Square D KH36100 - 100 A, 3-Pole Plug-In Circuit Breaker | AmpState

Square D KH36100 is a 100 A, 3-pole plug-in molded case circuit breaker engineered to deliver reliable overcurrent and short-circuit protection in panelboards and loadcenters. With a fast plug-in connection, it simplifies installation and quick replacement when maintenance is needed, minimizing downtime for service panels in residential, commercial, or light industrial settings.

What makes KH36100 stand out:

• Fast plug-in connection — effortless installation and swap-out without rewiring, helping technicians save time during panel maintenance or upgrades.
• Thermal-magnetic trip unit — delivers stable, repeatable protection across common load profiles and fault conditions, reducing nuisance trips and ensuring dependable circuit safety.
• Three-pole design (3P) — ideal for three-phase distribution and multi-branch protection in commercial and light industrial panels, while still suitable for residential applications that require 3-pole protection.
• 100 A rating — provides robust protection for feeder or branch circuits with higher continuous loads, aligned with standard panelboard configurations.
• OEM-friendly compatibility — designed to mate with matching Square D OEM load centers and panelboards, ensuring proper fit, electrical characteristics, and coordinated trip curves.
• Molded case construction — built to withstand typical panel environments in terms of robustness and durability, while preserving reliable performance over time.

Practical use cases

• Upgrading or replacing breakers in existing Square D panelboards where a 100 A, 3-pole device is required for three‑phase loads or multi‑circuit protection.
• Specifying a dependable main/feeder protection option for commercial offices, data centers, or light industrial facilities with moderate three-phase load profiles.
• Integrating into renovation projects where quick plug-in replacement minimizes panel downtime and keeps projects on schedule.
