If you're unsure whether this breaker fits your specific panelboard or switchboard, send us your panel model number and we'll confirm compatibility.
The BGA34025 uses Square D's I-Line plug-in mounting, which means it is designed for Square D I-Line panelboards and switchboards used in commercial and industrial applications. It is not compatible with residential loadcentres such as QO or Homeline panels. Send us your panel model number and we'll confirm the fit.
The BGA-frame I-Line series has been superseded by newer Square D MCCB lines in many applications, and certain configurations can be difficult to source through standard distribution channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers — contact us for current availability on the BGA34025.
The BGA34025 is rated and listed for 480Y/277 V at 35 kA. While a higher-voltage rated breaker can generally be applied at lower voltages, the interrupting rating and any UL listing must be verified for your specific system voltage and fault current. We recommend consulting your engineer of record and confirming the application with us before proceeding.
