Product FAQs
7 answersWhat does the "-1352" suffix indicate on the KAL36225-1352 part number?
The "-1352" suffix designates that the circuit breaker includes a factory-installed auxiliary switch for remote status indication or control circuit integration.
Where can the KAL36225-1352 breaker be installed?
This unit-mount K-frame breaker is compatible with Square D switchboards, motor control centers, and standalone enclosures designed to accept feed-thru MCCBs. It is not compatible with I-Line panelboards.
How does the thermal-magnetic trip unit operate on this K-frame breaker?
The trip unit provides long-time (L) thermal protection for overloads, which is fixed, and instantaneous (I) magnetic protection for short circuits, which is adjustable to suit specific load requirements.
What is the difference between the frame size and the amperage rating on this breaker?
The KAL36225-1352 is built on a 250A K-frame, which is the maximum physical capacity of the breaker housing, but it is factory-calibrated with a specific continuous current trip rating of 225A.
What safety precautions should be taken before adjusting the magnetic trip settings?
Always ensure the circuit breaker is de-energized and properly locked out before making any adjustments to the instantaneous magnetic trip dials to prevent arc flash hazards or accidental contact with live components.
Does this breaker require a specific mounting hardware kit?
As a unit-mount (feed-thru) breaker, it bolts directly to the backpan of an enclosure or switchboard. Depending on the specific panel design, you may need a dedicated Square D mounting bracket or strap kit.
What is the modern PowerPact replacement for the legacy KAL36225-1352?
The KAL series is a legacy K-frame breaker. When upgrading older infrastructure, Schneider Electric replaces this series with the PowerPact J-frame (such as the JGL36225). Since the "-1352" suffix indicates an auxiliary switch, ensure your replacement also includes an auxiliary contact accessory.
