Product FAQs
7 answersWhat type of panelboards are compatible with the Square D SFA1032A?
The SFA1032A is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes an I-Line style plug-in connection that mounts directly to the busbar.
What frame size does the SFA1032A belong to?
The SFA1032A is part of the Square D F-frame family of molded case circuit breakers. It shares the same physical footprint as other 1-pole F-frame I-Line breakers.
Is the SFA1032A rated for international applications?
Yes, the SFA series is an international I-Line molded case circuit breaker that meets IEC specifications. This makes it suitable for global industrial applications while still utilizing the standard Square D I-Line plug-in mounting system.
What type of trip unit is installed in the SFA1032A?
This breaker features a fixed thermal magnetic trip unit. It provides both long time (thermal) overload protection and instantaneous (magnetic) short circuit protection. The trip settings are factory fixed and non-interchangeable.
How does the SFA1032A connect to the panelboard?
It features an I-Line style plug-in connection. The breaker jaws clamp directly onto the panelboard busbar, providing a secure electrical connection on the line side, while the load side uses standard mechanical lugs.
What wire sizes are accepted by the load lugs on the SFA1032A?
The mechanical lugs on this 32A breaker accept wire ranging from 14 AWG to 4 AWG. Ensure you torque the lugs to the manufacturer specifications printed on the breaker label.
How can I tell if the SFA1032A has tripped?
When the breaker trips due to an overload or short circuit, the operating handle will move to a central tripped position, halfway between ON and OFF. To reset the device, you must first push the handle completely to the OFF position before turning it back ON.
