Product FAQs
8 answersWhich panelboards are compatible with the BQ1B015 circuit breaker?
This bolt-on molded case circuit breaker is designed for use in Siemens P1, P2, and P3 commercial panelboards. It is not compatible with standard plug-on residential load centers.
Can I use this breaker to replace an older ITE or Gould model?
Yes. Siemens acquired the ITE and Gould circuit breaker lines, making the Siemens BQ1B015 a direct, UL-listed replacement for older ITE or Gould BQ breakers with the identical catalog number.
What is the difference between a Siemens QP and a BQ circuit breaker?
While both are standard 1-inch wide breakers manufactured by Siemens, Type QP breakers are plug-on units designed for residential load centers. Type BQ breakers, like the BQ1B015, are bolt-on units specifically required for commercial distribution panelboards.
Is the BQ1B015 approved for use with air conditioning equipment?
Yes, this 15-amp breaker is HACR rated. This means it has been tested and approved for the unique electrical demands of heating, air conditioning, and refrigeration applications.
Can this breaker be used to regularly switch lighting circuits?
Yes, the BQ1B015 carries an SWD (Switching Duty) rating, meaning it is UL approved for regularly switching 120-volt fluorescent lighting loads without degrading or damaging the breaker mechanisms.
Is this breaker rated for high-intensity discharge lighting?
Yes, in addition to being SWD rated, the BQ1B015 is HID rated, making it suitable for protecting circuits that supply high-intensity discharge lighting fixtures.
Does this breaker come with the necessary connection lugs?
Yes, factory-installed load side lugs are included with the breaker. They are designed to accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire.
How does the thermal-magnetic trip unit protect the circuit?
The LI (Long-Time, Instantaneous) trip function uses a bimetallic thermal element to protect against gradual current overloads and a magnetic element to trip instantly in the event of a severe short-circuit.
