Product FAQs
7 answersWhat does the U43A suffix indicate on the PGL36060U43A circuit breaker?
The U43A suffix specifies that the breaker is equipped with a Micrologic 5.0 A electronic trip unit. This provides Long-Time, Short-Time, and Instantaneous (LSI) trip functions, along with an integrated ammeter for real-time current monitoring.
Is the PGL36060U43A a standard or 100 percent rated circuit breaker?
This breaker is standard 80 percent rated for continuous current.
Does the PGL36060U43A mount directly to an I-Line panelboard bus?
No, the L in the PGL prefix indicates it is a unit-mount breaker with mechanical lugs on both the line and load sides. For an I-Line plug-on connection, a PGA-prefix breaker is required.
Can the Micrologic trip unit on this P-Frame breaker be swapped in the field?
Yes, PowerPacT P-Frame breakers equipped with Micrologic trip units allow the trip unit to be interchanged in the field. This provides flexibility to upgrade functionality, such as adding advanced power metering or communication capabilities, without replacing the entire breaker frame.
Does this breaker provide ground fault protection?
No, the Micrologic 5.0 A trip unit provides Long-Time, Short-Time, and Instantaneous (LSI) protection only. Equipment ground fault protection requires a Micrologic 6.0 trip unit.
Does the PGL36060U43A support Zone-Selective Interlocking (ZSI)?
Yes, the Micrologic 5.0 A trip unit includes short-time Zone-Selective Interlocking (ZSI) capability. This feature allows the breaker to communicate with downstream devices to improve system coordination and reduce fault clearing times.
Can a motor operator be added in the field to the PGL36060U43A for remote operation?
No, electrically operated P-Frame circuit breakers require a factory-installed motor assembly. Motor-operated versions are denoted by an M suffix in the catalog number and cannot be retrofitted in the field to a standard manually operated breaker.
