Product FAQs
8 answersWhat panelboards accept the BJA160153 circuit breaker?
This breaker is designed exclusively for Square D I-Line distribution panelboards and switchboards. It features a plug-on stab connection that mounts directly to the I-Line bus assembly.
Can the PowerPacT B-frame BJA160153 replace older Square D breakers?
Yes, the PowerPacT B-frame series is the direct replacement for legacy F-frame (FA and FH) molded case circuit breakers used in I-Line panelboards. It fits the same mounting space dimensions to simplify retrofits.
What wire sizes are compatible with the lugs on this breaker?
The factory-installed mechanical lugs accept 14 AWG to 2/0 AWG aluminum or copper conductors. Always torque the terminals to the specifications printed on the breaker faceplate.
What does the J in the BJA160153 catalog number indicate?
The J designates the interrupting rating tier within the PowerPacT B-frame family. It provides a high interrupting capacity of 100kA at 240VAC, 65kA at 480Y/277VAC, and 25kA at 600Y/347VAC.
Is this 1-pole breaker suitable for DC applications?
Yes, the BJA160153 is rated for use in DC circuits up to 125VDC, with a DC interrupting rating of 50kA.
What type of trip mechanism does the BJA160153 use?
It utilizes a thermal-magnetic trip unit with fixed long-time and instantaneous protection. The thermal element protects against sustained overloads, while the magnetic element trips immediately during short circuits.
Does this breaker require a separate mounting bracket for installation?
No, the I-Line mounting design integrates the mounting bracket and plug-on jaw directly into the breaker. It snaps onto the panelboard bus, eliminating the need for separate mounting hardware.
Can I install the BJA160153 in a standard QO or Homeline residential load center?
No, this is an I-Line molded case circuit breaker intended for commercial and industrial distribution panels. It will not fit in residential plug-on load centers like QO or Homeline.
