Product FAQs
7 answers
What enclosures are compatible with the QBL22175 circuit breaker?
The QBL22175 is designed for use in Square D Q2 enclosures, as well as compatible switchboards, control panels, and meter mains.
What is the wire size and torque specification for the QBL22175 lugs?
The box-type lugs accept 4 AWG to 300 kcmil aluminum or copper wire. The tightening torque is 248 lb-in (28 N.m).
Are the lugs on the QBL22175 removable or replaceable?
No, PowerPacT Q-frame circuit breakers feature factory-installed, non-replaceable box-type lugs.
What is the difference between the QBL, QDL, QGL, and QJL circuit breakers?
These are all PowerPacT Q-frame breakers that share the same physical dimensions but have different interrupting ratings at 240V. The QBL is rated at 10kA, QDL at 25kA, QGL at 65kA, and QJL at 100kA.
Is the QBL22175 a direct replacement for older Q2 series breakers?
Yes, the PowerPacT Q-frame circuit breaker is a direct replacement for legacy Square D Q2 Series devices.
How does a unit mount breaker like the QBL22175 differ from an I-Line breaker?
A unit mount breaker features lugs on both the line and load ends for cabled applications and mounts individually on a plate. An I-Line breaker plugs directly onto a bus on the line side and is used exclusively in I-Line panelboards and switchboards.
Can the QBL22175 be used on a 120/240V single-phase system?
Yes, this 2-pole breaker is rated for 240VAC and is suitable for standard 120/240V single-phase applications.
