Product FAQs

8 answers
How does the HGA36050 connect to the panelboard?

This breaker features an I-Line plug-on connection. It mounts directly onto the panel busbars on the line side and utilizes standard mechanical lugs on the load side for wire termination.

What type of enclosures accept this circuit breaker?

The HGA36050 is designed exclusively for use in Square D I-Line panelboards and I-Line switchboards. It will not mount in standard unit-mount panels, QO load centers, or NQ panelboards.

What does the G in the HGA36050 part number indicate?

The G designates the interrupting rating tier within the PowerPacT H-Frame family. It specifies a breaking capacity of 65 kA at 240VAC, 35 kA at 480VAC, and 18 kA at 600VAC.

Can the HGA36050 be used to replace legacy Square D breakers?

Yes, this PowerPacT H-Frame breaker serves as a direct, modern replacement for obsolete FA36050 and FH36050 I-Line circuit breakers.

How does the trip unit on the HGA36050 operate?

It utilizes a fixed thermal-magnetic trip unit with Long-Time and Instantaneous functions. The thermal mechanism protects against sustained overloads, while the magnetic mechanism trips instantly during high-level short circuits.

Does the HGA36050 include lugs for wire termination?

Yes, it comes equipped with factory-installed load lugs that accept 14 AWG to 3/0 AWG aluminum or copper wire. The line side uses the I-Line plug-on jaw connection, requiring no line-side wiring.

Is the HGA36050 rated for 100% continuous operation?

No, this is a standard 80% rated circuit breaker. According to standard electrical codes, continuous loads lasting three hours or more must not exceed 80% of its 50-amp nominal rating, which is 40 amps.

Does this breaker feature a mechanical trip test?

Yes, PowerPacT H-Frame breakers include a push-to-trip button on the front face. This allows maintenance personnel and panel builders to manually trip the breaker and verify proper mechanical operation of the toggle mechanism.
