Product FAQs
8 answersWhat does the "SA" suffix indicate on the JDL36175SA catalog number?
The "SA" suffix denotes that this breaker includes a factory-installed 110-130VAC shunt trip. This allows the breaker to be tripped remotely via a control signal for safety interlocking or automated shutdown sequences.
How does the unit-mount design of the JDL36175SA differ from I-Line breakers?
As a unit-mount breaker, the JDL36175SA bolts directly to a backpan or mounting plate using a feed-thru connection. It does not have the plug-on jaw connectors required for Square D I-Line distribution panelboards.
What type of trip unit is equipped on the JDL36175SA?
It utilizes a thermal-magnetic trip unit with LI (Long-Time, Instantaneous) functions. The thermal element for overload protection is fixed, while the magnetic instantaneous trip threshold can be adjusted by the user to coordinate with downstream loads.
Are the standard lugs on the JDL36175SA rated for aluminum wire?
Yes, the factory-installed lugs are dual-rated for both aluminum (Al) and copper (Cu) conductors, accepting wire sizes from 4 AWG to 4/0 AWG.
Can the JDL36175SA be applied in DC circuits?
Yes, this breaker is rated for 250VDC systems, providing a 20kAIC interrupting rating for direct current applications, in addition to its standard AC ratings.
What equipment is the JDL36175SA designed to be installed in?
This PowerPacT J-Frame breaker is suitable for use in Square D industrial enclosures, switchboards, motor control centers, and custom-built control panels.
Does the JDL36175SA provide ground fault equipment protection?
No, this model provides standard thermal-magnetic overcurrent and short-circuit protection. It does not feature integrated ground fault protection or earth leakage detection.
Can the JDL36175SA be reverse-fed in a panel?
Yes, standard thermal-magnetic PowerPacT J-Frame breakers like the JDL36175SA are suitable for reverse-fed applications, allowing line power to be supplied to either the top or bottom terminals.
