Product FAQs
7 answersWhat does the 1021 suffix mean on the KAL361751021?
The 1021 suffix indicates that this circuit breaker includes a factory-installed 120/240VAC shunt trip. This allows the breaker to be opened remotely by applying a voltage signal to the shunt trip coil.
What equipment is compatible with the KAL361751021 breaker?
This unit-mount K-frame breaker is designed for installation in Square D enclosures, switchboards, and motor control centers. Because it has a feed-thru connection with lugs on both ends, it is not compatible with I-Line panelboards.
Can the KAL361751021 be used in direct current systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in 250VDC applications with a 10kA interrupting capacity.
What wire sizes and materials are supported by the KAL361751021 lugs?
The factory-installed line and load lugs accept both aluminum and copper conductors ranging from 4 AWG to 350 kcmil.
What is the modern replacement for the legacy KAL361751021?
While the KAL361751021 is an exact fit for existing legacy K-frame installations, Square D has replaced the K-frame series with the PowerPacT J-frame for new installations and panel designs.
Are the trip settings adjustable on the KAL361751021?
The thermal (long-time) protection is fixed at 175 amps, but the magnetic (instantaneous) trip function is adjustable to allow coordination with other protective devices in your system.
Does the KAL361751021 provide a visual indication when it trips?
Yes, the operating handle will move to a center position between ON and OFF to provide a clear visual indication that the breaker has tripped.
