Product FAQs
6 answersWhat size wire can be used with the standard lugs on this breaker?
The HJL36125 comes standard with AL150HD lugs, which accept 14 AWG to 3/0 AWG aluminum or copper wire.
Is the HJL36125 suitable for reverse-fed applications?
Yes. Because this is a thermal-magnetic PowerPacT H-frame circuit breaker, it can be reverse fed, allowing power to be supplied to either the line or load terminals.
What is the difference between the HJL36125 and the HJA36125 circuit breakers?
The HJL36125 is a unit-mounted circuit breaker equipped with feed-thru lugs on both sides. The HJA36125 shares the same electrical specifications but features an I-Line style plug-in connection on the line side for use in I-Line panelboards.
What does the J in the HJL catalog number indicate?
In Square D PowerPacT nomenclature, the J specifies the interrupting capacity tier. For this frame size, it indicates maximum fault current interruption ratings of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
What is the purpose of the push-to-trip button on the front cover?
The push-to-trip button allows you to manually trip the circuit breaker. This is a safety feature used to verify that the internal mechanical tripping mechanism is operating correctly during routine maintenance.
Which panels or enclosures are compatible with the HJL36125?
This breaker is designed for unit-mount installation in industrial control panels, switchboards, motor control centers, and dedicated PowerPacT H-Frame enclosures. It will not fit in standard residential QO or Homeline load centers.
