Description
Built for demanding electrical systems, the QJL22150 is a 150A molded case circuit breaker from the Square D PowerPacT series. It provides essential thermal-magnetic protection with fixed long-time and instantaneous (LI) trip functions for commercial applications. This two-pole, unit-mount breaker fits into compatible Square D Q-Frame enclosures, panelboards, and switchboards. It acts as an exact substitute for the older Q2L2150 model. Rated for 100kAIC at 240VAC, it is HACR-rated.Specifications

Product FAQs
8 answersWhat is the recommended tightening torque for the lugs on the QJL22150?
The factory-installed lugs, which accept 4 AWG to 300 kcmil aluminum or copper wire, require a tightening torque of 247.8 lb-in (28 N-m).
Can the QJL22150 breaker be reverse fed?
Yes, Square D Q-frame thermal-magnetic circuit breakers can be forward or reverse fed, making them suitable for back-fed main applications when properly labeled and secured.
Which Square D panelboards are compatible with this Q-frame breaker?
This unit-mount Q-frame breaker is commonly used in Square D NQ panelboards when equipped with the appropriate main breaker or sub-feed adapter kits, such as the NQMB2Q. It is also compatible with standard Q-frame enclosures and switchboards.
What is the difference between the QJL22150 and the QBL, QDL, or QGL versions?
The prefix indicates the interrupting rating (AIC) at 240V. The QBL is rated at 10kA, QDL at 25kA, QGL at 65kA, and the QJL provides the highest rating at 100kA. All share the same physical dimensions and mounting.
Is the QJL22150 rated for 100% continuous duty?
No, standard Square D Q-frame molded case circuit breakers are rated for 80% continuous duty unless explicitly marked otherwise. Continuous loads should not exceed 120 amps for this 150A breaker.
Is this breaker HACR rated for HVAC equipment?
Yes, Square D Q-frame molded case circuit breakers are HACR type rated, making them suitable for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
Does the QJL22150 provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic circuit breaker providing long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include GFCI or AFCI capabilities.
Are the thermal and magnetic trip settings adjustable on the QJL22150?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The instantaneous magnetic trip is factory set and cannot be adjusted in the field.
