Product FAQs
4 answersWhat panelboards are compatible with the Square D 992330?
This breaker is designed exclusively for legacy Square D Type ML panelboards. It provides an exact fit for facilities replacing discontinued ML Series components, allowing you to maintain existing infrastructure without a complete panel upgrade.
Can I install the 992330 in a Square D I-Line panelboard?
No. The 992330 utilizes a specific bolt-on mounting configuration for older Type ML panelboards. It is not compatible with I-Line plug-on systems, which largely replaced the ML series in industrial applications.
Is the Square D 992330 a current production model?
No, the 992330 is part of the obsolete 99 Series. It is typically sourced as a replacement part to service existing Type ML electrical panels that have been out of production for several decades.
What frame designation applies to the 992330 breaker?
The 992330 is built on the Square D Type 992 frame. This specific frame size and bolt-on configuration is required to properly align with the busbars in legacy Type ML panelboards.
