Product FAQs
7 answersWhat specific trip unit is included with the JGL36250U44X?
This breaker is equipped with a Micrologic 6.2 A (Ammeter) electronic trip unit. It provides adjustable LSIG (Long-Time, Short-Time, Instantaneous, and Ground-Fault) protection and includes integrated current metering.
What parameters can be adjusted on the Micrologic 6.2 A trip unit?
The Micrologic 6.2 A trip unit allows you to adjust the Long-Time pickup and delay, Short-Time pickup and delay, Instantaneous pickup, and Ground-Fault pickup and delay. This provides precise selective coordination for complex electrical distribution systems.
Do I need an external neutral current transformer to use the ground fault function on a 4-wire system?
Yes. Because this is a 3-pole breaker, applying its LSIG ground fault protection in a 3-phase, 4-wire system requires a compatible external neutral current transformer, such as catalog number S430563, to monitor the neutral current.
Can I add field-installable accessories like shunt trips or auxiliary contacts to this breaker?
Yes, the PowerPacT J-Frame supports a variety of field-installable internal accessories, including shunt trips, undervoltage releases, and auxiliary switches. These install directly into the accessory compartments located behind the front cover of the breaker.
What do the letters G and L signify in the JGL36250U44X catalog number?
In the Square D PowerPacT nomenclature, the G indicates the interrupting rating tier, which is 35kA at 480VAC. The L designates the termination type, meaning the breaker is unit-mounted with mechanical lugs on both the line and load sides.
Are the factory-installed lugs on the JGL36250U44X removable?
Yes, the standard mechanical box lugs can be removed and replaced in the field. The breaker can also be adapted to accept compression lugs or power distribution connectors if required for your specific installation.
Is this breaker compatible with Square D I-Line panelboards?
No. The JGL36250U44X is a unit-mount breaker designed to be backpan mounted in enclosures, switchboards, or industrial control panels. It does not have the plug-on jaw connections required for I-Line distribution panels.
