Product FAQs
6 answersWhat panels are compatible with the QO115VH circuit breaker?
This plug-on breaker is designed exclusively for use in Square D QO Load Centers, NQ Panelboards, and Speed-D Switchboards. It is not compatible with Homeline or other manufacturer panels.
What does the VH designation mean in the QO115VH catalog number?
The VH suffix indicates a high interrupting rating of 22kAIC at 120/240VAC. Standard QO breakers, such as the QO115, typically feature a 10kAIC rating. The VH version is required in electrical systems with higher available fault currents.
Can the QO115VH be used to replace a standard QO115?
Yes. The QO115VH shares the exact physical dimensions and plug-on mounting style as the standard QO115. It serves as a direct replacement while providing an upgraded 22kAIC interrupting capacity.
Does the QO115VH feature a tripped circuit indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips, the handle snaps to a center position and a highly visible red indicator appears in the window, allowing for rapid identification of the faulted circuit.
What are the wire size and torque specifications for the QO115VH terminals?
The pressure plate terminals accept 14 AWG to 8 AWG aluminum or copper conductors. The recommended tightening torque for these connections is 40.7 lbf-in (4.6 N-m).
Is the QO115VH rated for switching fluorescent lighting loads?
Yes, 15A and 20A 1-pole QO breakers are SWD (Switching Duty) rated, making them suitable for switching 120VAC fluorescent lighting loads on a regular basis.
