3939

Fuseholders are components that are used to secure fuse elements into electrical systems. They act as a connector and provide a secure connection between the fuse and the electrical system, allowing the electrical current to be carried safely to where it is needed while protecting against overloads.

A 3939 fuseholder is a plastic enclosed, screw-type 19mm fuseholder. It is designed for fuses sized 20mm × 5mm (B-C type). The fuseholder is made with a two-part molding process with an outer molding for mechanical protection and an inner molding for insulation. It is also designed with a heater plate to help ensure the contacts remain securely connected.

A 3939 fuseholder is a popular choice for modern equipment thanks to its insulation qualities and its ability to securely hold the fuse in place. The specific design of the holder is also suited to the size of the 19mm fuse making it a great choice for any application where a 19mm fuse is required.

The 3939 fuseholder is typically used in automotive, electronic, and electrical applications. For example, it is commonly used in the automotive industry for the wiring of lighting, meters, and indicators. It is also used in the electronics industry for circuit boards and power supplies. And in the electrical industry for wiring, control panels, and low-voltage systems.

The working principle behind a 3939 fuseholder is pretty simple. The holder has two screws on the sides, one to secure the fuse and one to secure the lead wires. When the fuse is placed into the holder, it creates a connection between the two screws. This connection can then be used to carry the electrical current to where it is needed, while the fuse itself acts as a safety mechanism to protect against overloads.

All in all, the 3939 fuseholder is an effective and reliable solution for any application requiring the use of a 19mm fuse. The enclosure provides protection against dust, dirt and moisture, while the screws and heater plate ensure a secure connection. The holder also keeps the fuse securely in place, ensuring the electrical current is safely transported to where it is needed.
