Product FAQs
6 answersWhat does the AB suffix indicate on the KH26200AB catalog number?
The AB suffix specifies the phase connection. It dictates that the line-side plug-on jaws are physically configured to connect exclusively to the A and B phases on the I-Line bus.
What is the modern replacement for the legacy KH26200AB?
The KH26200AB is a legacy K-Frame breaker. For current generation hardware upgrades, Square D replaces this exact configuration with the PowerPact J-Frame series, specifically catalog number JGA262001.
How does the I-Line mounting system work on this breaker?
The I-Line design uses a plug-on jaw mechanism on the line side that snaps directly onto the panelboard bus assembly. The load side utilizes standard mechanical lugs for wire termination, eliminating the need for line-side cabling.
What wire sizes and materials are compatible with the load lugs?
The factory-installed load lugs accept either aluminum or copper conductors ranging from 4 AWG to 350 kcmil.
Are the trip settings adjustable on the KH26200AB?
The thermal element for long-time overload protection is fixed, but the magnetic instantaneous trip function is adjustable to coordinate with specific fault current requirements.
Is the KH26200AB suitable for use with HVAC equipment?
Yes, this breaker carries an HACR rating, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
