Product FAQs
6 answersWhat load centers are compatible with the Square D SDT235?
The SDT235 is designed exclusively for use in legacy Square D Trilliant load centers. It will not fit in standard Square D QO or Homeline panels.
Can I use a Square D QO or Homeline breaker to replace the SDT235?
No. Square D Trilliant load centers require SDT frame breakers. Modern QO and Homeline breakers have different mounting mechanisms and are not interchangeable with the SDT235.
What wire gauge is accepted by the box lugs on the SDT235?
The box lug terminals on this 35A breaker accept wire ranging from 8 AWG to 2 AWG. Ensure your conductors are sized appropriately for a 35A circuit per the NEC.
How does the thermal-magnetic trip mechanism operate in the SDT235?
The breaker uses a fixed thermal element to provide long-time protection against sustained overloads, combined with a magnetic element for instantaneous tripping during short circuits.
How is the SDT235 installed into a Trilliant panel?
This breaker features a plug-on design that snaps directly into the busbar of a compatible Square D Trilliant load center, requiring no bolt-on hardware.
Are Square D Trilliant load centers still manufactured?
No, the Trilliant panel system is obsolete. However, SDT frame breakers like the SDT235 are still used to maintain and service these existing legacy installations safely without requiring a full panel swap.
