What Is a Short Protection Circuit?

A short protection circuit is an electrical circuit with a safety feature to address concerns about short circuits, where power moves through a circuit abnormally, often causing a current overload. Shorts, as they are known, can be dangerous and may also cause damage to equipment. Particularly for high energy systems, putting measures in place to respond quickly to shorts is very important, and often required under the electrical code.


There are two common methods of adding short protection to an electrical circuit, fuses and breakers. Fuses contain a thin strip of wire that melts in high temperatures associated with current overloads, turning the circuit off. Breakers operate mechanically, responding to current overloads by flipping to break the circuit. Both options have advantages and disadvantages; the key issue for consumers is that after a short, fuses need to be replaced, while breakers can be returned to their normal operating position.


The goal of a short protection circuit is to react as soon as abnormal flows of electricity are detected. This will prevent damage to the circuit and can reduce the risks of injuries. When a short develops, the circuit breaks, no longer allowing energy to move through it. The short protection circuit can also turn off the power supply. Until an electrician examines the circuit and determines the nature of the problem, it will remain off.
