The BQD type circuit breakers are 1-Inch pole configurations and are available in 1, 2, or 3 pole construction. Voltage ratings of 120, 240, 277, and 480/277V AC are available. The BQD breaker is intended for panel board mounting. Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any 3rd party sellers to do so.
