Product FAQs
6 answersWhat equipment is the KAL26125 designed to be installed in?
This legacy K-frame breaker is engineered for unit-mount applications in older Square D switchboards, motor control centers, and specific equipment enclosures. It bolts directly to the chassis and uses feed-thru lugs, meaning it will not plug onto I-Line panelboard busbars.
What is the recommended modern replacement for the KAL26125?
For system upgrades or replacing obsolete units, the modern equivalent is the Square D PowerPact H-frame series. The HGL26125 is a common replacement that provides matching amperage and higher interrupting ratings.
What are the wire size requirements for the KAL26125 terminals?
The standard feed-thru lugs accommodate both aluminum and copper conductors ranging from 4 AWG to 350 kcmil. Ensure proper torque specifications are followed during installation to prevent terminal overheating.
How does the trip unit function on the KAL26125?
It utilizes a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element, allowing electricians to fine-tune the instantaneous short-circuit response.
Is the KAL26125 suitable for direct current applications?
Yes, in addition to its AC ratings, this breaker is certified for 250VDC systems with a 10kA interrupting capacity, making it suitable for specific industrial DC control circuits.
What safety precautions should be taken before adjusting the magnetic trip settings?
Always de-energize the circuit breaker and verify that power is disconnected before modifying the adjustable magnetic trip settings. Adjustments should only be made by qualified personnel based on a proper coordination study.
