Product FAQs
6 answersWhat panelboards are compatible with the Siemens BQ1B01500S01?
This bolt-on circuit breaker is designed for installation in Siemens P1, P2, and P3 panelboards.
What does the 00S01 suffix indicate on the BQ1B01500S01 catalog number?
The 00S01 suffix means this breaker includes a factory-installed 120VAC shunt trip. This accessory allows the breaker to be opened remotely when a 120V control voltage is applied.
Can I use the BQ1B01500S01 to replace a standard BQ1B015 breaker?
You should only use this model if your control circuit requires a 120VAC shunt trip. If your application does not require remote tripping capabilities, the standard BQ1B015 is the correct replacement.
What wire gauges are supported by the terminals on this 15A breaker?
The load lugs accept 14 to 10 AWG copper wire, or 12 to 10 AWG aluminum wire.
How does the thermal-magnetic trip unit protect the circuit?
The thermal component provides long-time protection against sustained overloads, while the magnetic component provides instantaneous protection to quickly clear short circuits.
Does this breaker snap into place or bolt to the bus?
The BQ1B01500S01 is a bolt-on breaker. It must be mechanically fastened to the panelboard bus bars with screws, which is typical for commercial P-series panels.
