What is the replacement 100A main breaker for the C1620QRB combination service entrance device?

Issue:
Old design repair parts

Product Line:
Combination Service Entrance Devices

Environment:
Repair parts

Cause:
Maintenance

Resolution:
The original main breaker was a Q12100, which is obsolete, no longer available with no direct replacement. The Q12100 can be replaced with a QO2100. The QO2100 is smaller(about half the length) than the Q12100, so this change will provide two extra space in load center.
