Product FAQs
7 answersWhat is the modern replacement for the legacy Square D KAL36250?
The KAL36250 is part of the legacy K-frame series. Its official modern replacement in the Square D lineup is the PowerPacT JGL36250 molded case circuit breaker.
Can I install the KAL36250 in a Square D I-Line panelboard?
No. The KAL36250 features a unit-mount, feed-thru design meant for QED switchboards, motor control centers, and individual enclosures. I-Line plug-on panelboards require the corresponding I-Line version, such as the KA36250.
What lug kit is equipped on the KAL36250, and what are its wire capacities?
This circuit breaker uses the AL250KA standard lug kit. These factory lugs accommodate both aluminum and copper conductors ranging from 4 AWG to 350 kcmil.
What is the adjustment range for the magnetic trip on this 250A breaker?
The instantaneous magnetic trip element on the KAL36250 is front-adjustable. It can be set from a Low threshold of 1250A up to a High threshold of 2500A.
Are there higher interrupting capacity variants of this K-frame breaker available?
Yes. The KAL36250 has a standard interrupting capacity of 25kA at 480V. If your system requires a higher fault current rating within the exact same physical footprint, you can cross-reference to the high-interrupting KHL36250 or the extra-high-interrupting KCL36250.
How does the LI trip unit on the KAL36250 operate?
The LI designation means the breaker provides Long-Time (L) and Instantaneous (I) protection. It utilizes thermal-magnetic technology featuring a fixed thermal element for continuous overload protection and an adjustable magnetic element for short-circuit protection.
Can the KAL36250 be utilized in direct current (DC) systems?
Yes, this breaker is rated for 250VDC applications with a 10kA interrupting capacity. When using multi-pole AC/DC breakers in ungrounded DC systems, specific series wiring configurations are often required, so always verify the manufacturer DC wiring guidelines prior to installation.
