Product FAQs
7 answersWhat panelboards are compatible with the Square D SFA1100A circuit breaker?
The SFA1100A is designed exclusively for use in Square D I-Line power distribution panelboards and switchboards that accept I-Line style plug-in breakers. Always verify your specific panel labeling to ensure SFA frame breakers are permitted.
How does the SFA1100A connect to the panelboard bus?
This breaker features an I-Line style plug-in connection. It engages directly onto the panelboard bus system, allowing for efficient installation and replacement without the need for bolted bus connections.
What type of trip unit is equipped on the SFA1100A?
It features a fixed thermal magnetic trip unit providing long-time and instantaneous (LI) overcurrent protection. The thermal and magnetic trip settings are factory fixed and cannot be adjusted in the field.
What wire sizes are accepted by the standard lugs on the SFA1100A?
The standard lugs on this 100A breaker accept wire gauges ranging from 14 AWG to 1/0 AWG. Ensure you use properly sized conductors as specified by the National Electrical Code for your specific application.
Can the SFA1100A be installed in a 480V or 600V electrical system?
No. The SFA1100A is strictly rated for a maximum of 240V AC. Installing it in systems with higher voltages violates its safety listing and creates a severe electrical hazard.
Is the SFA1100A interchangeable with Square D QO or Homeline breakers?
No. The SFA1100A is an I-Line molded case circuit breaker designed for commercial and industrial power distribution panels. It will not fit in residential QO or Homeline load centers.
What does the 25kAIC rating on the SFA1100A signify?
The 25kAIC rating indicates that the breaker can safely interrupt up to 25,000 amps of short-circuit fault current at 240V AC without sustaining internal damage or causing an external hazard.
