Product FAQs
5 answersIs the KHL36175 still manufactured by Square D?
The KHL series is a legacy K-frame molded case circuit breaker. For modern upgrades or new installations, Schneider Electric recommends the PowerPact J-frame series, such as the JGL36175, which requires a frame retrofit.
What equipment is the KHL36175 designed to fit?
This unit-mount breaker is designed for use in compatible Square D enclosures, switchboards, and motor control centers. It features a feed-thru connection and is not compatible with I-Line plug-on panelboards.
What wire sizes are accepted by the lugs on the KHL36175?
The factory-installed lugs accept 4 AWG to 350 kcmil aluminum or copper wire. Ensure proper torque specifications are followed during installation.
How does the trip unit function on this breaker?
It utilizes a thermal-magnetic trip unit with long-time and instantaneous (LI) protection. The thermal element is fixed, while the magnetic trip is adjustable to allow fine-tuning of the instantaneous response.
Can the KHL36175 be used in DC power systems?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 10kA, making it suitable for specific direct current applications alongside standard AC systems.
