Engineered for commercial power systems, this 250A, 3-pole MCCB belongs to the Square D legacy K-Frame family. It provides robust long-time and instantaneous (LI) protection for demanding electrical networks. The unit-mount breaker integrates seamlessly into Square D switchboards and motor control centers. It serves as a predecessor to the modern PowerPacT J-Frame (JGL36250). This specific configuration includes a factory-installed 1A/1B auxiliary switch for remote status indication.Specifications

Product FAQs
6 answersWhat does the -1212 suffix indicate on the KAL36250-1212 catalog number?
The -1212 suffix designates a factory-installed 1A/1B auxiliary switch. This provides one normally open (NO) and one normally closed (NC) contact, allowing for remote status signaling and monitoring of the breaker.
What are the wire color codes for the factory-installed -1212 auxiliary switch?
For Square D legacy breakers with the -1212 auxiliary contact suffix, the standard wiring color code is yellow for the normally open (NO) contact, blue for the normally closed (NC) contact, and striped for the common wire.
What is the modern equivalent for the legacy KAL36250-1212 circuit breaker?
The KAL series is a legacy K-Frame device. For new construction, Schneider Electric has replaced this series with the PowerPact J-Frame for 250A applications. However, the KAL36250-1212 remains the correct direct replacement for existing K-Frame switchboards and motor control centers.
How does the thermal-magnetic trip unit operate on the KAL36250-1212?
It features a fixed thermal element for long-time overload protection at 250A, combined with an adjustable magnetic element for instantaneous short-circuit protection. This adjustability allows electricians to fine-tune the instantaneous trip point for better selective coordination with other protective devices.
Does the KAL36250-1212 use an I-Line plug-on connection?
No, the KAL series is a unit-mount, feed-thru circuit breaker. It uses mechanical lugs on both the line and load sides for point-to-point hardwiring. If you need an I-Line plug-on connection for a Square D panelboard, you would typically require a KA or KC series breaker instead.
Is the KAL36250-1212 suitable for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity. This makes it suitable for industrial DC control circuits or battery backup systems.
