Combined function circuit protection and control device actuator

摘要

A combined function actuator comprising a secondary actuator which is physically located entirely within the physical space of a circuit protection and control device primary short circuit solenoid actuator. The secondary actuator combined function housing is a plunger to the primary actuator and also a magnetic isolator having contained within it the means for independent actuation of a voltage independent or a voltage dependant circuit protection and control device. The combined primary and secondary actuator when engaged with a suitable mechanism can be utilised to open and close the main contacts of a circuit protection and control device. A significant amount of space within a circuit protection and control device is made available by each combined actuator thus enabling additional functionality to be added to a circuit protection and control device without increasing the overall dimensions of the device.
