Description
Built for heavy-duty industrial environments, the Square D KI36175 is a 175A, 3-pole molded case circuit breaker. It utilizes a thermal-magnetic trip unit featuring an adjustable magnetic dial from 875A to 1750A. The breaker plugs into I-Line panelboards, making installation straightforward in compatible enclosures. With a 200kAIC interrupt rating at 480VAC, it ensures superior current-limiting safety. This legacy K-Frame component is superseded by the PowerPact JRA36175.Specifications

Product FAQs
4 answersHow does the KI36175 connect to a panelboard?
The KI36175 is designed for Square D I-Line panelboards and switchboards. It utilizes a plug-on jaw connection for the line side to attach directly to the panel bus, while the load side uses standard mechanical lugs for wire termination.
What is the adjustable magnetic trip range for the KI36175?
This 175A thermal-magnetic breaker features a fixed thermal trip and an adjustable magnetic trip. The magnetic trip can be adjusted from a low setting of 875A to a high setting of 1750A.
Can the KI36175 I-Line circuit breaker be reverse fed?
No. Because of its I-Line style plug-in construction on the line side, the KI36175 is marked with specific line and load designations and is not suitable for reverse-feed applications.
What is the modern replacement for the legacy KI36175 circuit breaker?
The KI frame is an obsolete series no longer manufactured by Schneider Electric. For a 175A, 3-pole I-Line breaker with a 200kA at 480V interrupting rating, the direct modern replacement is the PowerPact J-frame, catalog number JRA36175.
