Product FAQs
7 answersCan I install the BJA260701 in a standard QO or Homeline load center?
No. This is an I-Line molded case circuit breaker designed specifically for Square D I-Line panelboards and switchboards. It features a plug-on line connection that is incompatible with standard residential load centers.
How does the BJA260701 mount into the panel?
It utilizes the Square D I-Line mounting system. The line side features plug-on jaws that engage directly with the panelboard bus stack, while the load side uses standard mechanical lugs for wire termination.
What type of wire can be used with the load side lugs?
The factory-installed load lugs accept 14 AWG through 2/0 AWG aluminum or copper conductors. Ensure proper torque specifications are followed during installation as outlined by Schneider Electric.
Can this breaker be used in DC applications?
Yes, the BJA260701 is rated for use in DC circuits up to 250VDC, where it provides a 50kA interrupting rating. Verify your specific DC system requirements before installation.
Are the trip settings adjustable on this breaker?
No. This PowerPacT B-frame breaker features a thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip functions. It does not offer adjustable dials.
What do the letters in the BJA260701 catalog number mean?
In the Square D PowerPacT nomenclature, "B" indicates the B-frame size, "J" denotes the interrupting rating (65kA at 480VAC), and "A" specifies the I-Line mounting style. The remaining digits indicate it is a 2-pole, 600V-rated, 70-amp breaker.
Can the BJA260701 be reverse fed?
Yes. This PowerPacT B-frame breaker features a thermal-magnetic trip unit and is suitable for reverse-fed applications.
