Product FAQs
7 answersWhat types of equipment are compatible with the HDM36030 breaker?
This unit-mount breaker is designed for installation in Square D switchboards, motor control centers (MCCs), industrial control panels, and dedicated PowerPacT H-Frame enclosures.
What is the difference between the HDM36030 and HDL36030 circuit breakers?
Both are 30A, 3-pole PowerPacT H-Frame breakers with identical D-class interrupting ratings. The difference is the termination style: the HDL36030 includes lugs on both the line and load sides, whereas the HDM36030 is configured with line-side lugs only.
What type of wire can be used with the line-side terminals on the HDM36030?
The factory-installed line-side lugs are dual-rated for both aluminum (Al) and copper (Cu) conductors, accepting wire sizes from 14 AWG up to 3/0 AWG.
Is the HDM36030 suitable for direct current (DC) applications?
Yes, because it utilizes a fixed thermal-magnetic trip unit, this breaker is rated for use in DC systems, offering up to a 20 kA interrupting rating at 250V DC.
How does a unit-mount breaker like the HDM36030 install into a system?
As a unit-mount (bolt-on) breaker, it is designed to be mechanically fastened directly to a backpan or mounting plate within a control panel or enclosure, rather than plugging into a modular bus system like I-Line breakers.
Can field-installable accessories be added to the HDM36030?
Yes, the PowerPacT H-Frame series supports a variety of field-installable accessories, including auxiliary switches, shunt trips, and undervoltage releases. These accessories are standardized across the H, J, and L-frame families for simplified integration.
What type of protection does the HDM36030 provide?
It features a fixed thermal-magnetic trip unit (LI), providing both long-time (thermal) protection against overloads and instantaneous (magnetic) protection against short circuits.
