Fuseholders

CH143D application field and working principle

The CH143D is a linear fuseholder designed to provide reliable protection for the most demanding applications. It features an inline fuse design that provides superior current carrying capability, as well as easy installation and removal of fuse cartridges. The CH143D is ideally suited for a wide range of applications, including but not limited to, power distribution systems, electronic products, circuit protection systems, and other applications where over-current or short-circuit protection is desired.

The CH143D is designed for use with Class T, RK1, and CK fuses. The fuseholder is designed to easily snap onto a DIN rail and accepts standard 6.35 mm x 22.22 mm fuses. It features a two-level terminal block which protects the fuse from short circuits and other over current situations. The block is rated up to 20A and is rated for use with up to 750VAC.

The CH143D is constructed of thermoplastic material which is resistant to flame, corrosion, and adverse environmental conditions. The thermoplastic body protects the interior components, and allows the fuse cartridge to be removed without disconnecting any wires. The fuseholder also features an integrated shock-proof cover that helps protect the user from accidental contact with the terminals.

In operation, the CH143D fuseholder operates via a two-level terminal block. The first level is a female contact which is used to connect the power in and the power out connections. This connection is made via a standard 6.35 mm x 22.22 mm fuse. The second level consists of a male contact which is used to connect the ground connection. This ground connection is also made via a standard 6.35 mm x 22.22 mm fuse.

The CH143D is an ideal solution for a wide range of applications where over-current or short-circuit protection is desired. Its easy installation and removal of fuse cartridges make it very convenient to use. Additionally, its thermoplastic construction ensures that it is highly resistant to flame, corrosion, and adverse environmental conditions. Finally, its two-level terminal block makes it very easy to connect power and ground connections to the fuseholder.
