Product FAQs
6 answersWhat is the recommended tightening torque for the load side lugs on the HLA36070?
The required torque depends on the wire gauge used. For 14 AWG to 10 AWG wire, tighten the lugs to 44.3 lb-in (5 N.m). For 8 AWG to 3/0 AWG wire, tighten to 123.9 lb-in (14 N.m).
Can the PowerPact H-frame HLA36070 replace older F-frame I-Line breakers?
Yes, the PowerPact H-frame is the direct modern replacement for legacy 70-amp F-frame I-Line breakers, such as the FAL36070 or FHL36070. It installs into the same Square D I-Line panelboards and switchboards.
What does the L in the HLA36070 catalog number signify?
The L indicates the interrupting rating tier within the PowerPact H-frame family. It signifies a high interrupting capacity of 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC.
How does the I-Line connection type work on this breaker?
The breaker features a plug-on line side that snaps directly onto the busbar of an I-Line panelboard. The load side utilizes standard mechanical lugs for wire termination, allowing for fast and secure installation without line-side wiring.
Is the HLA36070 circuit breaker suitable for reverse feeding?
Yes, this thermal-magnetic PowerPact H-frame breaker is suitable for reverse-fed applications. Always ensure the installation complies with your local electrical codes and panelboard labeling.
Does this breaker feature a manual trip indicator?
Yes, it includes a Visi-Trip indicator and an integral push-to-trip button on the front cover. This allows electricians to manually test the mechanical tripping mechanism and easily identify a tripped breaker in the panel.
