Fuses

Fuses

Fuses provide simple overcurrent protection for electrical and robotics projects. They come in a glass tube style suitable for use with common fuse clips, and in resettable polymer formats that save you from a smoky surprise when faults occur. Non-resettable fuses offer a single‑use safeguard, while resettable types recover after cooling.

You’ll also find mounting options for securing fuses in enclosures or on a PCB through-hole or clip‑in arrangements. These parts protect power rails, motor drives, controllers, and sensor networks, enabling quick, replaceable protection that fits compact hardware and educational rigs. Attributes vary in form factor, mounting style, and protection characteristics.

Fuse 5mm 125VAC 5A

Code: SKU-000501

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 125VAC up to 5A. Fuses are pretty simple if more than 5A pass through the fuse the small filament inside the fuse heats up and breaks (like a light bulb burning out).

Fuse Clip 5mm

Code: SKU-000502

This is a 5mm PTH fuse clip intended to be used with our Glass Fuses. Note: These are sold in single units. If you intend to secure a fuse using these clips you'll need two clips. We recommend ordering two. Part #: 1A3399-10

Polymeric Resettable Fuse PTC - 6V, 500mA

Code: SKU-011164

This is a handy little device that can save your system from smoking. A resettable fuse is a resistor that has very unique properties. For this model, if your circuit tries to draw more than 500mA of current (if you have a bad short for instance) the PTC would 'trip' (by heating up).
