Product FAQs
7 answersWhat type of panelboard accepts the Square D SFA1016A circuit breaker?
This breaker is specifically designed for commercial and industrial Square D I-Line panelboards. It utilizes an I-Line style plug-in connection, which allows it to snap directly onto the panelboard bus assembly.
Which phase position does the SFA1016A connect to in an I-Line panelboard?
The A at the end of the SFA1016A catalog number indicates that this single-pole breaker is factory-configured to connect exclusively to the A-phase (L1) busbar in an I-Line panelboard. It cannot be installed on the B or C phases.
What wire sizes are supported by the SFA1016A terminal lugs?
The lugs on this breaker accommodate wire gauges from 14 AWG up to 4 AWG. Ensure you torque the connections to the manufacturer specifications printed on the breaker label during installation.
Are the thermal and magnetic trip functions on the SFA1016A adjustable?
No, the SFA1016A features fixed thermal and fixed magnetic trip settings. It provides standard long-time and instantaneous (LI) protection without the ability to dial in custom trip curves.
Can the SFA1016A be installed in residential QO or Homeline load centers?
No. The SFA1016A is an F-frame molded case circuit breaker with an I-Line plug-in mounting style. It will not fit in standard residential QO or Homeline load centers, which require completely different breaker form factors.
What type of protection does the SFA1016A provide?
This thermal-magnetic breaker provides both long-time (L) protection against sustained overloads and instantaneous (I) protection against short circuits.
Is the SFA1016A part of the standard FA frame family?
Yes, the SFA series belongs to the broader F-frame family of Square D molded case circuit breakers, but it is specifically built with an I-Line plug-in connection for I-Line panelboards.
