Fuse

Model fuse that protects against excessive current

Library

Passive Devices

Description

The Fuse block breaks the circuit in which it is connected. It does so when the current through the device exceeds the rated current at which the fuse is designed to blow and continues to exceed it for a specified amount of time.

Dialog Box and Parameters

Rated current

The current value at which the fuse blows when exceeded for a specified amount of time. The default value is 1 A.

Time to fuse

The time for which the current must exceed the rated current for the fuse to blow. The default value is 0 s.

Fuse resistance R

The fuse resistance. The parameter value must be greater than zero. The default value is 0.01 Ω.

Open-circuit conductance G

The open-circuit fuse conductance when the fuse has blown. The parameter value must be greater than zero. The default value is 1e-08 1/Ω.

Ports

The block has the following ports:

+

Positive electrical port

-

Negative electrical port
