Product FAQs
6 answersWhat panelboards are compatible with the JGA36150 circuit breaker?
This I-Line plug-on breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It cannot be installed in standard residential load centers or unit-mount enclosures.
How are the line and load connections configured on this breaker?
The JGA36150 features I-Line plug-on jaws on the line side that connect directly to the panelboard bus. The load side is equipped with mechanical lugs that accept 4 AWG to 4/0 AWG aluminum or copper conductors.
What does the "G" in the JGA36150 catalog number indicate?
In the PowerPact J-Frame nomenclature, the "G" designates the interrupting capacity tier. This model is rated to safely clear faults up to 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Are the trip curve settings adjustable on the JGA36150?
Yes, while the thermal overload protection is fixed at the 150-amp continuous rating, the instantaneous magnetic trip is adjustable. This allows you to customize the short-circuit protection threshold for your specific load or motor starting requirements.
Can the JGA36150 replace older Square D legacy I-Line breakers?
Yes, this PowerPact J-Frame breaker is the direct modern replacement for obsolete 150-amp K-frame (KA36150) I-Line circuit breakers. It mounts directly to the same standard I-Line bus system.
What is the bus phase connection for the standard JGA36150?
This 3-pole I-Line breaker is factory-configured for a standard ABC phase connection to the panelboard bus.
