Milbank UQFB-200-X – Frequently Asked Questions

1) What amp ratings does the Milbank UQFB-X circuit breaker come in?
The UQFB-X is offered in four ratings: 100A (UQFB-100-X), 125A (UQFB-125-X), 150A (UQFB-150-X) and 200A (UQFB-200-X). All four are 2-pole, 240 VAC, single phase, with the same 10,000 AIC interrupting capacity. Pick the rating that matches the service or feeder it is protecting, since the frame and footprint do not change across the four.
2) Will a 10K AIC breaker be enough fault current rating for my service?
The UQFB-X interrupts 10,000 amperes. That covers the great majority of residential and light commercial 120/240V single phase services, but if the utility's available fault current at your service point exceeds 10,000 amps, this breaker is not the right device and you need a higher AIC unit. Get the available fault current figure from the utility before you commit on a service upgrade.
3) Can I use the Milbank UQFB-X on a 480V or three phase system?
No. This is a 240 VAC, 60 Hz, single phase, 2-pole device. It is built for 120/240V single phase work only. A 480V or three phase installation needs a different breaker entirely.
4) What does the "unthreaded tangs" on the line side of the UQFB-X mean for my wiring?
The line side of the UQFB-X terminates in unthreaded tangs rather than a threaded stud, which is how it lands into Milbank metering accessory equipment. The breaker itself is a lug-to-lug connection device, so your load side conductors land in a lug. If your socket or pedestal was built for a threaded-tang breaker, this is the wrong variant.
5) What are the dimensions of the Milbank UQFB-X breaker so I know it will fit the enclosure?
It measures 7.438 inches in height, 3.281 inches in length and 3 inches in width. Those dimensions are the same on all four amp ratings, so a 100A and a 200A take the same space in the can.
6) Is the UQFB-X thermal magnetic or electronic trip, and does it matter here?
Thermal magnetic. The bimetal handles sustained overload, the magnetic element handles a short circuit instantly. For a metering or service disconnect application on a 120/240V single phase system that is the standard trip unit; you do not get adjustable electronic settings with this device.
7) Does the Milbank UQFB-X have auxiliary contacts for alarm or status monitoring?
No auxiliary contacts. The UQFB-X is a straight overcurrent device with a lever actuator, so there is no built in contact for remote breaker status, shunt trip or alarm signalling. If your spec calls for breaker position monitoring, this is not the device.
8) Is the Milbank UQFB-X UL Listed, and what ambient temperature is it rated at?
UL Listed, and the stated operating temperature is 40 degrees Celsius. That 40 C figure is the ambient the breaker's current rating is based on, so a hot attic, a sun-exposed meter pedestal or a tight enclosure running above it will affect how the breaker behaves under load.
9) Is the housing on this Milbank breaker metal or plastic, and will it hold up in an outdoor meter enclosure?
The UQFB-X uses a non-metallic housing, which is what you want in a utility metering environment where moisture and corrosion are in play. The non-conductive case also keeps the breaker electrically isolated from the enclosure it mounts in.
