Product FAQs

4 answers
What does the "WB" suffix indicate on the KAL36150WB circuit breaker?

The "WB" suffix designates a factory-installed walking beam mechanical interlock. This feature is designed for manual transfer switch configurations and safety applications requiring two breakers to be mechanically interlocked so only one can be closed at a time.

Is the Square D KAL36150WB still being manufactured, or is there a direct replacement?

The KAL series is a legacy K-Frame breaker and is no longer in active production. For modern panel upgrades or new installations, Schneider Electric replaces this unit with the PowerPact J-Frame series, specifically the JDL36150.

Does the KAL36150WB come with line and load lugs installed?

Yes, this unit-mount breaker includes feed-thru line and load lugs that accept 4 AWG to 350 kcmil aluminum or copper conductors.

Can I install the KAL36150WB in an I-Line panelboard?

No, the KAL36150WB is a unit-mount circuit breaker designed for standard Square D enclosures, switchboards, and motor control centers. It does not have the plug-on jaw connections required for I-Line panelboards. For I-Line applications, a KA-prefix breaker is required.
