5.6.3.2 C.B Rating (Circuit Breaker Rating)
Figure 75 – C.B Rating Setting
Purpose:
The Circuit Breaker Rating setting helps prevent in-rush induced nuisance tripping of the circuit breaker
immediately upstream of the controller. The Circuit Breaker Limiting alarm, if enabled, will only inform the
user that circuit breaker limiting is active.
Range: 1.0 A to 100.0 A for Current Turns Ratio 1:1
Default: 30.0 A
IMPORTANT:
The maximum C.B Rating supported by the Elexant 4010i/4020i is a function of the external current turn
ratio (see Section 5.8.1.2).
Procedure:
Touch the C.B Rating text box to display the numeric pad and set the numeric value.
Touch the Enable check box to turn on/off the Alarm indication or touch the Latch check box to
configure a latching or a non-latching type of alarm. When the latching is selected, the alarm will need
to be manually reset each time the corresponding alarm occurs.
