Product FAQs
8 answersWhich panelboards are compatible with the BJA160201 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes the I-Line plug-in mounting system for quick, direct connection to the panel bus assembly.
What does the final digit in the BJA160201 catalog number indicate?
The "1" at the end of the catalog number indicates that this 1-pole breaker is factory-configured for a Phase A connection on the I-Line bus. For Phase B or Phase C connections, you must use catalog numbers BJA160202 or BJA160203, respectively.
Can the BJA160201 replace older Square D 1-pole breakers?
Yes, the PowerPacT B-Frame series is the modern replacement for legacy Square D FA and FH series breakers. The BJA160201 can directly replace older 20A, 1-pole I-Line models such as the FA14020A or FH16020A.
How does the BJA160201 connect to the power source?
It features an I-Line plug-in connection on the line side that snaps directly onto the panelboard bus. The load side utilizes a standard mechanical lug for the outgoing wire connection.
What wire sizes are accepted by the load-side lug on the BJA160201?
The included mechanical lug accepts wire gauges from 14 AWG up to 2/0 AWG. It is rated for use with both aluminum and copper conductors.
Is the trip unit on the BJA160201 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time thermal overload protection and the instantaneous magnetic short-circuit protection are factory-set and cannot be adjusted in the field.
Is the BJA160201 rated for 100% continuous current?
No, this is a standard-rated breaker. Per the National Electrical Code (NEC), it should be applied continuously at no more than 80% of its 20A rating.
Is the BJA160201 suitable for HVAC applications?
Yes, this PowerPacT B-Frame breaker is HACR rated, meaning it is tested and approved for use with heating, air conditioning, and refrigeration equipment.
