Product FAQs

6 answers
How much mounting space does this 3-pole breaker occupy in an I-Line panelboard?

The HJA36150 requires 4.5 inches of vertical bus space, as each pole takes up 1.5 inches of mounting space.

Can the HJA36150 replace legacy F-frame I-Line breakers?

Yes. The PowerPacT H-frame is designed as the direct plug-on replacement for older Square D F-frame I-Line circuit breakers, such as the FA, FH, and FC series, since they share the exact same 4.5-inch mounting space.

What does the "J" in the HJA36150 catalog number signify?

In the Square D PowerPacT nomenclature, the "J" denotes the interrupting capacity tier. For this frame size, a J-rating signifies a high interrupting capacity of 100kA at 240VAC and 65kA at 480VAC.

Are the thermal and magnetic trip settings adjustable on the HJA36150?

No. This model is equipped with a standard thermal-magnetic trip unit featuring fixed long-time and fixed instantaneous trip settings.

Does this breaker provide ground fault protection?

No. The LI trip code indicates it provides standard long-time and instantaneous protection only. If ground fault protection is required, a breaker with an LSIG or Micrologic trip unit is necessary.

Do both the line and load sides of this breaker use wire lugs?

No. The "A" in the HJA36150 catalog number indicates an I-Line connection on the line side. It utilizes integrated plug-on jaws that connect directly to the panelboard bus, while the load side features standard mechanical lugs that accept 14 AWG to 3/0 AWG wire.
