A power entry module (PEM) is an electromechanical component used in electrical appliances, integrating the appliance inlet with other components such as: a switch, possibly including integrated or remote bowden cable actuation; a circuit breaker, possibly including overload, overcurrent, or undercurrent protection, as well as remote triggering; an appliance fuse holder; a voltage selector; an electromagnetic interference line filter; an appliance outlet.Advantages of a power entry module over individual components: compact dimensions; unitized, standardized product with pre-assembled individual components; efficient mounting; alternative designs with similar dimensions may be substituted without major re-engineering; protected, pre-wired, tested, and certified power components.Power entry modules are used to save labor in manufacturing electrical and electronic equipment powered by an external source, such as the AC powerline.
