Product FAQs

5 answers
What does the YP suffix indicate on the QBL32100YP circuit breaker?

The YP suffix denotes a factory-installed handle padlock attachment. This device allows the breaker handle to be securely locked in either the ON or OFF position for lockout and tagout safety procedures.

Can the QBL32100YP replace older Square D Q2 series circuit breakers?

Yes, PowerPacT Q-frame circuit breakers are direct replacements for legacy Q2 Series devices, including the Q23100. They are designed to fit into existing Q2 enclosures, switchboards, and control panels.

Does the QBL32100YP come with lugs installed?

Yes, this feed-thru breaker includes factory-installed box lugs on both the line and load sides. The terminals accept 4 AWG to 300 kcmil aluminum or copper conductors.

Is the QBL32100YP compatible with I-Line panelboards?

No, this is a unit-mount circuit breaker designed for cabled applications or individual enclosures. It does not have the plug-on jaw configuration required for I-Line group-mounted panelboards.

What does the B in the QBL frame designation represent?

In the Square D PowerPacT Q-frame nomenclature, the B indicates the interrupting rating. A QBL breaker provides a 10 kA interrupting capacity at 240VAC, whereas QD, QG, and QJ frames offer higher fault current ratings.
