170M4564 is a type of specialty fuse electrical devices used in circuit protection applications. It is a small cylindrical device with two ends, one end having a lug to which a lead wires are soldered, and the other end having a metal contact which connects to an auxiliary contactor. The fuse is designed to provide protection against current overload in the circuit it is used in, and the design also ensures that the metal contacts do not overheat and cause tripped circuits. The fuse has a current rating of 45/64A and is UL recognized.

The 170M4564 specialty fuse is typically used in electrical control applications such as motor starters, starter controls, switches, relays, contactors, transformer starters and other protection and control devices. It is UL recognized, and meets UL and CSA standards for performance and safety. The fuse is constructed with a polyester and glass-fiber composite casing which is flame retardant and is designed to provide excellent short-circuit protection by melting the internal element quickly when excessive current overloads occur. The fuse also has a maximum standard operating current of 35/64A, and an instantaneous operating current of 45/64A which can be reset as soon as the over-current is removed to bring the circuit back into normal operating condition.

The working principle of the 170M4564 specialty fuse is based on the phenomenon of excessive current causing the fusible link to melt, thereby breaking the circuit it is connected in. The fusible link is made of a metal alloy that has a designed melting point just above the rating of the fuse. When excessive current flows through the circuit, the fuse will heat up, causing the link to melt. This effectively breaks the circuit, thus preventing any further damage to the circuit. The fusible link resets itself when the over-current is removed, thereby allowing the circuit to return to its normal operating condition.

The 170M4564 specialty fuse is invaluable in preventing damage to circuits due to excessive current overloads. This type of fuse is both cost effective and highly reliable, and is used in a wide range of applications such as automotive, industrial and aerospace installations. Its UL recognition ensures that it meets all safety and performance standards and is suitable for use in applications such as motor starters, control panels and other circuit protection applications.
