Description
Part of the legacy K-Frame series, this 200A thermal-magnetic MCCB provides reliable overcurrent protection for industrial power systems. The unit mount configuration installs into Square D enclosures and switchboards. It serves as a replacement for older installations, though it is replaced by the JGL36200 for new builds. This model includes a factory-installed 24VDC shunt trip for remote operation. It delivers a 65kA interrupting capacity at 240VAC and features an adjustable magnetic trip.Specifications

Product FAQs
6 answersWhat does the -1027 suffix mean on the KHL36200-1027 circuit breaker?
The -1027 suffix indicates that this breaker includes a factory-installed shunt trip with a 24V DC coil. This allows the breaker to be tripped remotely for emergency shutdown, fire alarm interlocks, or control circuit integration.
Can I use the KHL36200-1027 to replace a standard KHL36200?
While they share the same 200A rating, K-frame footprint, and 35kAIC at 480V capacity, the KHL36200-1027 includes a 24V DC shunt trip. It should only be used if your control circuit requires this specific remote trip functionality.
What equipment is the KHL36200-1027 designed to fit?
This unit-mount K-frame breaker is compatible with Square D enclosures, switchboards, and motor control centers configured for feed-thru connections.
What wire sizes are supported by the terminals on this breaker?
The factory-installed line and load side lugs accept either aluminum or copper wire ranging from 4 AWG to 350 kcmil.
How does the trip unit operate on the KHL36200-1027?
It utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Is this K-frame breaker rated for DC voltage systems?
Yes, in addition to its AC ratings, the KHL36200-1027 is rated for use on 250V DC systems with a 10kA interrupting capacity.
