Description
Product Overview
The Bussmann SL-15PK4 is a 15 amp time‑delay plug fuse engineered for residential and light‑duty motor applications. Housed in a durable blue plastic shell, this fuse meets both UL and CE certification standards, guaranteeing safety and reliability in demanding electrical environments. Its time‑delay characteristic allows it to tolerate the brief inrush currents typical of motor start‑up, while the built‑in rejection mechanism ensures that a higher‑amp fuse cannot be mistakenly installed, protecting the circuit from overload. The fuse is designed to mount through a hole and thread directly into SA adapters, providing a secure and straightforward installation process. With a compact 2 × 3 × 3‑inch footprint and a lightweight 2.39‑ounce design, the SL‑15PK4 fits neatly into standard fuse panels and load centers, delivering consistent performance without adding bulk.

Usage
Ideal for protecting residential motor circuits such as ceiling fans, small pumps, and HVAC components, the SL‑15PK4 excels in environments where occasional surge currents occur. Its 125 V rating aligns with typical North American household wiring, making it a seamless replacement for older fuses in existing panels. Electricians and DIY enthusiasts alike appreciate the clear blue color coding, which simplifies identification during maintenance or upgrades. The fuse’s rejection feature is particularly valuable in settings where multiple fuse sizes are stocked, as it prevents the accidental installation of a fuse with a higher current rating that could compromise wiring integrity. Whether you are retrofitting an older home, servicing a new construction, or maintaining commercial equipment, this fuse offers dependable protection against short circuits and overloads.

FAQ
What does a time‑delay fuse do?
A time‑delay (or slow‑blow) fuse allows brief, high‑current spikes—common when motors start—to pass without opening, then trips if the overload persists, protecting equipment from damage.
Can I replace this fuse with a higher amp rating?
No. The built‑in rejection mechanism prevents installing a fuse with a higher current rating, ensuring the circuit remains protected against overloads.
Is this fuse compatible with all SA adapters?
Yes, the SL‑15PK4 threads directly into standard SA adapters, making it suitable for a wide range of plug‑type fuse holders used in residential and light‑duty applications.
What warranty does Bussmann offer?
The fuse comes with a manufacturer warranty that covers defects in materials and workmanship, backed by Bussmann’s dedicated technical support team.
How do I identify the correct fuse size?
Look for the blue color coding and the model number SL‑15PK4 printed on the fuse. The 15 A rating and 125 V voltage rating are also marked on the label for quick verification.
