WebIn the case of the relatively low current fuses (up to 5 A), the fuse-element resembles a wire, whereas for higher rated currents has a strip shape. Designing the shape of the time-current characteristic for the fuse-links with wire is usually reduced to selecting the cross section of the fuse-element therefore their characteristics in the WebIts characteristics are: (i) It has a low melting point (m.p.) of about 200°C and is usually made from an alloy of 50% tin and 50% lead. (ii) It has a high resistance so that its temperature rises rapidly and soon exceeds its m.p. and thus breaks it, when current passing through it exceeds the permissible limits.

State Two Characteristics of a Fuse Wire. - Physics

WebApr 23, 2024 · A fuse is a simple and highly effective way to protect a device from dangerous levels of current: Current flowing through a conductor’s nonzero resistance … WebTo a fuse or circuit breaker, ground fault current is sensed just as any other current. If the ground fault current is high enough, the fuse or circuit breaker responds before the ground fault relay (this depends on the ground fault relay setting, overcurrent device characteristics, speed of response of the roman company hair loss

WebDec 6, 2016 · The characters of a fuse wire are as follows: a. It should have a high resistance. b. The melting point of a fuse wire is slightly less than the connecting wires. WebJan 5, 2024 · There are some of the important characteristics of the fuses in the electrical and electronic system which are as follows:- Current Rating: The continuously conducting maximum amount of current holds the fuse without melting it is termed as current ratings. It is the current carrying capacity, which is measured in Amperes. roman commander of 100 men
