Fuse Cut Out Schematic Symbol

Its essential component is a metal wire or strip that melts when too much current flows through it thereby stopping or interrupting the current.

Fuse cut out schematic symbol. D input circuit breaker b fuse rating b type refer to disconnect schedule fused disconnect switch. A thermal fuse is a temperature sensitive switch. Generic symbol fuse fuse ieee ansi system low speed fuse protection resistor thermal fuse thermal cutoff fuse fuse iec system fuse high speed fuse protection resistor disconnector isolator switch circuit breaker unipolar circuit breaker three pole circuit breaker circuit breaker isolator fuse oil for high voltages fuse switch switch with built. Electrical plan symbols electrical one line symbols duplex receptacle a circuit designation b device type designation quadruplex receptacle.

For example here s the trunk fuses card for a 2008 535xi e61. The symbol for a thermal fuse used in any electrical circuit diagram. The symbols i m talking about are the ones used for the fuse assignment cards that are installed in the covers of the fuse box. Its essential component is a metal wire or strip that melts when too much current flows which interrupts the circuit in which it is connected.

In electronics and electrical engineering a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. An example circuit with a fuse is shown below. Fuses and electrical protection symbols. A rheostat is used to control the current flow with two contacts.

This is the standard and most common type of symbol found for fuses in schematic diagrams. In electrical distribution a fuse cutout or cut out fuse is a combination of a fuse and a switch used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. It operates on the temperature rather than the current unless the current is sufficient to increase the temperature above the threshold point. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt disconnecting the transformer from the line.

What i ve been able to do so far is look in owner s manuals and find symbols displayed next to certain function descriptions. A resistor is used to restrict the amount of current flow through a device. You can see the fuse in series with the lamp on the right. Disconnecting fuse single fuse cut out medium voltage disconnecting fuse double fuse cut out.

Fuses are devices containing a small piece of special wire that melts when the intensity of the current flowing through it for a certain period of time exceeds a set value thus protecting the rest of the electrical circuit overloads.
