170M3271

170M3271 is a special type of fuse whose type is ‘medium length’, which is designed for complying with secure and fast disconnection of the supply line that is used to protect circuit components and building wiring. This type of fuse offers ultimate protection when connecting or disconnecting from the electrical grid, making it a perfect choice for an array of applications.

Application Fields and Working Principle

The 170M3271 is suited for the following applications: Cables or wires with a maximum rated voltage of DC 420V and AC 600V, a rated connection current of 0.1A to 600A, and a rated short-circuit breaking capacity of 6kA. With its long and slender design, this fuse can be widely used in small-capacity circuits, such as IGBTs, inverters, and AC contactors. In addition, the fuse functions in ‘timeout’ mode and ‘remote-controlled with remote monitoring’ mode, which makes it applicable for various automation equipment.

Because the 170M327 fuse features a fast fuse body and contact, it can be applied to a wide variety of electrical circuits, providing efficient protection. The reliability and durability of the fuse is guaranteed by the solid-material insulation technology and anti-vibration performance. The fuse has the capability of not fusing automatically at ambient temperatures ranging from -25��C to 80��C, and it also features voltage overload protection, thermal overload protection, short circuit protection, over voltage protection, and under voltage protection.

The working principle of the 170M3271 is quite simple. It has two contacts that are connected together by a fuse link made of a special material. When the current running through the fuse link reaches a certain threshold, the heat generated by the current causes the material to melt and break the connection between the two contacts, thus shutting down the circuit and protecting it from further damage.
