170M8557D

The 170M8557D is an advanced type of electrical fuse specifically designed for circuit protection. It is a three-pole, square body fuse with a current rating up to 500A AC and is UL Listed for 600A applications. It is also a dual-element fuse, which means it is composed of two separate electrical circuits. The design of this fuse makes it ideal for applications such as motors, electrical appliances and machines, lighting systems, and others.

The 170M8557D works by carrying current through the two elements when switch is the source of the current and break the circuit when the current exceeds the rated value. If the current is abnormally high within the system, the fuse will disconnect, thus protecting the system. The hot element of the fuse will melt when the current reaches its rated value, opening the circuit, while the cold element will react only when the current reaches a much higher level than the rated one.

One of the advantages of this fuse is that it can protect motors and electrical appliances from dangerously high levels of current. It is also relatively safe to use when compared to some other types of fuses since it can reduce the risk of an uncontrolled fire or explosion due to an overcurrent condition. Additionally, the 170M8557D can be used in applications where over-current protection is required and the environmental conditions are relatively high.

The 170M8557D is designed to perform in ambient temperature ranges from -50°C to +50°C, and with no time delay or cut-off time. It is tested in accordance with UL and CSA standards as well as other international requirements. It’s rated current is 200A to 500A AC and its interrupting rating are 200A at 600 VAC, 500A at 30 VDC. It has a UL94V-0 flame retardant housing and is available in 4 sizes from 1 to 4.5", and it meets UL 4248/4248-2.

The 170M8557D is an ideal fuse for use in a wide variety of applications, including motors, electrical appliances and machines, air conditioners, lighting systems, and many other electrical circuits. It is reliable, easy to use, and provides the necessary protection that is needed. Its compact size makes it easy to install and maintain in tight spaces.

To conclude, the 170M8557D is an advanced type of electrical fuse designed to provide effective circuit protection. It can be used in a wide variety of applications including motors, electrical appliances and machines, and many other electrical circuits. It is UL listed, UL 94V-0 flame retardant, and suitable for use in temperatures ranging between -50°C to +50°C. Moreover, it is easy to install and maintain in tight spaces.
