Product FAQs
4 answersWhat is the difference between Siemens BQ and BQH circuit breakers?
The primary difference is the short circuit interrupting rating. Standard BQ breakers are rated for 10kAIC at 240VAC, while BQH breakers, such as the BQ3B050H, feature a higher interrupting capacity of 22kAIC at 240VAC.
What equipment is compatible with the BQ3B050H circuit breaker?
This bolt-on breaker is designed for installation in Siemens Modular Meter Centers and legacy ITE panelboards that accept BQ frame circuit breakers.
Is the Siemens BQ3B050H suitable for HVAC applications?
Yes, this breaker is HACR rated, which means it is approved for use with heating, air conditioning, and refrigeration equipment.
Can the BQ3B050H be used in reverse feed applications?
Yes, standard Siemens BQH breakers can be backfed or used in reverse feed applications, provided the breaker is not specifically marked with Line and Load designations on the terminals.
