Equipped with an interchangeable Micrologic 3.0A electronic trip unit, it provides adjustable LI protection with an ammeter.
What panelboards are compatible with the PGA36060U41A circuit breaker?
This breaker features an I-Line style plug-in connection, making it compatible with Square D I-Line panelboards and switchboards. It mounts directly onto the bus stack without requiring separate mounting brackets.
What does the U41A suffix indicate on this PowerPacT breaker?
The U41A suffix signifies that the breaker is equipped with a Micrologic 3.0A (Ammeter) electronic trip unit. This provides adjustable Long-Time and Instantaneous (LI) trip functions, along with integrated current metering.
Is the PGA36060U41A built on a 600A or 1200A frame?
It is built on the 1200A PowerPacT P-Frame architecture but is factory-equipped with a 600A sensor. The maximum continuous current is limited to 600 amps.
Can the trip unit on the PGA36060U41A be swapped in the field?
Yes. PowerPacT P-Frame breakers with Micrologic trip units feature interchangeable trip units. You can upgrade to a different Micrologic unit, such as a 5.0A or 6.0A, in the field without replacing the entire breaker.
What size wire is accepted by the standard lugs on the PGA36060U41A?
The standard factory lugs accept three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
What does the G in the PGA36060U41A catalog number represent?
The G indicates the interrupting rating tier for this PowerPacT P-Frame breaker. It provides a short circuit current rating of 65kAIC at 240VAC, 35kAIC at 480VAC, and 18kAIC at 600VAC.
Does this breaker include ground fault protection?
No. The Micrologic 3.0A trip unit provides Long-Time and Instantaneous (LI) protection only. If ground fault protection is required, you will need a breaker with an LSIG trip unit, such as a Micrologic 6.0A.
Is the PGA36060U41A rated for 100% continuous operation?
No, this is a standard 80% rated circuit breaker. For a 100% rated version, the catalog number would include a C suffix before the trip unit designation, such as PGA36060CU41A.
