The terminal lugs on this breaker accept both copper and aluminum conductors, accommodating wire gauges from 4 AWG up to 300 kcmil.
What are the physical dimensions of the Q232175 circuit breaker?
This Q-Frame breaker measures approximately 7.88 inches in height, 4.5 inches in width, and 4.31 inches in depth. Verifying these dimensions is critical when replacing breakers in legacy equipment.
Does the Q232175 feature a visual trip indicator?

How does the thermal magnetic trip unit function on the Q232175?
The fixed thermal magnetic trip unit provides long-time protection against sustained overloads and instantaneous protection against short circuits. Both the thermal and magnetic trip elements are fixed and non-adjustable.
Can I install the Q232175 in a standard QO or Homeline load center?
No. The Q232175 utilizes an I-Line plug-on mounting style and will not fit in residential QO or Homeline load centers. It is strictly intended for commercial I-Line distribution equipment.
