Product FAQs
8 answersWhat enclosures or panels are compatible with the JGL36250SA?
This unit-mount breaker is designed for use in Square D J-Frame enclosures, switchboards, motor control centers, and industrial control panels. It is not compatible with I-Line panelboards.
Can I install the JGL36250SA in an I-Line panelboard?
No, the JGL36250SA is a unit-mount breaker with lugs on both the line and load sides. For I-Line panelboards, you need the plug-in equivalent, such as the JGA36250SA.
What does the SA suffix indicate on the JGL36250SA?
The SA suffix means this breaker includes a factory-installed 120VAC shunt trip (110-130 VAC control voltage), allowing the breaker to be tripped remotely.
Is the trip unit on the JGL36250SA adjustable?
Yes, it features a thermal-magnetic trip unit with fixed thermal protection (long-time) and an adjustable magnetic trip (instantaneous) to fine-tune short-circuit protection.
What size wire does the JGL36250SA accept?
The standard lugs accept one 3/0 AWG to 350 kcmil aluminum or copper wire per phase.
Can the JGL36250SA be reverse fed?
Yes, this PowerPacT J-Frame thermal-magnetic circuit breaker is suitable for reverse-fed applications.
