Product FAQs

6 answers
What equipment is the Square D KIL26150 designed to mount in?

This legacy K-frame breaker is engineered for installation in Square D enclosures, switchboards, and motor control centers.

What is the modern replacement for the KIL26150 circuit breaker?

For new installations or upgrades, the legacy KIL26150 is replaced by the PowerPact J-frame series, specifically catalog number JRL26150.

What wire sizes and materials are compatible with the terminals on this breaker?

The factory-installed line and load lugs accept both aluminum and copper conductors ranging from 4 AWG to 350 kcmil.

Are the trip settings adjustable on the KIL26150?

The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit response.

Does the KIL26150 provide current-limiting protection?

Yes, the KIL frame is a current-limiting molded case circuit breaker designed to restrict let-through fault current, offering a high interrupting capacity of 200kA at 480V.

What does the unit mount and feed-thru configuration mean for installation?

As a unit mount, feed-thru breaker, it is designed to be individually mounted and wired directly via the line and load lugs, rather than plugging into a distribution busbar.
