Milbank UQFB-100-X-MOD – Frequently Asked Questions

1) What amperages does the Milbank UQFB 2-pole breaker come in?
Five ratings: 100, 125, 150, 175 and 200 amps, ordered as UQFB-100-X-MOD, UQFB-125-X-MOD, UQFB-150-X-MOD, UQFB-175-X-MOD and UQFB-200-X-MOD. All share the same 2-pole, 240 VAC, 10,000 AIC F-frame body, so the amp rating is the only thing you pick.
2) Will this Milbank breaker work in a 120/240V single-phase residential service?
Yes. It's rated 240 volts AC, single phase, 60 Hz, with two poles, which is exactly a 120/240V single-phase service. It is not a three-phase device.
3) Is 10,000 AIC enough for my service, or do I need a higher interrupting rating?
The UQFB is a 10,000 ampere interrupting capacity device. That covers the great majority of residential and light commercial services, but if your utility's available fault current at the meter exceeds 10 kA, this breaker is not the right choice and you need a higher-AIC unit. Get the available fault current figure from the POCO before you commit.
4) How does the Milbank UQFB connect into a meter socket or panel?
It's a bolt-on breaker with line side unthreaded tangs and a lug-to-lug arrangement, so the line side lands on the socket's tang connection rather than stabbing onto a bus. That means the enclosure has to be prepped for a tang-type bolt-on breaker; it will not clip into a plug-on load center.
5) What are the dimensions of the Milbank UQFB circuit breaker for fitting inside an enclosure?
The breaker measures 7.438 inches in height, 3.281 inches in length and 3 inches in width. Check those against the interior clear space of your meter socket or pedestal before cutting the opening, since the same body size applies across all five amp ratings.
6) What does thermal magnetic trip mean on this Milbank breaker, and is it adjustable?
Thermal magnetic means two trip mechanisms in one: a thermal element that responds to sustained overload and a magnetic element that reacts instantly to a short circuit. It's a fixed-trip device at its rated amperage, operated by a lever handle, with no auxiliary contacts for remote status or alarm. If you need electronic adjustable trip settings or aux contacts for a BMS, this isn't that breaker.
7) Is the Milbank UQFB breaker UL Listed for service entrance metering equipment?
The UQFB is UL Listed and is catalogued as a metering accessory, which is the role it's built for: main disconnect and overcurrent protection inside Milbank metering equipment. Inspectors on meter-main work typically want that UL Listing plus the utility's approval of the socket assembly itself.
8) Is the housing on the Milbank UQFB metal or plastic?
Non-metallic housing. The molded case provides the insulation between the poles and the enclosure, which is why the unit bolts directly into a metal meter socket without an additional insulating barrier.
