If a 48-channel Sensor IQ panel is fed with a 400A feed, a 65kA breaker must be used. However, if you are feeding a Sensor IQ 48-channel panel with a 100A or 200A feed, the 22kA breakers are OK to use.
Below is a list of the Main Breaker kits offered by ETC.
Main Breaker options – 22kA
Main Breaker options – 65kA
If you have any questions or concerns about this information, please contact ETC Technical Services.
