Product FAQs
6 answersWhat type of trip unit is equipped on the PJL36120U44A breaker?
This breaker includes a MicroLogic 6.0A electronic trip unit. It provides integrated ammeter functionality alongside adjustable LSIG (Long-time, Short-time, Instantaneous, and Ground-Fault) protection for precise system coordination.
What is the recommended terminal tightening torque for the PJL36120U44A?
The factory lugs require a tightening torque of 442.5 lb-in (50 N.m) when using 3/0 AWG to 500 kcmil aluminum or copper conductors.
What is the correct replacement lug kit for this 1200A P-Frame breaker?
The standard mechanical lug kit for this unit is part number AL1200P25K, which includes a set of three lugs that each accept four 3/0 AWG to 500 kcmil conductors.
Which enclosures and switchboards are compatible with the PJL36120U44A?
This feed-thru unit mount breaker is designed for installation in Square D QED switchboards, Model 6 motor control centers, and PowerPacT P-Frame enclosures.
Is the PJL36120U44A circuit breaker rated for 80% or 100% continuous current?
This standard catalog number is 80% rated. For a 100% continuous current rating, the equivalent part number requires a C suffix (PJL36120CU44A).
Can the PJL36120U44A be installed in an I-Line panelboard?
No, this specific breaker features a unit-mount, feed-thru design. Breakers intended for I-Line panelboards require a plug-on mounting base, such as the PJA frame variants (for example, PJA36120U44A).
