HDL36125 - 125 Amp Circuit Breaker

HDL36125 - 125 Amp Circuit Breaker

The HDL36125 is engineered specifically to protect electrical systems from overloads and short circuits, delivering dependable service in demanding commercial, industrial and large-scale residential settings. With a continuous current rating of 125 A and the capability to interrupt up to 14 kA at 600 V AC, this breaker offers serious protection when it matters most. It’s part of the PowerPacT H-Frame lineup and uses thermal-magnetic trip technology to respond quickly while staying stable under normal load. The design allows flexible installation via a snap-in terminal that switches between bus-bar and lug configurations—reducing installation time and inventory complexity. Built with both performance and sustainability in mind, the unit meets stringent environmental requirements (RoHS/REACh) and carries the Green Premium™ label. Rugged from –25 °C to +70 °C, and certified to UL, CSA, NOM and IEC standards, the HDL36125 brings peace of mind to the professionals who depend on it.

Key Features and Benefits

• Thermal-magnetic sensing: In each pole ensures precise protection against both overloads and short circuits.
• Snap-in terminal design: Supports quick change-over between bus-bar and lug installations, reducing downtime and simplifying inventory.
• Certified breaking capacities:
  • 14 kA at 600 V AC
  • 25 kA at 240 V AC
  • 18 kA at 480 V AC
  • 20 kA at 250 V DC
• Continuous current capacity: 125 A (80% rating) makes it a reliable choice for heavier duty distribution circuits.
