Product FAQs
5 answersWhat does the HM suffix indicate on the QO115HM breaker?
The HM suffix stands for High Magnetic. These breakers have a magnetic trip point set significantly higher than standard QO breakers to accommodate high initial inrush currents without nuisance tripping. They are commonly used for specific fluorescent lighting or individual dimmer applications.
Which load centers and panelboards are compatible with the QO115HM?
This plug-on breaker is designed for use in Square D QO load centers, as well as NQ and NQOD panelboards. It is not compatible with Homeline panels.
Does the QO115HM feature a Visi-Trip indicator?
Yes, it includes the standard QO Visi-Trip feature. When the breaker trips, the handle moves to a midpoint position and a red indicator window appears, allowing for quick identification of the tripped circuit.
Is the QO115HM suitable for HVAC equipment?
Yes, QO circuit breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment that requires an inverse time breaker approved for group installation.
Is the QO115HM rated for switching duty (SWD)?
Yes, this 15-amp breaker is SWD rated, meaning it is approved for switching 120V fluorescent lighting loads on and off on a regular basis.
