Abstract
An improved remote actuator for use with a circuit breaker includes a handle assembly that can be disposed at the exterior of a cabinet and an actuation assembly that is operatively connected with the handle assembly and with the circuit breaker. The remote actuator includes a spring that is connected with a transfer link of the handle assembly and that biases a handle of the handle assembly to either an ON position or an OFF position. The remote actuator includes a fulcrum member on a bracket of the actuation assembly that at least partially overcomes the bias of the spring to facilitate assembly of the remote actuator.
Claims15
A remote actuator, the remote actuator being structured to remotely operate a circuit breaker, the remote actuator comprising:
- a handle assembly;
- the handle assembly including a handle;
- the handle assembly including a transfer link;
- the transfer link including a link attachment portion;
- the handle assembly including a spring;
- an actuation assembly;
- the actuation assembly including a bracket;
- the actuation assembly including a transmission assembly;
- the transmission assembly including a transmission attachment portion;
- the transmission assembly being structured to be operatively connected with the circuit breaker;
- the handle being operatively connected with the transfer link;
- the spring biasing the link attachment portion generally away from the transmission attachment portion;
- a fulcrum member;
- the fulcrum member being disposed on one of the handle assembly and the bracket;
- and
- the transfer link being engageable with the fulcrum member to at least partially overcome the bias of the spring and to facilitate operative connection of the transfer link with the transmission assembly by moving the link attachment portion from a first position at a first distance from the transmission attachment portion to a second position at a second distance from the transmission attachment portion, the second distance being less than the first distance.
A power distribution assembly comprising:
- a cabinet;
- the cabinet including an interior;
- the cabinet including an exterior;
- a circuit breaker;
- the circuit breaker being disposed within the interior of the cabinet;
- a remote actuator;
- the remote actuator including a handle assembly;
- the remote actuator including an actuation assembly;
- the handle assembly including a handle;
- the handle assembly including a transfer link;
- the transfer link including a link attachment portion;
- the handle being operatively connected with the transfer link;
- the handle assembly including a spring;
- the actuation assembly including a bracket;
- the actuation assembly including a transmission assembly;
- the transmission assembly including a transmission attachment portion;
- the transmission assembly being operatively connected with the circuit breaker;
- the spring biasing the link attachment portion generally away from the transmission attachment portion;
- a fulcrum member;
- the fulcrum member being disposed on one of the handle assembly and the bracket;
- and
- the transfer link being engageable with the fulcrum member to at least partially overcome the bias of the spring and to facilitate operative connection of the transfer link with the transmission assembly by moving the link attachment portion from a first position at a first distance from the transmission attachment portion to a second position at a second distance from the transmission attachment portion, the second distance being less than the first distance.
A method of assembling a remote actuator comprising:
- providing a handle assembly including a handle, a transfer link, and a spring, the transfer link being operatively connected with the handle;
- providing an actuation assembly including a bracket and a transmission assembly;
- biasing the transfer link away from the transmission assembly with the spring;
- providing a fulcrum member disposed on one of the handle assembly and the bracket;
- engaging the transfer link with the fulcrum member;
- at least partially overcoming the bias of the spring;
- and
- attaching the transfer link to the transmission assembly.
