Product FAQs
6 answersWhat panelboards are compatible with the HJA36150SA circuit breaker?
This I-Line style plug-in breaker is designed for use in Square D I-Line panelboards and switchboards. The plug-on line side design allows for faster installation compared to traditional bolt-on breakers.
What does the SA suffix mean in the HJA36150SA catalog number?
The SA suffix indicates that this breaker includes a factory-installed 120VAC shunt trip, allowing the breaker to be opened remotely via an external control signal.
Can the HJA36150SA replace older Square D circuit breakers?
Yes, this PowerPacT H-frame breaker serves as the direct modern replacement for the legacy KA361501021 K-frame circuit breaker.
How does the HJA36150SA mount into a panel?
It features an I-Line style plug-in connection on the line side, which snaps directly onto the panelboard bus, and uses standard mechanical lugs on the load side.
What is the phase connection for this 3-pole I-Line breaker?
The HJA36150SA has a standard ABC phase connection, which is typical for 3-pole breakers installed in Square D I-Line panelboards.
Is the HJA36150SA a current-limiting circuit breaker?
Yes, PowerPacT H-frame breakers with the J interrupting class (HJA) are current-limiting. This design helps protect downstream devices by reducing the peak let-through current during a short-circuit fault.
