Square D KH36175 - 175 A, 3-Pole Plug-In Circuit Breaker | AmpState

Meet the Square D KH36175: a 175A, 3-pole plug-in molded case circuit breaker crafted to deliver dependable branch circuit overcurrent and short-circuit protection for panelboards and load centers. Built to perform in demanding environments, this breaker helps keep electrical systems safe, compliant, and ready for the next load.

Why KH36175 stands out

• Fast plug-in connection for quick installation and painless replacement during maintenance or upgrades, reducing downtime and labor costs.
• Thermal-magnetic trip unit provides stable, repeatable protection by addressing both overloads (thermal) and short circuits (magnetic), so the system responds consistently under varying loads.
• Three-pole configuration ensures simultaneous disconnection of all conductors in a 3-phase system, protecting equipment like motors and compressors more effectively than single- or two-pole alternatives.
• OEM load center and panelboard compatibility designed to integrate smoothly with matching Square D gear, simplifying stocking, ordering, and field service.
• 175A rating suits higher-demand branch circuits found in commercial, office, or light industrial applications without compromising safety margins.
• Rugged molded-case construction delivers reliable endurance in crowded panel environments, resisting wear from routine maintenance and reconfigurations.

Practical use cases

Ideal for electrical installers and facilities teams looking to protect critical three-phase circuits in a variety of settings. Use KH36175 for:

• Three-phase feeds to HVAC equipment, pumps, and motors in commercial spaces.
• Branch circuits in lighting panels and small-to-mid-size panelboards in office buildings.
• Light industrial electrical rooms where dependable protection and rapid replacement are priorities.
• Maintenance upgrades or service calls where fast plug-in replacements minimize outage time.
