The Square D HDA36100UR 100A 3-Pole 600 V Circuit Breaker is engineered to deliver reliable overcurrent protection for demanding three-phase power systems. With a 100 amp rating and a 3-pole configuration, this unit is designed to safely shield large feeders and motors in commercial and light industrial environments. Identified by part number HDA36100UR, it’s built to fit Square D panels and compatible bus configurations, making it a precise, drop-in replacement for compatible installations.

  • Three-pole design provides balanced protection across all three phases in 3-phase power systems.
  • Current rating: 100 A protects feeders and circuits against overloads in demanding loads such as motors and HVAC equipment.
  • Voltage rating: 600 V suitable for industrial distribution and higher-voltage applications within safe, code-compliant limits.
  • Part Number: HDA36100UR ensures precise replacement compatibility with Square D panels and related configurations.
  • Durable, purpose-built construction designed for dependable performance in professional electrical environments where reliable protection matters most.

Use cases and scenarios

Ideal for protecting three-phase motor feeds, large lighting and power circuits, or distribution panels in commercial facilities, warehouses, and light industrial settings. This breaker serves as a trusted replacement in systems that require a 100A, 3-pole device rated for up to 600V, ensuring consistent performance and protection where downtime or equipment damage would be costly.

Key considerations for installation and compatibility

  • Verify panel compatibility: this unit is designed for Square D panels that support HDA-type breakers and 3-pole, 600V configurations.
  • Confirm circuit requirements: ensure your installation calls for a 100 A protection device in a 3-phase, 600 V system.
  • Follow safety and code guidelines: disconnect power before servicing, and replace only with the specified part number or an approved equivalent for your panel.
