Designed to limit let-through currents, the Square D HDA260602 is a 60A, 2-pole PowerPacT H-Frame MCCB. It utilizes thermal-magnetic technology to deliver LI protection. Equipped with a phase AC connection, this unit mounts into Square D I-Line panelboards and switchboards. It provides a seamless replacement for legacy FA26060AC breakers. Rated for 18 kAIC at 480VAC, it includes a Visi-Trip indicator for rapid fault identification and is HACR rated for HVAC applications.
What does the 2 at the end of the HDA260602 catalog number indicate?
The 2 indicates the breaker is factory-configured for an AC phase connection on the I-Line bus. Other suffixes are used for different phase arrangements, such as 1 for AB or 4 for BC.
Which panelboards are compatible with the HDA260602 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line side connection that mounts directly to the I-Line bus stack. It will not fit standard NQ, NF, or QO load centers.
How is the load side wired on the HDA260602?
The breaker features factory-installed mechanical lugs on the load side that accept 14 AWG to 3/0 AWG aluminum or copper conductors. The line side utilizes the I-Line plug-on jaw connection.
Can the HDA260602 replace older FA series breakers?
Yes, this PowerPacT H-Frame breaker is the direct modern replacement for the legacy FA26060AC circuit breaker. It fits the same I-Line bus space and provides the identical AC phase connection.
What does the D in the HDA prefix signify?
The D designates the interrupting rating tier for this PowerPacT H-Frame breaker. It provides 25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC.
How does the I-Line connection secure to the bus?
The breaker uses a plug-on jaw connector for the line side that ratchets firmly onto the I-Line bus stack. It is then secured in place with a mounting bracket screw, eliminating the need for separate bus connectors.
