The Milbank UQFP-125 is a 2 Pole thermal magnetic molded case circuit breaker with a current rating of 125 Amps and a voltage rating of 240VAC. It has an interrupting rating of 10kAIC. The UQFP-125 has a plug-on mounting type.
What legacy circuit breakers can the Milbank UQFP-125 replace?
The UQFP-125 replaces several obsolete plug-in main breakers, including Challenger QFP, Westinghouse WFP, Thomas & Betts TBFP, General Switch GDP, and specific Zinsco, Sylvania, and Unicorn models.
Is the UQFP-125 compatible with panels requiring offset lugs?
No. If your existing main breaker requires extended, offset, or side entrance lugs (often designated as type T, 2T, M, or K), this standard plug-in breaker will not fit the enclosure.
What are the acceptable wire sizes for the UQFP-125 lugs?
The lugs accommodate 3 AWG to 1 AWG copper conductors or 1 AWG to 1/0 AWG aluminum conductors.
How does the UQFP-125 differ from the UQFB-125?
The UQFP-125 utilizes a plug-on mounting configuration for parallel main applications. The UQFB-125 is the bolt-on equivalent designed for panels that require a bolted connection.
Is the UQFP-125 suitable for series main applications?
No. The standard UQFP series is intended for parallel main circuit breaker applications. If your setup requires series main applications with feed-through capability, you need the UQFP-M series variant.
Does the UQFP-125 feature an interchangeable trip unit?
No, this breaker has a fixed thermal-magnetic trip unit and is not interchangeable.
