Product FAQs
5 answersWhich load centers accept the SDT230 circuit breaker?
This breaker is engineered specifically for legacy Square D Trilliant load centers. It features a unique plug-on mounting design that only fits Trilliant bus bars.
Are Square D QO or Homeline breakers interchangeable with the SDT series?
No. QO and Homeline breakers feature completely different physical dimensions and bus connections. They cannot be installed in Trilliant load centers, which strictly require SDT frame breakers.
Are tandem or space-saver breakers available for Trilliant load centers?
No. Square D never manufactured tandem or twin breakers for the Trilliant product line. Each circuit requires a full-size SDT breaker space.
Is the Square D Trilliant product line still in production?
The Trilliant line of load centers has been discontinued and is considered obsolete. Replacement breakers like the SDT230 remain available specifically to service existing Trilliant installations without requiring a full panel replacement.
What applications typically require a 30A 2-pole breaker?
A 30A, 240VAC double-pole breaker is commonly installed for dedicated residential loads such as electric water heaters, small air conditioning condensers, or electric clothes dryers. Always verify the nameplate rating of the connected equipment to ensure proper sizing.
