Product FAQs
6 answersWhat does the 1212 suffix mean on the KAL362501212 circuit breaker?
The 1212 suffix indicates that this breaker includes a factory-installed 1A/1B auxiliary switch, which allows for remote signaling and tracking of the breaker status.
What are the wire colors for the 1212 auxiliary switch contacts?
For the factory-installed 1212 auxiliary switch, the normally open (NO) contact uses the yellow wire, the normally closed (NC) contact uses the blue wire, and the common connection uses the striped wire.
Is the Square D KAL362501212 obsolete, and what is the modern replacement?
Yes, the legacy K-Frame series has been discontinued. The modern upgrade for a 250A, 3-pole KAL breaker is the Square D PowerPacT J-Frame series, such as the JGL36250 or JDL36250, depending on your specific interrupting rating requirements.
What enclosures and panels is the KAL362501212 compatible with?
This unit-mount K-Frame breaker is designed to fit into legacy Square D enclosures, QED switchboards, and motor control centers that accept feed-thru lug configurations.
How does the trip unit on the KAL362501212 operate?
It utilizes a thermal-magnetic trip unit where the thermal element provides fixed long-time overcurrent protection, and the magnetic element can be adjusted in the field to fine-tune instantaneous short-circuit protection.
How is the KAL362501212 installed in a system?
This is a unit-mount, feed-thru circuit breaker. It does not plug onto a busbar; instead, it is hardwired using mechanical lugs on both the line and load sides and is secured directly to the enclosure or backpan.
