Product FAQs
7 answers
What equipment is the Square D PGL36080U33A designed to fit?
This 800A PowerPacT P-frame circuit breaker is compatible with Square D QED switchboards, Model 6 motor control centers, and standalone enclosures.
What does the U33A suffix indicate on the PGL36080U33A catalog number?
The U33A suffix signifies that the breaker is equipped with a Micrologic 5.0 electronic trip unit. This provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) trip functions for precise system coordination.
What wire sizes are accepted by the factory lugs on this breaker?
The included lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
How is the PGL36080U33A mounted in a panel?
This is a unit-mount, feed-thru circuit breaker. It is designed to be bolted directly to the mounting surface or busbar, unlike plug-on I-Line variants.
Can the trip unit on the PGL36080U33A be swapped or upgraded in the field?
Yes, PowerPacT P-frame circuit breakers feature interchangeable Micrologic trip units. This allows you to upgrade the trip unit in the field if your protection, metering, or communication requirements change.
Does the Micrologic 5.0 trip unit support Zone Selective Interlocking (ZSI)?
Yes, the Micrologic 5.0 trip unit included with this breaker supports short-time Zone Selective Interlocking (ZSI). This feature helps minimize equipment damage by clearing short circuits faster when coordinated with downstream breakers.
Does this P-frame breaker include a manual testing feature?
Yes, it includes an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the tripping mechanism during routine maintenance.
