Description
Part of the legacy K-Frame series, the Square D IK34200 is a 200A, 3-pole molded case circuit breaker built for industrial applications. It features thermal-magnetic protection with an adjustable magnetic trip. This unit mounts into Square D I-Line panelboards. As a legacy component, it serves as a replacement for older installations and is superseded by the JRA36200. Operating as an I-Limiter, it delivers a 200kAIC rating at 480V, reducing let-through energy during severe faults.Specifications

Product FAQs
7 answersHow much vertical mounting space does the IK34200 require in a panelboard?
As a 3-pole K-Frame breaker, it requires 4.5 inches of vertical mounting space on the I-Line bus stack.
Is the IK34200 still actively manufactured?
No, the IK frame is a legacy component that has been discontinued by Schneider Electric. It is typically superseded by the PowerPact J-Frame series, such as the JRA36200, which maintains the same 200kAIC interrupting capacity and I-Line mounting.
What is the benefit of the current limiting feature on this breaker?
As a Square D I-Limiter, this breaker is engineered to clear high-magnitude short circuits in less than half a cycle. This drastically reduces the peak let-through current and thermal energy, protecting sensitive downstream equipment without the need for external fuses.
How is the line-side connection made on this breaker?
The breaker utilizes the Square D I-Line plug-on design. The line-side jaws ratchet directly onto the panelboard bus stack and are secured with a single retaining screw, eliminating the need to torque individual line-side cables or bus connections.
Can this breaker be installed in an NF or NQ series panelboard?
No. The plug-on jaw mechanism is specifically designed for Square D I-Line panelboards and switchboards. It is not compatible with NF, NQ, or QO series enclosures.
How does the adjustable magnetic trip work on the IK34200?
While the long-time thermal overload protection is fixed at 200 amps, the instantaneous magnetic trip threshold can be adjusted by the user. This allows electricians to fine-tune the short-circuit response to coordinate with other protective devices in the system or accommodate specific motor inrush currents.
Does the IK34200 provide equipment ground fault protection?
No. This model is equipped with a standard thermal-magnetic trip unit featuring long-time and instantaneous (LI) functions. It does not include the ground fault (G) protection required for certain service entrance applications.
