Bussmann BP/S-15 15 Amp Type S Time Delay Plug Fuse 2 Pack 125V UL

Description

Product Overview

The Bussmann BP/S-15 is a 15‑ampere, Type S, time‑delay plug fuse designed for demanding electrical environments where reliability and safety are paramount. Engineered with a dual‑element construction, this fuse combines a fast‑acting element with a secondary, slower‑acting element to provide a controlled response to inrush currents, making it especially suitable for motor‑driven equipment that experiences frequent start‑stop cycles. The fuse is UL listed, ensuring compliance with rigorous safety standards, and operates at a nominal voltage of 125 V. Its robust metal housing offers superior durability, resistance to mechanical shock, and excellent heat dissipation, extending the service life of the fuse even under harsh conditions. The threaded base is compatible with standard SA adapters, allowing for straightforward installation in a wide range of panels, enclosures, and equipment housings. Each package contains two fuses, providing a convenient spare or enabling simultaneous protection of duplicate circuits.

Usage

This plug fuse is ideally suited for protecting critical motor circuits in industrial machinery, HVAC systems, compressors, and other equipment that experiences high inrush currents at start‑up. The time‑delay characteristic helps prevent nuisance tripping while still offering rapid protection against overloads and short circuits. Because of its dual‑element design, the BP/S-15 can also be used in commercial lighting fixtures, power distribution panels, and any application where a balance between immediate fault clearance and tolerance for temporary overloads is required. The 2‑pack configuration makes it an excellent choice for maintenance technicians who need to replace fuses quickly without waiting for additional inventory, reducing downtime and keeping operations running smoothly. Its compact dimensions (6 × 3 × 2 inches) allow for easy placement in tight spaces, and the metal construction ensures long‑term reliability even in environments with temperature fluctuations or exposure to dust and debris.

FAQ

What does a time‑delay fuse do?

A time‑delay (or slow‑blow) fuse allows a temporary surge of current, such as the inrush current when a motor starts, to pass without opening the circuit. It then trips if the overload persists, protecting equipment from damage while avoiding unnecessary interruptions.

Can I replace a single‑element fuse with the BP/S-15?

Yes, the BP/S-15 is designed to be a drop‑in replacement for standard Type S plug fuses, provided the voltage and current ratings match the original specifications. Always verify the circuit requirements before substitution.

Is the BP/S-15 suitable for residential use?

While the fuse meets UL standards and can be used in residential settings, it is primarily intended for industrial and commercial applications where motor loads and frequent cycling are common. For typical household circuits, a standard residential fuse may be more appropriate.

How do I know when the fuse has failed?

A failed fuse will show a visible break in the metal element or a darkened, melted appearance. In a time‑delay fuse, the secondary element may appear intact while the primary element has opened. Replace the fuse with an identical BP/S-15 model to restore protection.

What warranty does Bussmann provide for this fuse?

The BP/S-15 comes with a standard manufacturer warranty covering defects in material and workmanship. For detailed warranty terms, consult the product documentation or contact our customer support team.

Overall, the Bussmann BP/S-15 15 A Type S time‑delay plug fuse delivers a blend of safety, durability, and convenience that makes it a top choice for professionals seeking reliable circuit protection. Whether you are outfitting a new installation or maintaining an existing system, this fuse provides the confidence that your equipment will stay protected against overloads and short circuits while minimizing unnecessary downtime.
