170M4743 is a type of specialty fuse. It has a wide range of application fields and working principle. The fuse has a high breaking capacity at lower melting energy, which makes it a viable option for protecting electrical circuits from overload, short circuit, and other related damages.

The typical application field of this fuse is, but not limited to, switching equipment in electromagnetic contactor, high speed fuse, fast-acting fuse cartridge, molding wall base, power circuit breaker, power fuses, circuit breakers, and terminal blocks. It can also be used to protect other sensitive equipments, such as motor starters, high power transformers, dropping resistors, and electric heaters.

The salient features of the 170M4743 speciality fuse include current limitation, fast response, high interrupting capacity, and low let-through energy. It provides protection from high current situations such as arcs, short-circuits, as well as other related issues. The protective characteristics of the fuse are in compliance with national standards, such as ANSI, IEC, and UL.

The working principle of the 170M4743 speciality fuse is simple. It involves two key components - a fuse wire and a fuse body. The fuse wire is made of copper or nickel-chrome alloy. It conducts electrical current, which causes it to heat up, and when it reaches a certain temperature, it melts. This breaks the connection to the circuit, thus protecting it from any further damage.

The fuse body is made of plastic or hard rubber material. It serves as an enclosure to hold the fuse wire and protect it from environmental influences. It also facilitates the connection of the external conductor to the circuit. When the fuse wire melts, the plastic or rubber insulation will also melt away, leaving the wire exposed and thereby disconnecting it from the circuit.

The 170M4743 specialty fuse is an invaluable tool for protecting electrical equipment from overload and short circuit. Its protective characteristics are in accordance with national standards, and its working principle is simple and reliable. With its high breaking capacity at low melting energy, this fuse is a great solution for safeguarding your electrical circuits.
