Engineered for commercial and industrial applications, the HDP36060 is a 60A, 3-pole molded case circuit breaker designed by Square D. It provides robust thermal-magnetic protection with long-time and instantaneous (LI) trip functions. This unit mount breaker installs into industrial control panels and switchboards. It features standard line and load side lugs, accepting 14-3/0 AWG wire. Rated for 14kAIC at 600VAC, it is HACR rated, current limiting, and includes a Visi-Trip indicator.
What type of mounting does the Square D HDP36060 require?
The HDP36060 is a unit-mount, bolt-on circuit breaker. It features lugs on both the line and load sides, making it suitable for industrial control panels, switchboards, and standalone enclosures. It cannot be used in I-Line panelboards.
What replacement lug kit is used for the HDP36060 breaker?
The standard replacement mechanical lug kit is catalog number AL150HD. These lugs accept 14 AWG to 3/0 AWG aluminum or copper wire.
Are copper-only lugs available for this 60A H-Frame breaker?
Yes. If your installation requires copper-only connections, you can use the CU150HD mechanical lug kit. The CU150HD accommodates 14 AWG to 2/0 AWG copper wire.
What do the letters in the HDP36060 catalog number mean?
"HD" indicates a PowerPacT H-Frame breaker with a D-class interrupting rating. The "P" designates it as a unit-mount breaker with lugs on both ends. The "36060" specifies a 3-pole, 600VAC maximum, 60A breaker.
Can the HDP36060 be used in DC control circuits?
Yes, this breaker is rated for use in direct current applications up to 250VDC, where it provides a 20kA interrupting rating.
How does the HDP36060 differ from the HDA36060?
The HDP36060 is a unit-mount breaker with lugs on both the line and load sides. The HDA36060 is an I-Line breaker that features a plug-on bracket on the line side for use exclusively in Square D I-Line panelboards and switchboards.
Does the HDP36060 include a push-to-trip feature?
Yes, all PowerPacT H-Frame circuit breakers include an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the trip mechanism.
