact dimensions—2.4 × 2.32 × 1.34 inches—make it an ideal fit for standard plug fuse slots in panel boards, load centers, and breaker boxes.

Key specifications include a 15 Amp rating, a time‑delay (slow‑blow) response, and a maximum voltage rating of 125 V. The fuse is rated for a breaking capacity that exceeds typical residential and light commercial loads, providing an extra margin of safety in fault conditions. With a package weight of just 2.4 ounces, the SL-15 is easy to handle and install, reducing labor time and effort for electricians and DIY enthusiasts alike.

Usage

The SL-15 is suited for a variety of environments, from home renovation projects to commercial facility maintenance. It excels in applications where motor-driven equipment, such as HVAC compressors, pumps, and fans, require a fuse that can tolerate short‑duration surge currents without compromising long‑term protection. Install the fuse in any standard plug‑type fuse holder within a load center, ensuring the holder is rated for the same voltage and current specifications.

For residential installations, the SL-15 provides peace of mind in kitchen appliance circuits, lighting circuits, and general‑purpose outlets that may experience occasional overloads. In commercial settings, it is an excellent choice for office equipment, small machinery, and backup power systems where reliable fault interruption is critical. The fuse’s time‑delay feature helps avoid nuisance trips while still delivering rapid response to genuine overloads, making it a versatile component for both seasoned professionals and hobbyist electricians.

FAQ

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

A time‑delay fuse is designed to tolerate short‑duration overloads, such as the surge current that occurs when a motor starts. It will not trip immediately, allowing normal start‑up currents to flow, but will open the circuit if the overload persists, protecting equipment from damage.

Can I use the SL-15 in a 240 V system?

No. The SL-15 is rated for a maximum voltage of 125 V. For 240 V applications, you should select a fuse specifically rated for that voltage to ensure safe operation and compliance with electrical codes.

How do I install the loaded link rejection base correctly?

First, ensure the power is turned off at the breaker. Insert the fuse into the plug‑type holder, aligning the metal contacts. The spring‑loaded mechanism will automatically engage, locking the fuse in place. Verify that the fuse sits flush and the base clicks securely before restoring power.

What warranty does Bussmann offer on the SL-15 fuse?

Bussmann provides a limited one‑year warranty covering manufacturing defects. If the fuse fails due to a defect within this period, contact our support team for a replacement. The warranty does not cover damage caused by improper installation or misuse.

Is the SL-15 suitable for outdoor installations?

While the fuse itself is sealed against moisture, the holder and surrounding enclosure must be rated for outdoor use. Ensure the installation environment meets the required IP rating for protection against water and dust before using the SL-15 outdoors.
