Built for demanding electrical distribution networks, the Square D HGL36035 is a 3-pole, 35A molded case circuit breaker from the PowerPacT H-Frame family. It mounts into industrial control panels and switchboards using included line and load lugs. The breaker delivers thermal-magnetic protection with fixed LI functions, ensuring safety across commercial environments. With a 35kAIC rating at 480V, it features a Visi-Trip indicator for rapid fault identification.
What types of enclosures and panels are compatible with the HGL36035?
This PowerPacT H-Frame breaker is designed for use in industrial control panels, switchboards, and dedicated PowerPacT H-Frame enclosures. It features a unit-mount, feed-thru design rather than a plug-on connection.
Will the HGL36035 fit into a Square D I-Line panelboard?
No, the HGL36035 is a unit-mount breaker with feed-thru lug connections. For an I-Line panelboard, you need an I-Line version of the H-Frame breaker, which typically features an A in the third position of the catalog number instead of an L.
What wire sizes are accepted by the standard lugs on the HGL36035?
The factory-installed lugs accept wire gauges from 14 AWG up to 3/0 AWG. They are rated for both aluminum and copper conductors.
Is the HGL36035 rated for direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for DC systems. It provides an interrupting capacity of 20kA at both 250VDC and 500VDC.
Can the trip settings be adjusted on the HGL36035?
No, this breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. It provides standard long-time and instantaneous (LI) protection without adjustable dials.
How does the HGL36035 compare to the HDL36035?
The HGL36035 has a higher interrupting capacity (G-tier) than the HDL36035 (D-tier). The HGL provides 35kA at 480VAC, while the HDL provides 25kA at 480VAC. Both share the same physical dimensions, mounting style, and 35-amp rating.
