Product FAQs
7 answersWhat equipment is compatible with the KGL32150 circuit breaker?
This legacy K-frame breaker is designed for use in Square D switchboards, motor control centers, enclosures, and panelboards configured for unit-mount breakers.
Is the Square D KGL32150 still manufactured, or is there a modern replacement?
The KGL32150 is part of the legacy K-frame family. While exact replacements are often sourced for existing panels, Schneider Electric recommends the modern PowerPact H-frame or J-frame series for new installations and system upgrades.
What wire sizes are supported by the terminals on the KGL32150?
The standard lugs on this breaker accept either aluminum or copper conductors ranging from 6 AWG to 350 kcmil.
How does a feed-thru connection differ from an I-Line mount?
As a feed-thru (unit-mount) breaker, the KGL32150 bolts directly to the backpan of the enclosure or panelboard and uses cabled connections for both line and load sides. It does not plug into a Square D I-Line busbar system.
What protection is provided by the LI trip function on this breaker?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short circuit protection. On the KGL32150, both the thermal and magnetic trip settings are fixed.
Can the KGL32150 be applied to 480V electrical systems?
No, this specific breaker has a maximum voltage rating of 240VAC. It is not rated for use on 480V or 600V systems.
Does the KGL32150 include integrated ground fault protection?
No, this model features a standard thermal-magnetic trip unit. It does not provide equipment ground fault or personnel ground fault protection.
