Product FAQs
7 answersWhat enclosures and panels accept the KAL26175?
This unit mount breaker is designed for use in legacy Square D enclosures, QED switchboards, and motor control centers configured for K-frame molded case circuit breakers.
What is the modern replacement for the legacy KAL series?
Schneider Electric has transitioned from the legacy K-frame to the PowerPact J-frame series for modern applications. Upgrading to a J-frame may require different mounting hardware or enclosure modifications.
Which lug kit is used for terminating conductors on this breaker?
The AL250KA mechanical lug kit is the standard terminal accessory for this frame. It accepts either copper or aluminum wire ranging from 4 AWG to 350 kcmil.
How does the adjustable magnetic trip benefit motor circuits?
The adjustable magnetic setting allows you to dial in the instantaneous trip threshold. This helps prevent nuisance tripping caused by high motor inrush currents while still providing reliable short-circuit protection.
Does the KAL26175 include ground fault or short-time protection?
No. The thermal-magnetic trip unit on this model features an LI configuration, meaning it only provides long-time (overload) and instantaneous (short-circuit) protection.
Are the line and load lugs included with this feed-thru breaker?
Yes, feed-thru K-frame breakers typically come with mechanical lugs installed on both the line and load sides, ready for standard unit mounting.
Is this breaker suitable for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity, allowing it to be used in industrial DC control and distribution circuits.
