Product FAQs
7 answersIs the Square D KDL32100 still in active production?
No, the KDL32100 is an obsolete PowerPact K-frame circuit breaker that has been discontinued by Schneider Electric. However, it remains available for maintenance and direct replacement in existing electrical systems.
What equipment is the KDL32100 compatible with?
This unit-mount breaker is designed for installation in Square D QO 3-phase load centers, switchboards, and compatible standalone Square D enclosures.
How do you connect the wiring to the KDL32100?
This feed-thru breaker uses standard line and load side lug terminals. The lugs accept either aluminum or copper conductors ranging from 6 AWG to 350 kcmil.
How does the trip unit on the KDL32100 operate?
It features a thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal protection for overloads is fixed, while the instantaneous magnetic protection for short circuits is adjustable to suit specific load requirements.
What is the maximum fault current this breaker can safely interrupt?
The KDL32100 has a standard interrupting capacity of 25 kAIC at 240VAC, making it suitable for commercial and industrial applications requiring standard-duty fault protection.
How is the KDL32100 mounted within an enclosure?
As a unit-mount circuit breaker, it fastens directly to the backpan or mounting surface of a compatible switchboard or enclosure, rather than plugging directly onto a panelboard bus.
What frame family does the KDL32100 belong to?
It is part of the legacy Square D PowerPact K-frame family of molded case circuit breakers, which are commonly used in standard-duty commercial and industrial power systems.
