Product FAQs
9 answersWhat panelboards are compatible with the JDA36175SA?
This I-Line molded case circuit breaker is designed exclusively for Square D I-Line panelboards and switchboards. It will not fit in standard NQ, NF, or QO series load centers.
What does the "SA" suffix indicate on this circuit breaker?
The "SA" suffix designates that the breaker includes a factory-installed 120VAC shunt trip accessory. This allows the breaker to be opened remotely via a control signal.
Can the JDA36175SA be used to replace a legacy KA36175 breaker?
Yes, the PowerPacT J-Frame series is the direct replacement for the discontinued Square D KA-Frame breakers. Note that this specific model includes a 120VAC shunt trip, so ensure your application requires remote tripping capabilities before substituting.
How does the I-Line mounting system connect to the panelboard?
The I-Line plug-on design allows the line side of the breaker to snap directly onto the panelboard bus assembly. This eliminates the need for line-side wire terminations and significantly reduces installation time. The load side utilizes standard mechanical lugs.
Are the trip settings adjustable on the JDA36175SA?
This thermal-magnetic breaker features a fixed thermal element for long-time overload protection and an adjustable magnetic dial. The adjustable magnetic trip allows electricians to fine-tune the instantaneous short-circuit response to coordinate with other devices in the system.
Does this breaker provide ground fault protection?
No, the JDA36175SA is equipped with a standard LI (Long-Time and Instantaneous) trip unit. It does not provide equipment ground fault (LSIG) or personnel ground fault (GFCI) protection.
Is this breaker suitable for DC control circuits?
Yes, the thermal-magnetic trip unit allows this breaker to be used in DC applications up to 250VDC, making it suitable for industrial DC control panels or battery systems.
How can I manually test the tripping mechanism on the JDA36175SA?
This PowerPacT J-Frame breaker includes an integral push-to-trip button on the front cover. Pressing this button manually exercises the tripping mechanism, moving the handle to the center tripped position to verify mechanical operation.
What is the difference between the JDA36175 and the JDA36175SA?
Both are 175A, 3-pole PowerPacT J-Frame breakers. The JDA36175 is the standard model, while the JDA36175SA includes a factory-installed 120VAC shunt trip for remote operation.
