Power supplies often have protection from short circuit or overload that could damage the supply or cause a fire. Fuses and circuit breakers are two commonly used mechanisms for overload protection. Overload protection can be automatically enabled in response to high pressure or high temperature situations. Circuit breakers may be manually activated to interrupt the flow of electricity for the purpose of planned equipment maintenance or serviceable repair.
A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as to make contacts, break contacts or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal or where several circuits must be controlled by one signal.
