Product FAQs
7 answersWhat type of panelboards accept the JDA262002 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line side connection that mounts directly to the I-Line bus assembly, while the load side uses standard mechanical lugs.
What does the D in the JDA262002 catalog number indicate?
The D designates the interrupting rating level for this PowerPacT J-Frame breaker. It provides a maximum interrupting capacity of 25 kA at 240VAC, 18 kA at 480VAC, and 14 kA at 600VAC.
Are the trip settings adjustable on the JDA262002?
Yes, this thermal magnetic breaker features an adjustable magnetic trip function. While the thermal overload protection is fixed at 200 amps, the instantaneous magnetic trip can be adjusted to coordinate with specific load requirements or motor inrush currents.
What replacement lug kit is compatible with the JDA262002?
The AL250JD aluminum mechanical lug kit is compatible with 200A and 250A PowerPacT J-Frame breakers. These lugs accept one 3/0 AWG to 350 kcmil copper or aluminum conductor per phase.
Can the JDA262002 be used in direct current applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 20 kA.
What is the difference between the JDA262002 and the JGA262002?
Both are 200A, 2-pole I-Line breakers in the PowerPacT J-Frame family. The difference is the interrupting rating. The JDA has a D-rated interrupting capacity (18 kA at 480VAC), while the JGA has a higher G-rated interrupting capacity (35 kA at 480VAC).
How can I test the mechanical operation of the JDA262002?
The breaker features a push-to-trip button on the front faceplate. Pressing this button manually trips the breaker, allowing you to verify that the internal mechanical linkage is operating correctly for routine safety maintenance.
