Product FAQs
5 answersWhat is the difference between the Siemens BQ1B030 and the BQ1B030H?
The H designation indicates a higher interrupting rating. While the standard BQ1B030 is rated for 10kAIC at 120V, the BQ1B030H is rated for 22kAIC at 120V, making it suitable for commercial systems with higher available fault currents.
Can the BQ1B030H be used to replace older ITE or Gould circuit breakers?
Yes, Siemens acquired ITE and Gould, and the current Siemens BQ frame breakers are direct, exact-fit replacements for legacy ITE and Gould BQ bolt-on circuit breakers.
Is the Siemens BQ1B030H suitable for reverse feed applications?
Yes, standard Siemens BQ thermal magnetic circuit breakers are not marked with Line and Load designations, meaning they are UL listed for reverse feed or backfeed applications.
Which panelboards are compatible with the BQ1B030H circuit breaker?
This bolt-on breaker is designed specifically for installation in Siemens P1, P2, and P3 series panelboards. It is not compatible with standard plug-on residential load centers.
Is this circuit breaker HACR rated for HVAC equipment?
Yes, Siemens BQ frame molded case circuit breakers are HACR rated, making them suitable for use with heating, air conditioning, and refrigeration equipment that requires this specific protection profile.
