No. The BQ series uses a bolt-on mounting method, where the breaker is physically bolted to the bus bar, while QP series breakers use a plug-in clip connection. These two styles are not interchangeable — your panelboard must be specifically designed to accept bolt-on breakers. Check your panel's interior label or send us your panel model number and we'll confirm compatibility.
The BQ3B030 is rated for 240V and is a 3-pole breaker designed for use in single-phase (120/240V) panelboards — for example, protecting a large 240V load requiring a multi-wire branch circuit. It is not rated for 208Y/120V or 480V three-phase systems. If you have a three-phase application, contact our team and we can help identify the correct breaker.
