Product FAQs
6 answersIs the Square D KAL26200WB still in active production?
The KAL series is a legacy K-frame molded case circuit breaker. For new installations, Square D has transitioned to the PowerPact J-frame series. However, KAL breakers are still widely sourced as direct replacements for maintaining existing enclosures and switchboards.
What does the "WB" suffix indicate on the KAL26200WB?
The "WB" suffix designates that the breaker is factory-prepped for use with a walking beam mechanical interlock system. Implementing the interlock requires two breakers with the WB suffix, a walking beam assembly, and a compatible mounting pan.
Can I install the KAL26200WB on an I-Line panelboard bus?
No, this is a unit mount, feed-thru circuit breaker. It is designed to be hard-wired with lugs and mounted directly to the backpan in Square D enclosures or switchboards, rather than plugging into an I-Line distribution bus.
How does the adjustable magnetic trip function work on this K-frame breaker?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element. The adjustable magnetic dial allows electricians to set the instantaneous short-circuit trip threshold to coordinate with downstream devices or specific load inrush currents.
Is the KAL26200WB suitable for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for use in DC applications up to 250VDC, providing a 10kA interrupting capacity for DC circuits.
What are the lug wire size requirements for the KAL26200WB?
The standard feed-thru lugs on this breaker are designed to accept wire gauges ranging from 4 AWG up to 350 kcmil, and they are compatible with both aluminum and copper conductors.
