Built for industrial control panels and motor control centers, the HDM36060 delivers robust thermal-magnetic circuit protection. This 3-pole, 60A PowerPacT H-Frame breaker features a unit-mount design for straightforward integration into Square D switchboards and compatible enclosures. Offering a 14kAIC rating at 600VAC and 18kAIC at 480VAC, it ensures reliable long-time and instantaneous (LI) defense against overloads and short circuits. It serves as a standard-tier interrupting option.
What panels and enclosures are compatible with the HDM36060?
This PowerPacT H-Frame breaker is designed for integration into Square D switchboards, motor control centers, industrial control panels, and dedicated H-Frame enclosures.
What is the difference between the HDM36060 and HDL36060 circuit breakers?
Both are 60A, 3-pole PowerPacT H-Frame breakers with identical trip units and interrupting ratings. The difference lies in the terminations. The HDM36060 features a lug on the line side and a terminal nut on the load side, whereas the HDL36060 comes with lugs on both the line and load sides.
Can the HDM36060 be used in reverse-fed applications?
Yes, this thermal-magnetic circuit breaker is suitable for reverse-fed installations. This allows power to be supplied to either the line or load terminals without affecting the trip mechanism.
What does the D in the HDM36060 catalog number signify?
The D indicates the breaker's interrupting rating tier within the Square D PowerPacT H-Frame family. It designates a standard-tier interrupting capacity, providing up to 25 kA at 240V AC, 18 kA at 480V AC, and 14 kA at 600V AC.
How does the HDM36060 mount into a panel?
This is a unit-mount circuit breaker, meaning it bolts directly to the backpan of a panel or enclosure using mounting hardware. It is not compatible with I-Line plug-on bus systems.
Can the trip settings on the HDM36060 be adjusted?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload protection and the instantaneous short-circuit protection are factory-set and cannot be adjusted in the field.
