This component simulates of single-phase circuit breaker operation. The ON (closed) and OFF (open) resistance of the breaker must be specified along with its initial state.
This component is controlled through a named input signal (default is BRK), where the breaker logic is:
0 = ON (closed)
1 = OFF (open)
The breaker control can be configured automatically by using the Timed Breaker Logic component, or the Sequencer components. The breaker may also be controlled manually through the use of on-line controls, or through a more elaborate control scheme.

|
Open Possible at Any Current? |
|
Choice |
|
Select Yes or No. If No is selected, the breaker will wait for the absolute value of the current to be less than the specified Current Chopping Limit. |

Use Pre-Insertion Resistance? |
|
Choice |
|
Select Yes or No. See Pre-Insertion Resistance for more details. |

Breaker Main DataBreaker Main Data
Breaker OPEN Resistance |
|
REAL |
Constant |
Enter a large value to represent the OFF (open) state of the breaker. This should be in the order of 1.0 x 106 (default) [W] |
|
|
|
|
|
Breaker CLOSED Resistance |
|
REAL |
Constant |
Enter a small value to represent the ON (closed) state of the breaker. This should be in the order of 1.0 x 10-3 (default). See Ideal Branch for more details [W] |
Pre-Insertion DataPre-Insertion Data
NOTE: These parameters are enabled only if Use Pre-Insertion Resistance? | Yes is selected. See Pre-Insertion Resistance for more details.
Pre-Insertion Resistance |
|
REAL |
Constant |
The value of Pre-insertion resistance. This should be smaller than the OFF (open) resistance and larger than the ON (closed) resistance [W] |
|
|
|
|
|
Time Delay for Closing Breaker |
|
REAL |
Variable |
Enter the time delay between the ON (closed) signal and actual closing of the breaker. After this time delay, breaker will close on to the pre-insertion resistance [s] |
|
|
|
|
|
Time Delay for Bypassing Pre-Ins. |
|
REAL |
Constant |
Enter the time delay between the ON (closed) signal and the bypassing of the pre-insertion resistance. If this time delay is smaller than the Time Delay for Closing Breaker, the pre-insertion resistance will not be inserted before closing the breaker [s] |
|
|
|
|
|
Post-Insertion Removal |
|
Choice |
|
Select at next current zero or after specified time. This control specifies whether to remove the post insertion resistance at the next zero-crossing of current or following a specified time. |
|
|
|
|
|
Minimum Time for Post-Ins Removal |
|
REAL |
Variable |
Specifies the time after which the post insertion resistance is removed [s]. This field is enabled only if Post-Insertion Removal | Yes is selected. |
