Frequently Asked Questions
What is the Square D HDA36100 used for?
The Square D HDA36100 is a 100-amp, 3-pole, 600V thermal magnetic I-Line plug-in MCCB used to protect feeder and branch circuits in commercial and industrial three-phase 600V electrical distribution systems.
Is the HDA36100 compatible with Square D I-Line panelboards?
Yes. The HDA36100 features I-Line plug-in mounting, making it directly compatible with Square D I-Line panelboards and switchboards rated for HD-frame breakers. Verify bus ampacity and frame compatibility before installation.
What does the thermal magnetic trip type mean for the HDA36100?
Thermal magnetic means the breaker uses a bimetallic strip for overload (time-delay) protection and an electromagnetic mechanism for instantaneous short-circuit interruption, providing dual-mode overcurrent protection in a single device.
