Built for industrial power distribution, the Square D HGA36060 is a 3-pole, 60A molded case circuit breaker from the PowerPacT H-Frame family. It provides reliable long-time and instantaneous (LI) overcurrent protection. This unit features an I-Line mounting style to install seamlessly into Square D I-Line panelboards and switchboards. It also serves as a modern replacement for legacy FA36060 and FH36060 breakers. Rated for 35kAIC at 480VAC, this current-limiting breaker is HACR rated.
Can I use the HGA36060 to replace an older FA36060 breaker?
Yes, the PowerPacT H-frame I-Line series is the direct modern replacement for legacy F-frame I-Line breakers, including the FA36060 and FH36060 models. It is designed to fit the exact same panelboards and switchboards.
What is the recommended tightening torque for the load-side lugs on this breaker?
For the standard AL150HD mechanical lugs, tighten to 44 lb-in (5 Nm) for 14 to 10 AWG wire, and 124 lb-in (14 Nm) for 8 AWG to 3/0 AWG wire.
How much bus space does this 3-pole breaker require in an I-Line panel?
As an H-frame unit, it requires 4.5 inches of mounting height on the I-Line bus stack.
Does this breaker come with mechanical lugs on both the line and load sides?
No. Because it is an I-Line plug-in style breaker, the line side features factory-installed jaw connections that mount directly onto the panelboard bus. Wire lugs are only provided on the load side.
What does the letter G in the HGA36060 part number signify?
The letter G designates the specific interrupting capacity tier within the PowerPacT H-frame family. It indicates the breaker's maximum fault-current ratings, which are 65kA at 240V, 35kA at 480V, and 18kA at 600V.
Does the HGA36060 feature a push-to-trip button for maintenance testing?
Yes, it includes an integral push-to-trip button on the front cover. This allows you to manually trip the breaker mechanism to visually verify proper operation as part of a regular preventive maintenance and safety program.
