Product FAQs
6 answersCan the PJA36120U41A be installed in legacy Square D I-Line panelboards?
Yes. Schneider Electric has confirmed that PowerPacT P-frame breakers are backwards compatible with older I-Line panelboards and switchboards. Always verify that your specific enclosure has sufficient bus capacity and physical space for a 1200A device.
What does the U41A suffix indicate on the catalog number?
The U41A designation specifies that the breaker is equipped with a Micrologic 3.0A electronic trip unit. This unit provides adjustable long-time and instantaneous (LI) protection along with a built-in ammeter for current monitoring.
Is this circuit breaker rated for 100 percent continuous duty?
No, the PJA36120U41A is standard rated for 80 percent continuous loads. If your application requires a 100 percent continuous current rating, you would need a variant with a C suffix, such as the PJA36120CU41A.
How many conductors do the load side lugs accept?
The mechanical load lugs on this model are designed to accept up to four conductors per phase. Each terminal port accommodates aluminum or copper wire ranging from 3/0 AWG to 500 kcmil.
Does the line side connection require a separate mounting strap kit?
No. The I-Line design features plug-on jaws on the line side that connect directly to the panelboard bus stack. This design eliminates the need for separate mounting straps, brackets, or hardware kits.
What parameters can be field adjusted on the Micrologic 3.0A trip unit?
The electronic trip unit features rotary dials that allow you to precisely adjust the long-time and instantaneous pickup settings. This adjustability helps ensure proper system coordination with upstream and downstream overcurrent devices.
