Product FAQs
8 answersWhat does the 1212 suffix mean on the Square D KAL361501212?
The 1212 suffix indicates the breaker includes a factory-installed 1A/1B auxiliary switch. This allows for remote status signaling to indicate whether the breaker is open or closed.
Is the KAL361501212 still in active production?
The Square D KAL series is a legacy K-Frame product. While exact replacements are used to maintain existing switchboards and motor control centers, new builds typically utilize the modern PowerPact J-Frame series, such as the JGL36150.
What type of lugs are included with the KAL361501212?
This breaker typically includes AL250KA line and load lugs, which are rated for both aluminum and copper conductors ranging from 4 AWG to 350 kcmil.
Can I install the KAL361501212 in an I-Line panelboard?
No. The KAL361501212 is a unit-mount, feed-thru breaker designed for individual enclosures, switchboards, and motor control centers. It does not have the plug-on jaw connections required for Square D I-Line panelboards.
How does the trip unit function on the KAL361501212?
It uses a thermal-magnetic trip unit with a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection.
Can the KAL361501212 be used in DC applications?
Yes. The KAL361501212 is rated for up to 250VDC with an interrupting capacity of 10kA, making it suitable for compatible direct current systems.
What is the maximum frame rating for the KAL361501212?
The KAL361501212 is built on the Square D K-Frame, which has a maximum physical frame rating of 250 amps, though this specific unit is calibrated for a 150-amp continuous load.
What is the magnetic trip adjustment range for the KAL361501212?
The adjustable magnetic trip settings for this 150-amp breaker range from a low of 750 amps to a high of 1500 amps.
