Product FAQs
7 answersWhich panelboards are compatible with the Siemens BQ3B060?
This 3-pole breaker is designed for bolt-on installation in compatible Siemens and legacy ITE panelboards, including the P1, P2, and P3 series panels that accept BQ frame circuit breakers.
What is the recommended terminal lug torque for the BQ3B060?
The load side terminal lugs on the BQ3B060 require a tightening torque of 50 to 70 in-lb for 6 AWG to 4 AWG wire. The panel mounting screws require a torque of 25 to 30 in-lb. Always verify exact specifications on the physical breaker label before installation.
Will the Siemens BQ3B060 replace an older ITE breaker with the same part number?
Yes, Siemens acquired ITE and continues to manufacture the BQ series. The Siemens BQ3B060 is a direct replacement for the legacy ITE BQ3B060 circuit breaker, providing the exact same form, fit, and function.
Is the BQ3B060 suitable for HVAC applications?
Yes, this circuit breaker is HACR rated. It is certified to safely handle the inrush currents and motor-driven loads associated with commercial heating, air conditioning, and refrigeration equipment.
Does the BQ3B060 come with lugs, or are they sold separately?
The breaker is supplied from the factory with standard load-side lugs installed. These lugs accommodate 8 to 4 AWG copper conductors or 8 to 2 AWG aluminum conductors.
Can the Siemens BQ3B060 be reverse fed?
Yes. Standard Siemens BQ series thermal-magnetic circuit breakers do not have strict line and load markings, which means they are suitable for reverse feed applications as long as the installation complies with local electrical codes.
Will this bolt-on breaker fit in a standard residential load center?
No. The BQ3B060 is a bolt-on molded case circuit breaker engineered for commercial and industrial panelboards. It is not compatible with standard load centers that require plug-on type breakers like the Siemens QP series.
