Abstract
A system comprising a magnetic actuator, a current transformer and operational electronics in a dual-coil circuit breaker. The system includes an inline implementation of the primary and secondary coils to maintain a narrow width suitable for retrofitting in currently designed industrial rack mounted enclosures. The system further comprises network connectivity allowing interrogation of the components for operational data associated with the component.
Claims20
A circuit breaker system, the system comprising:
- a primary coil adapted to provide current based overload protection;
- a secondary coil adapted to provide voltage based overload protection, wherein the secondary coil is positioned inline with the primary coil;
- and
- a processor, communicatively coupled to a memory, configured to execute or facilitate execution of computer-executable components stored on the memory, the computer-executable components comprising:
- a control system interface component adapted to communicate operational data with an industrial automation device, wherein the operational data includes data indicative of a load exerted on a plunger deflector spring.
A non-transitory computer readable storage medium comprising computer-executable instructions that, in response to execution, cause an industrial control system comprising a processor, to perform operations, comprising:
- communicating, with an industrial automation device, operational data associated with a circuit breaker system, wherein the circuit breaker system includes a first coil, wrapped around a plunger, that provides current-based overload protection and a second coil that provides voltage-based overload protection, the second coil is implemented inline with the first coil;
- and
- determining measurement data based on measuring a load exerted on a plunger deflector spring, wherein the communicating includes facilitating a transmission of the measurement data to the industrial automation device.
A method, comprising:
- measuring current through a primary coil that is wrapped around a plunger of a circuit breaker system;
- measuring voltage across a secondary coil that is inline with the primary coil;
- and
- facilitating, by a system including a processor, a communication of operational data with an industrial automation device, wherein the facilitating includes facilitating a transmission of data indicative of a load exerted on a plunger deflector spring.
