Product FAQs
8 answersWhat is the modern replacement for the legacy KGL32225?
The Square D KGL32225 is a legacy K-frame breaker. It has been replaced by the modern PowerPact J-Frame series, specifically catalog number JGL36225.
Can the KGL32225 be installed in an I-Line panelboard?
No. The KGL32225 is a unit mount, feed-thru circuit breaker. It is designed to be bolted directly to a backpan in switchboards, motor control centers, or enclosures. I-Line panelboards require a breaker with plug-on line-side jaws.
What does the "G" in the KGL32225 catalog number signify?
In Square D legacy K-frame nomenclature, the "G" designates the interrupting capacity tier. For this specific breaker, it indicates a 65kAIC rating at 240VAC.
What are the wire size and material requirements for the KGL32225 lugs?
The standard lugs accept wire gauges from 6 AWG up to 350 kcmil. They are dual-rated for terminating both aluminum and copper (Al/Cu) conductors.
Are the trip settings on the KGL32225 adjustable?
No. This thermal-magnetic breaker features fixed long-time and fixed instantaneous (LI) trip elements. Neither the thermal overload nor the magnetic short-circuit thresholds can be adjusted in the field.
How are the line and load connections made on the KGL32225?
Because it is a feed-thru, unit mount breaker, both the line and load sides utilize mechanical lugs for hardwiring. It does not plug onto a busbar.
What equipment is the KGL32225 designed to protect?
This 3-pole, 225A breaker is commonly used for main or feeder circuit protection in Square D switchboards, motor control centers, and standalone enclosures operating at 240VAC.
What safety verifications are required before installing the KGL32225?
Always de-energize the equipment before installation. Verify that the available fault current at the installation point does not exceed the breaker's 65kAIC maximum interrupting rating at 240VAC.
