Milbank UQFB-A-100-X1 – Frequently Asked Questions

1) What amp ratings does the Milbank UQFB-A circuit breaker come in?
Four ratings: 100, 125, 150 and 200 amps, ordered as UQFB-A-100-X1, UQFB-A-125-X1, UQFB-A-150-X1 and UQFB-A-200-X1. All are 2-pole, 240VAC, single phase, with the same 10,000 AIC interrupting capacity, so the amp rating is the only thing you pick. Match it to the service or feeder you are protecting.
2) Will the Milbank UQFB-A breaker fit in my meter socket?
It is built as a metering accessory breaker, F-Frame, with line tangs that have threaded inserts and unthreaded load tangs. That tang arrangement is what lets it land in Milbank metering equipment rather than a standard load center. The body measures 7.438 inches high, 3.281 inches long and 3 inches wide, so check that against the breaker pocket in your socket or pedestal before ordering.
3) Can I use this 240V 2-pole breaker on a 208Y/120 three phase service?
No. The UQFB-A is rated 240 volts AC, single phase, 60 Hz, with two poles. It protects a single phase 120/240 service or feeder. For three phase distribution you need a 3-pole device rated for the system voltage, not this one.
4) Is 10,000 AIC enough for my service entrance?
The UQFB-A interrupts 10,000 amperes of available fault current. On most residential and light commercial 120/240V services fed from a typical utility transformer that is sufficient, but on a service close to a large transformer the available fault current can exceed 10kA. Get the available fault current from the utility and compare it to the 10,000 AIC figure; if it is higher, this breaker is not the right device.
5) What kind of trip protection does this Milbank breaker use, and does it need auxiliary contacts?
Thermal magnetic trip: the thermal element handles sustained overloads, the magnetic element clears short circuits instantly. It ships with no auxiliary contacts, so if you need a status signal back to a panel or controller this unit will not provide it. Operation is by a standard lever handle.
6) How do the conductors terminate on this breaker, line and load?
Lug to lug on both ends. The line side tangs carry threaded inserts for a bolted utility connection; the load side tangs are unthreaded. Plan your line side hardware accordingly, since the two ends are not interchangeable.
7) Is the Milbank UQFB-A breaker UL Listed, and what is the ambient temperature rating?
UL Listed, which is what most inspectors want to see on a service entrance device. It is rated for operation at 40 degrees Celsius ambient. In a hot attic, rooftop or unventilated enclosure running above that, derating applies and the thermal element will trip earlier than the nameplate amperage suggests.
8) Is a non-metallic breaker housing a problem in an outdoor meter installation?
No. The UQFB-A body is non-metallic, which gives corrosion resistance and dielectric insulation, an advantage over a metal case in coastal or damp service locations. Weather protection still comes from the meter socket or enclosure it mounts in, not from the breaker itself.
9) What UNSPSC code should I use for the Milbank UQFB-A on a purchase order?
UNSPSC 39121601. Milbank lists the breaker under product family code MSCB, useful when cross-referencing against their metering accessory line in a procurement system.
