Product FAQs
8 answersWhat panelboards are compatible with the JDA36250U31X circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line plug-on connection on the line side and mechanical lugs on the load side.
Can I install this PowerPacT J-Frame breaker in older I-Line panelboards?
Yes, Schneider Electric has confirmed that newer PowerPacT J-Frame breakers are backwards compatible with older I-Line panelboards and switchboard distribution sections, provided the voltage and interrupting ratings meet your system requirements.
How does the JDA36250U31X mount into an electrical panel?
It utilizes the I-Line plug-on mounting system. The breaker is pressed onto the panelboard bus bars and secured using a ratcheting mechanism with a retaining screw, allowing for fast installation without line-side cabling.
Does the JDA36250U31X come with lugs on both the line and load sides?
No. Because it is an I-Line breaker, it features a plug-on connection for the line side. Mechanical lugs are only provided on the load side, which accept 3/0 AWG to 350 kcmil aluminum or copper wire.
What type of trip unit is included with the JDA36250U31X?
It is equipped with a MicroLogic 3.2 electronic trip unit. This provides adjustable long-time and instantaneous (LI) protection, offering precise overcurrent and short-circuit response compared to standard thermal-magnetic units.
Is the JDA36250U31X rated for 100 percent continuous current?
No, this specific PowerPacT J-Frame breaker is standard-rated to carry 80 percent of its 250A continuous current rating.
How do I identify the cause of a trip on the JDA36250U31X?
The MicroLogic 3.2 electronic trip unit features LED indicators that display the trip status. This allows maintenance personnel to quickly identify whether the fault was caused by an overload or a short circuit.
What does the U31X suffix indicate in the JDA36250U31X catalog number?
The U31X suffix designates that the breaker is equipped with a MicroLogic 3.2 electronic trip unit, providing adjustable long-time and instantaneous (LI) protection functions.
