Circuit breaker having breaker information module and method of use
View Patent ↗A circuit breaker is described herein. In one aspect, the circuit breaker includes a communication module, a non-transitory memory device, and a memory controller. The communication module is configured to receive protection settings and breaker information from a trip unit coupled to the communication module. The protection settings and the breaker information are received upon powering-on the trip unit. The non-transitory memory device is configured to store the protection settings and the breaker information associated with the circuit breaker. The memory controller is configured to cause the protection settings and the breaker information received to be written to the non-transitory memory device.
1. A system comprising:
a circuit breaker comprising a circuit breaker information module (BIM), a communication channel, and a trip unit;
the trip unit configured to store protection settings and to control an operation of the circuit breaker therewith, the trip unit being selectively removable from the circuit breaker;
the BIM communicatively coupled to the trip unit via the communication channel, and configured to store protection settings and circuit breaker information therein;
wherein the protection settings and breaker information are stored in the BIM in the event the trip unit is removed from the circuit breaker and the BIM is further configured to provide, in response to a determination that the trip unit has been installed into the system after a previous trip unit has been removed from the system, sensor characterization data that was written to the BIM by the previous trip unit, wherein the sensor characterization data is indicative of settings usable by the trip unit to communicate with a sensor of the system.
2. The system in accordance with claim 1 , wherein said trip unit comprises a memory device configured to store the protection settings.
3. The system in accordance with claim 1 , wherein said communication channel comprises a full-duplex channel.
4. The system in accordance with claim 1 , wherein said trip unit comprises the sensor and the sensor is configured to generate signals upon which control of said circuit breaker is based.
5. The system in accordance with claim 1 , wherein said trip unit is configured to update the protection settings based on information received from the BIM.
6. The system in accordance with claim 5 , wherein said trip unit is configured to:
store updated breaker information in a trip unit memory device;
transmit the updated breaker information to said BIM over said communication channel; and
generate a warning if no indication of a successful write of the updated breaker information to said BIM is received at said trip unit.
7. The system in accordance with claim 1 , wherein a powering-on of the trip unit triggers an update of information from the trip unit to the BIM.
