Schneider Electric HDA36100YP Circuit Breaker

Schneider Electric PowerPact H, 3-pole molded-case circuit breaker, model HDA36100YP, is a 100 A, 600 V AC protection device designed for distribution panels and switchgear. It uses line-side I-Line mounting and ABC phase connections to safeguard three-phase feeders, with load-side lugs sized for 14-3/0 AWG aluminum or copper conductors. The unit employs a thermal-magnetic trip mechanism and is rated for 80% continuous operation, making it suitable for standard-duty applications where continuous loads run up to 80 A in a 100 A frame. Its interrupting rating is 14 kA at 600 VAC, providing reliable fault-current interruption for typical commercial and light industrial circuits. As part of the PowerPact H family, the HDA36100YP shares common mounting footprints and compatibility with PowerPact accessories and trip-unit options, enabling straightforward replacements or upgrades within existing panels. This model is commonly employed to protect feeders feeding motors, transformers, lighting, and other power distribution loads in data centers, manufacturing facilities, and office complexes, delivering predictable, code-aligned protection and easy integration into broader protection schemes.
