Description
Designed to minimize thermal stress, the Square D IKL34225 is a 225A current-limiting MCCB. It rapidly clears severe faults to protect sensitive downstream equipment. This unit-mount breaker installs into Square D panelboards. It serves as a replacement for aging K-Frame installations and is replaced by the JRL36225. With a 200kAIC rating at 480VAC, it provides robust high-interrupting capacity. The thermal-magnetic trip unit ensures reliable short-circuit protection.Specifications

Product FAQs
7 answersWhat is the modern replacement for the Square D IKL34225?
The IKL34225 is a legacy K-Frame circuit breaker. For new installations or panel upgrades, it is typically replaced by the modern PowerPact J-Frame series, specifically the JRL36225.
Can the IKL34225 be installed in an I-Line panelboard?
No, the IKL34225 is a unit-mount circuit breaker designed with feed-thru lugs. It does not feature the plug-on jaw connections required for Square D I-Line panelboards.
What type of enclosures or panels is the IKL34225 compatible with?
This unit-mount breaker is designed for installation in compatible Square D panelboards and switchboards that are configured to accept legacy K-Frame components.
What does the current-limiting feature of the IKL34225 mean for my system?
As a current-limiting breaker with a 200kAIC rating at 480V, it rapidly clears severe electrical faults. This minimizes let-through energy, reducing thermal and magnetic stress to protect sensitive downstream equipment.
Are the trip settings on the IKL34225 adjustable?
This breaker features 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.
How are conductors terminated on the IKL34225?
This breaker utilizes a feed-thru connection type with factory-installed lugs. These lugs are rated for both aluminum and copper conductors ranging from 4 AWG to 350 kcmil, providing flexibility for various field wiring requirements.
Is the IKL34225 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is certified for safe use with heating, air conditioning, and refrigeration equipment.
