Product FAQs
6 answersWhich Square D distribution equipment is compatible with the HJP36040?
This unit-mount PowerPacT H-frame breaker is engineered for installation in Square D NF panelboards, QED switchboards, and Model 6 Motor Control Centers.
Is the HJP36040 suitable for high-fault commercial applications?
Yes, with a 65kAIC interrupting rating at 480VAC and 100kAIC at 240VAC, this breaker is designed for commercial and industrial systems requiring robust fault current protection.
What are the wire size limits for the HJP36040 terminals?
The terminals on this breaker accept both aluminum and copper conductors, accommodating wire sizes from 14 AWG up to a maximum of 3/0 AWG.
How does the unit-mount configuration of the HJP36040 differ from I-Line breakers?
As a unit-mount, feed-thru breaker, the HJP36040 bolts directly to a backpan or mounting plate and requires wired connections on both the line and load sides. It does not plug into an I-Line busway.
How does the thermal-magnetic trip unit in the HJP36040 operate?
The trip unit provides dual-level protection. The thermal component responds to prolonged overloads by heating a bimetallic strip, while the magnetic component reacts immediately to high-level short circuits. Both thermal and magnetic settings are fixed on this 40A model.
Can the HJP36040 be used in direct current (DC) applications?
Yes, in addition to its AC ratings, this breaker is rated for 250VDC systems with an interrupting capacity of 20kAIC.
