Product FAQs
7 answersWhat panelboards are compatible with the Q12100VH circuit breaker?
This plug-in breaker is designed exclusively for use in legacy Square D Q1 panelboards and NQO panelboards. It will not fit in modern QO or Homeline load centers.
Can I use a modern QO2100VH to replace the Q12100VH?
No, not directly. The Q12100VH is an original wide-frame breaker designed for legacy enclosures. A modern QO2100VH has a narrower profile and will not physically fit a Q1 or NQO panelboard without retrofitting.
What does the VH suffix indicate on the Q12100VH?
The VH suffix denotes a high interrupting rating. While standard Q1 breakers typically have a 10 kAIC rating, the Q12100VH is rated to safely interrupt up to 22,000 amps (22 kAIC) at 240VAC.
What wire sizes are accepted by the lugs on the Q12100VH?
The breaker terminals accept copper wire from 6 AWG to 1/0 AWG, and aluminum wire from 4 AWG to 1/0 AWG.
Is the Q12100VH suitable for use with HVAC equipment?
Yes, this breaker is fully HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment that requires group installation and inverse time circuit breakers.
Does the Q12100VH include a tripped circuit indicator?
Yes, this breaker features a Visi-Trip indicator that provides a clear visual alert when the breaker has tripped, allowing for rapid fault detection in the panel.
Is the Q12100VH a direct replacement for the standard Q12100?
Yes, the Q12100VH shares the same physical dimensions and plug-in mounting as the standard Q12100, but offers an upgraded 22 kAIC interrupting rating compared to the standard 10 kAIC rating.
