Circuit protection system

1. A method of providing protection against arc flash on a low voltage power circuit including a circuit breaker having a specified trip function for responding to a fault, the method comprising:

overriding the specified trip function with an altered trip function determined by a central control processing unit based on a location of the fault relative to the circuit breaker such that arc energy in the fault during a trip with the altered trip function is reduced when compared with arc energy during a trip with the specified trip function;

wherein the overriding the specified trip function with an altered trip function further comprises performing an adjustment of a trip curve of the circuit breaker in-situ via a human-machine-interface and the central control processing unit over a data network, the data network being disposed external of the circuit breaker; and

identifying a characteristic associated with the circuit breaker via a tag associated with the circuit breaker, the tag being configured to interface with the data network to communicate the associated characteristic to the central control processing unit.

2. The method of claim 1 , wherein the low voltage power circuit comprises a main circuit breaker and a feeder breaker, the circuit breaker having a specified trip function being one of the main breaker and the feeder breaker.

3. The method of claim 1 , wherein the circuit breaker is positioned upstream from the fault.

4. The method of claim 1 , wherein the altered trip function is a modified sum of a pre-defined delay time and a clearing time of a downstream circuit.

5. The method of claim 4 , wherein the clearing time depends on a type of downstream circuit breaker.

6. The method of claim 4 , wherein the sum is modified by a value determined by the central control processing unit.

7. A low voltage circuit breaker configured to protect from arc flash resulting from faults in a protected low voltage power circuit, comprising;

separable contacts;

at least one current sensor sensing current in the protected low voltage power circuit;

a trip unit responsive to the at least one current sensor tripping open the associated separable contacts in response to a specified trip function;

a transmission module in operable communication with the circuit breaker and a central control processing unit over a data network external to the circuit breaker, the transmission module being configured to transmit a communication signal, when in use, to override the specified trip function with an altered trip function, the altered trip function being determined by the central control processing unit based on a location of the fault relative to the circuit breaker such that arc energy in the fault during a trip with the altered trip function is reduced when compared with arc energy during a trip with the specified trip function; and

wherein at least one of the circuit breaker and the at least one current sensor is labeled with a tag configured to interface with the data network to communicate a characteristic associated with the at least one of the circuit breaker and the at least one current sensor to the central control processing unit.

8. The method of claim 2 , further comprising:

collecting a characteristic associated with the main circuit breaker and the feeder circuit breaker at substantially a same instant of time.

9. The method of claim 8 , wherein the collecting comprises communicating a synchronization instruction from the central control processing unit over the data network.

10. The method of claim 8 , further comprising:

moving a collected characteristic to the central control processing unit prior to a next message being scheduled to arrive.

11. The low voltage circuit breaker of claim 7 , wherein the tag is configured to interface with the data network via a synchronization instruction generated via a synchronizing clock associated with the central control processing unit.

12. The circuit breaker of claim 7 , wherein the circuit breaker is positioned upstream from the fault.

13. The circuit breaker of claim 7 , wherein the altered trip function is a modified sum of a pre-defined delay time and a clearing time of a downstream circuit.

14. The circuit breaker of claim 13 , wherein the clearing time depends on a type of downstream circuit breaker.

15. The circuit breaker of claim 13 , wherein the sum is modified by a value determined by the central control processing unit.
