Product FAQs
9 answersWhich panelboards are compatible with the JDA36225 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. The plug-in jaw mechanism mounts directly onto the I-Line bus.
How much mounting space does this 3-pole breaker require in an I-Line panel?
It requires 4.5 inches of I-Line bus mounting space. Each phase occupies 1.5 inches.
What are the magnetic hold and trip threshold values for this 225A breaker?
The JDA36225 features a magnetic hold current of 1125A and a magnetic trip current of 2250A.
What is the standard replacement lug kit for this breaker?
The factory replacement lug kit is catalog number AL250JD, which accepts one 3/0 AWG to 350 kcmil aluminum or copper wire per phase.
What is the recommended tightening torque for the AL250JD load side lugs?
The load side wire lugs should be torqued to 221 lb-in (25 N.m) when securing properly sized aluminum or copper conductors.
Does this breaker include both line and load side wire lugs?
No, it is equipped with mechanical lugs on the load side only. The line side utilizes the integrated I-Line plug-in jaw connection to attach directly to the panelboard bus.
Does this breaker feature a push-to-trip button?
Yes, it includes a push-to-trip mechanism on the front cover. This allows you to mechanically test the tripping function and verify the breaker mechanism is operating correctly before performing maintenance.
Is this circuit breaker HACR rated?
