Product FAQs
12 answersWhat legacy circuit breakers does the PowerPacT BJA160251 replace?
The PowerPacT B-frame series is designed to replace legacy Square D FA and FH series molded case circuit breakers in I-Line panelboards and switchboards.
Is the BJA160251 compatible with older Square D I-Line panelboards?
Yes, Schneider Electric has confirmed that PowerPacT B-frame breakers will fit the basic construction of previously installed I-Line panelboards without requiring a panel upgrade.
Which phase connection does the BJA160251 use in an I-Line panelboard?
The BJA160251 is a 1-pole breaker specifically configured for an A-phase connection on the I-Line bus, as indicated by the "1" suffix in the catalog number.
What is the difference between the BJA160251 and the BJA160253?
Both are 1-pole, 25-amp PowerPacT B-frame I-Line breakers, but the last digit indicates the phase connection. The BJA160251 connects to the A-phase, while the BJA160253 connects to the B-phase on the panelboard bus.
What are the short-circuit interrupting ratings for the BJA160251 at higher voltages?
In addition to its 100kAIC rating at 240VAC, this J-interrupting tier breaker is rated for 65kAIC at 480Y/277VAC and 25kAIC at 600Y/347VAC.
Is the BJA160251 rated for 100 percent continuous loading?
No, this breaker is standard-rated. Per the National Electrical Code (NEC), standard circuit breakers may only be applied continuously at up to 80 percent of their maximum current rating.
What type of wire lugs are included with the BJA160251?
This breaker features EverLink wiring lugs on the load side, which are designed to maintain constant contact pressure on fine stranded conductors and accommodate 14 AWG to 2/0 AWG aluminum or copper wire.
What is the recommended wire stripping length for the EverLink lugs on this breaker?
The EverLink lugs on the PowerPacT B-frame breakers require a wire stripping length of 0.79 inches (20 mm) for proper installation.
Can I convert this I-Line plug-on breaker to a unit-mount or lug-in and lug-out configuration?
No, the I-Line shroud and plug-on connectors cannot be removed or retrofitted in the field. If you need a unit-mount breaker with lug-in and lug-out terminations, you must order a different PowerPacT B-frame catalog number.
Can I field-install accessories like auxiliary switches on the BJA160251?
Yes, PowerPacT B-frame circuit breakers support field-installable electrical accessories, including auxiliary switches and alarm contacts, which can be added to accommodate last-minute design changes.
Does the BJA160251 include dual-break rotating contacts?
Yes, all PowerPacT B-frame circuit breakers feature dual-break rotating contacts that reduce peak current and let-through energy during a short-circuit fault, enhancing overall equipment protection.
At what ambient temperature is the thermal trip unit of the BJA160251 calibrated?
The thermal-magnetic trip units in PowerPacT B-frame circuit breakers are calibrated for operation in a 104 degree Fahrenheit (40 degree Celsius) free-air ambient temperature.
