Frequently Asked Questions
What is the Square D HDA36060U31X?
The HDA36060U31X is a 60-amp, 3-pole, 600V solid-state I-Line plug-in MCCB from Square D (Schneider Electric) used for precise adjustable overcurrent protection of branch and feeder circuits in three-phase 600V industrial electrical systems.
What does the U31X suffix mean on the HDA36060U31X?
The U31X suffix identifies the electronic trip unit rating plug configuration, which determines the minimum and maximum adjustable current pickup range of the solid-state trip. Consult Schneider Electric documentation to confirm the specific settings for U31X.
How does HDA36060U31X compare to HGA36060U31X?
Both are Square D 60A, 3-pole, 600V I-Line solid-state MCCBs with U31X rating plugs, but in different frame families: HDA is HD-frame and HGA is HG-frame. Frame differences can affect interrupting capacity, accessory options, and switchboard bus compatibility. Verify which frame your equipment requires before ordering.
