Product FAQs
6 answersWhich panelboards are compatible with the Siemens BQD6220 circuit breaker?
The BQD6220 is designed for use in Siemens P1, P2, and P3 panelboards. Because it is a bolt-on breaker, your panel must be configured with the appropriate bolt-on bus hardware to accept it.
What wire sizes and materials are supported by the lugs on the BQD6220?
The factory-installed lugs accept 14 to 6 AWG copper (Cu) conductors or 12 to 6 AWG aluminum (Al) conductors. Always verify the required torque specifications printed directly on the breaker label before terminating your wires.
Can the BQD6220 be used in DC power applications?
Yes, this breaker is rated for use in DC systems up to 125/250VDC, where it provides an interrupting capacity of 14kAIC. This makes it suitable for specific control circuits and DC distribution panels.
What does the 600/347VAC voltage rating indicate for this breaker?
This is a slash rating, meaning the breaker is intended for use on solidly grounded wye electrical systems where the line-to-neutral voltage does not exceed 347V and the line-to-line voltage does not exceed 600V.
What type of trip mechanism does the BQD6220 utilize?
It features a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against overloads, while the magnetic component provides instantaneous protection against short circuits.
Can the BQD6220 be mounted on a DIN rail?
The BQD6220 is designed specifically as a bolt-on breaker for panelboards. For DIN rail applications, Siemens manufactures the CQD frame series, which serves as the cable-in, cable-out equivalent to the BQD.
