Product FAQs
7 answersWhat panelboards and switchboards are compatible with the HLA36090?
This breaker is designed for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection for the line side and mechanical lugs on the load side.
Can the PowerPacT HLA36090 replace older F-frame I-Line breakers?
Yes, the PowerPacT H-frame is the modern replacement for legacy 90-amp F-frame I-Line breakers, such as the FA, FH, and FC series. The H-frame offers higher interrupting ratings and supports field-installable accessories while fitting the same I-Line bus footprint.
What does the L in the HLA36090 catalog number indicate?
The L designates the interrupting rating level of the PowerPacT H-frame breaker. It indicates a high interrupting capacity of 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC.
Are the trip settings adjustable on the HLA36090?
No, this breaker features a thermal magnetic trip unit with fixed thermal and fixed magnetic settings. It provides standard long-time and instantaneous protection.
What wire sizes are accepted by the lugs on the HLA36090?
The standard factory-installed AL150HD load-side lugs accept 14 AWG to 3/0 AWG aluminum or copper conductors.
What are the torque specifications for the load-side lugs on this breaker?
For the standard AL150HD lugs, the tightening torque is 44 lbf-in (5 N.m) for 14 to 10 AWG wire, and 124 lbf-in (14 N.m) for 8 to 3/0 AWG wire.
What safety precautions should be taken before installing this I-Line breaker?
Always de-energize the I-Line panelboard or switchboard before installing or servicing the breaker. Verify that the power is off using a properly rated voltage sensing device, and wear appropriate personal protective equipment in compliance with NFPA 70E.
