Schneider QOB390VH – Frequently Asked Questions

1) Will a Schneider QOB3 breaker fit a plug-on QO load center?
No. The QOB3 three-pole breakers are bolt-on devices, so they mount by screw to the bus of a panelboard prepped for bolt-on breakers. A plug-in QO load center with stab-on bus will not take them. For a plug-on panel you need the plug-on QO 3-pole version instead.
2) What amperages does the Schneider QO 3-pole bolt-on VH breaker come in?
Twelve ratings are offered: 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125 and 150 amps. Part numbers follow the pattern QOB3 plus the amp rating plus VH, for example QOB320VH at 20 A and QOB3150VH at 150 A. Note there is no 25 A or 35 A in this group, so size up or down accordingly.
3) Is 22kA interrupting rating enough for my service, or do I need a higher AIC breaker?
The VH suffix on these QO 3-pole breakers denotes the 22,000 A interrupting capacity at 120/240VAC. If your available fault current at the panel, per the utility or the coordination study, is at or below 22kA, this breaker is rated for it. Above that you need a higher-AIC device; a standard 10kA QO breaker would be under-rated in that spot.
4) Can I use a QO 3-pole breaker on a 208Y/120 three-phase panel?
Yes. The QO 3-pole breaker is rated 120/240VAC and all three poles trip together, which is what a three-phase branch circuit needs. It is a low voltage device, so it is not suited to 480Y/277V systems; those call for a breaker rated for that voltage class.
5) Is this a plain thermal-magnetic breaker or does it have GFCI or arc fault protection?
Standard overcurrent protection only. The circuit breaker type is listed as standard with a Standard function option, meaning overload and short circuit protection with no ground fault or arc fault sensing built in. If the circuit needs GFCI or AFCI, you need a dedicated QO GFI or CAFI device.
6) What ambient temperature are these QO breakers rated to, and does that matter in a hot mechanical room?
Rated for 40 degrees C ambient air temperature in operation. In a hot electrical closet or rooftop enclosure running above that, thermal trip curves shift and you should account for derating in your load calculation rather than assuming full nameplate ampacity.
7) Do these Schneider QO breakers meet RoHS and halogen-free requirements for a green building spec?
They do carry Green Premium status, are EU RoHS compliant, halogen free, mercury free and free of toxic heavy metals, with environmental disclosure reference ENVPEP2111016 available for documentation. One caveat for a submittal package: the REACH status states the reference contains Substances of Very High Concern above the threshold.
8) I need to replace one pole of a three-phase circuit. Can I just swap in a single-pole QO?
No. A three-phase branch circuit requires simultaneous disconnection of all ungrounded conductors, which is what the 3-pole common-trip construction of the QOB3 provides. Three separate single-pole breakers would leave two legs energized when one trips. Replace it with the same amp rating QOB3 VH device.
9) Can a QOB3 breaker be repaired or serviced if it keeps tripping?
No. Serviceability on these QO miniature circuit breakers is listed as no, so they are replace-only units. A breaker that trips repeatedly after the fault is cleared, or one that has interrupted a heavy fault, gets swapped for a new one of the same amp rating.
10) Where are Schneider QO 3-pole bolt-on breakers made?
Country of origin is Mexico. That matters for buyers with domestic-content or trade-documentation requirements on a government or institutional purchase order.
11) How long can I expect a QO breaker to last before a planned panel refresh?
Average life duration is published as 15 years. For an MRO or property management team on a replacement cycle, that is the figure to budget against for breakers sitting in a commercial panelboard at normal load.
