Product FAQs
7 answersWhat equipment is the KAL26250 designed to fit?
This K-Frame breaker is engineered for unit-mount installation in legacy Square D enclosures, switchboards, and motor control centers.
What are the adjustable magnetic trip settings for the KAL26250?
The instantaneous magnetic trip on this 250A breaker is adjustable, with a low setting of 1250A and a high setting of 2500A.
What wire sizes are compatible with the KAL26250 lugs?
The standard factory lugs accept either aluminum or copper conductors ranging from 4 AWG to 350 kcmil.
What is the modern replacement for the legacy KAL26250?
The KAL series is a legacy K-Frame product. Square D now uses the PowerPact J-Frame series for modern 250A applications. Upgrading to a PowerPact breaker in an existing system often requires retrofit adapter brackets to match the original K-Frame footprint.
Can the KAL26250 be utilized in DC circuits?
Yes, in addition to its AC ratings, this breaker carries a 250VDC rating with a 10kA interrupting capacity, making it suitable for specific direct current control or distribution systems.
How does the KAL26250 mount into a system?
This is a feed-thru, unit-mount breaker. It bolts directly to a mounting pan or enclosure backplate and is hardwired, rather than plugging into a panelboard busbar.
Does the KAL26250 provide ground fault protection?
No, the KAL26250 features standard thermal-magnetic trip technology for overload and short-circuit protection. It does not include integral ground fault or arc fault capabilities.
