Engineered for commercial applications, the Square D HLA36035 is a 3-pole, 35A MCCB. It delivers dependable thermal-magnetic protection with fixed LI trip functions. Designed for Square D I-Line panelboards and switchboards, it utilizes a plug-on mounting system for efficient installation. It includes load-side lugs for 14-3/0 AWG wire. Offering a 100 kAIC rating at 480VAC, this current-limiting device provides superior short-circuit protection.
What panelboards accept the HLA36035 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line-side connection and mechanical lugs on the load side.
How does the HLA36035 connect to the panelboard bus?
The breaker plugs directly into the I-Line bus stack on the line side using integrated jaws. The load side utilizes standard mechanical lugs for wire connections.
What is the required tightening torque for the load lugs?
The standard AL150HD load lugs require a tightening torque of 44.25 lb-in (5 N.m) for 14 AWG to 3/0 AWG wire.
What does the L in the HLA36035 catalog number signify?
The L designates the interrupting rating tier of the PowerPacT H-frame series. It indicates a high interrupting capacity of 100kA at 480VAC.
Can this breaker replace legacy Square D F-frame I-Line breakers?
Yes, PowerPacT H-frame I-Line breakers are the direct modern replacements for older F-frame I-Line models, such as the FAL36035 and FHL36035.
What type of trip unit is installed in the HLA36035?
It is equipped with a fixed thermal-magnetic trip unit. This provides long-time thermal protection for overloads and instantaneous magnetic protection for short circuits.
Can the HLA36035 be reverse fed?
No. Due to the I-Line plug-on jaw design on the line side, this breaker is restricted to standard line-to-load power flow and cannot be reverse fed.
