170M6809D

The 170M6809D is an electric specialty fuse used in a variety of applications. It is a multi-voltage shutdown device, and applications include fire alarm systems, marine switches, medical equipment displays, register terminals, and telecommunication systems. It is made up of an external contact element, the contact element is a screw down type, and its internal construction consists of a fuse element, copper terminal, and an insulating handle.

The 170M6809D is designed to protect circuits from overloads and short-circuits. It is UL and CSA listed, and its voltage ratings range from 110V to 220V. The fuse has a breaking capacity of 1kA at 120VAC, a current rating of 17A at 250VAC, and a voltage rating of up to 500VAC. The fuse is Impact Modified Resistor rated to 8kA at 500VAC.

The working principle of the 170M6809D is that when an overload or short circuit occurs, the current through the fuse element spikes. This causes the fuse element to overheat and soften, eventually breaking in two. This interrupts the circuit, and current stops flowing. The fuse element is designed to melt before the wiring or other parts of the circuit overheat.

The 170M6809D is a specialized electric fuse used for a variety of applications. It is UL and CSA listed and resistant to shocks up to 8kA at 500VAC. Its fuse element is designed to break before the wiring of the circuit can be damaged by an overload or short circuit. The contact element is screw down type, and the voltage ratings range from 110V to 220V.
