Description
Designed with a factory-installed ground fault shunt trip, the Square D KH36200G provides advanced protection for commercial facilities. This 3-pole, 200A thermal-magnetic breaker operates at up to 600VAC, utilizing long-time and instantaneous (LI) functions to clear overcurrents. The unit connects into Square D I-Line panelboards and switchboards. It is officially replaced by the JJA36200, though ground fault requirements must be verified. It delivers a 35kAIC interrupt rating at 480VAC.Specifications

Product FAQs
7 answersWhat panelboards are compatible with the KH36200G circuit breaker?
This I-Line style plug-in breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a plug-on design for rapid deployment in commercial and industrial power systems.
What wire sizes and materials are accepted by the KH36200G terminals?
The factory lugs on this 200A K-Frame breaker accept 4 AWG to 350 kcmil aluminum or copper wire.
What does the G suffix indicate in the KH36200G catalog number?
The G suffix designates this as a ground fault circuit breaker. In legacy Square D K-Frame breakers, this indicates the unit is equipped with a factory-installed ground fault shunt trip for use with a compatible ground fault module (GFM) to provide equipment protection.
Is the KH36200G still actively manufactured by Square D?
The KH36200G is part of the legacy K-Frame series, which has largely been superseded by the newer PowerPact J-Frame series (such as the JGA36200 or JJA36200). However, this K-Frame unit remains a direct, drop-in replacement for existing I-Line installations requiring a 200A breaker without retrofitting the panel.
How does the KH series differ from the standard KA series K-Frame breakers?
The KH series is the High Interrupting tier of the legacy K-Frame family. It provides a higher interrupting capacity (35kA at 480V and 65kA at 240V) compared to the standard KA series, making it suitable for systems with higher available fault currents.
Can the trip settings on the KH36200G be adjusted?
Yes, this thermal-magnetic breaker features a fixed thermal trip for long-time overload protection and an adjustable magnetic trip for instantaneous short-circuit protection, allowing you to fine-tune the response to inrush currents.
Can the KH36200G be used in DC electrical systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, where it provides an interrupting capacity of 10kA.
