Description
Part of the legacy Q-Frame lineup, this 60A unit mount molded case circuit breaker delivers reliable thermal-magnetic protection for commercial and industrial applications. It installs into individual enclosures and older OEM panels requiring a 6.25-inch height profile. While the modern QOU360 serves as a functional substitute, upgrading requires mounting modifications because the newer model is three inches shorter. Features include a Visi-Trip indicator and a 10kA interrupt rating at 240VAC.Specifications

Product FAQs
4 answersIs the Q1U360 still manufactured, and what is the modern replacement?
The Q1U360 is a legacy Q-Frame breaker and is no longer manufactured. The modern Square D QOU360 serves as a functional electrical substitute, but because the QOU360 is three inches shorter, upgrading requires mounting modifications to fit the original 6.25-inch height profile.
Can I install the Q1U360 in a standard Square D QO load center?
No. The Q1U360 is a unit-mount, feed-thru breaker designed for individual enclosures and older OEM panels. It does not feature the plug-in or bolt-on mounting required for standard QO or NQOD load centers.
What wire gauge and material do the Q1U360 terminals accept?
The terminal lugs are rated for both aluminum and copper (Al/Cu) conductors, accepting wire sizes from 14 AWG to 2 AWG.
Are the trip settings on the Q1U360 adjustable?
No. This breaker features a fixed thermal-magnetic trip unit providing long-time and instantaneous (LI) protection. The trip settings cannot be adjusted in the field.
