Motor protection switches
Motor protection switches are primary circuit electromechanical protective devices. They are primarily used as manual motor switches (on/off) and for fuseless protection against short circuits, overloads, and phase failures. Fuseless protection is a cost-effective choice and requires minimal installation space. Additionally, it ensures rapid response in short-circuit situations by shutting down the motor within milliseconds. Motor starters are typically specified together with contactors.
