Product FAQs
6 answersWhat panelboards accept the FH16030C circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes a plug-in mounting style that connects directly to the I-Line bus assembly.
What does the C suffix in the FH16030C catalog number mean?

What is the modern replacement for the legacy FH16030C?
