Product FAQs
5 answersWhat is the function of the switching neutral on the BG230?
The switching neutral design provides an additional pole that disconnects the neutral conductor when the breaker trips or is manually opened. The neutral pole does not connect to the energized bus. This feature is required in applications where all conductors must be completely disconnected from the power source.
What is the direct replacement for the BG230 circuit breaker?
Siemens has officially replaced the BG230 with the newer BG2B030 catalog number. Both models share the same physical dimensions, bolt-on mounting, and switching neutral functionality.
How many panel spaces does the BG230 require for installation?
This breaker requires two standard panel spaces. One space connects to the energized bus bar, while the second space accommodates the switching neutral pole.
Is the BG230 suitable for HVAC equipment protection?
Yes, this circuit breaker is HACR rated, meaning it is tested and approved for safely protecting heating, air conditioning, and refrigeration circuits.
Which Siemens panelboards are compatible with this breaker?
The BG230 is designed for use in Siemens panelboards that accept bolt-on B-frame circuit breakers. Ensure your specific panel interior supports switching neutral configurations before installation.
