ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates remote operating devices, and more particularly to remote operating devices for circuit breaker handles.
TECHNICAL FIELD
Remote operating devices allow movement from an “ON” or an “OFF” position of circuit protection devices by remote signaling. With typical configurations of operating mechanisms within circuit protection devices, this requires a high-speed and high-torque force applied to a handle of to reposition springs within the operating mechanism. An electric motor is commonly used to actuates a mechanism such as a ball screw and nut assembly. The mechanism transfers motion to turn a handle of the circuit protection device to the “ON” or “OFF” position. The motor operating device is signaled by a remote programming device, generally by a wired signal.
While existing remote operating devices are suitable for their intended purposes, there still remains in need for improvements, particularly related to energy requirements, speed, cost, and reliability.
SUMMARY OF THE INVENTION
An electrically actuated device generates a force required to turn a circuit protection device from the “ON” or “OFF” position. This device is a replacement of electric motors used to provide the force to move a circuit protection device handle.
The device includes a body having a receiving area to receive and engage a portion of the circuit breaker handle. The body is fixedly secured to a shaft for movement between a first position and a second position. Movement is effectuated by forces in opposite directions transmitted to the shaft provided from a pair of coils.
The above discussed and other features and advantages of the present invention will be appreciated and understood by those skilled in the art from the following detailed description and drawings.
