Definitions

  • An actuator is typically used in electrical protection devices as a means to break a circuit after a fault condition has been detected.
  • an actuator used in electrical protection devices are typically a relay or a solenoid both having some form of plunger or lever which travels a set distance to interface with a mechanism that determines the contact state.
