Square D PowerPact BGA161251 1-Pole 125A B-Frame MCCB I-Line
125A Frame | 125A | 1P | 65kA@240V, 35kA@480V, 18kA@600Y/347V | Thermal-Magnetic (Fixed)
The BGA161251 PowerPact B-Frame MCCB from Square D by Schneider Electric offers single-pole 125-ampere rated thermal-magnetic circuit protection engineered for commercial, industrial, and institutional electrical distribution systems requiring reliable overcurrent protection and superior fault current interruption performance. Featuring I-Line Plug-On connections for I-Line plug-on installation, this circuit breaker uses a sealed thermal-magnetic trip element providing factory-calibrated overload and instantaneous short-circuit protection at 600Y/347V AC operating voltage. With interrupting capacity of 65kA@240V, 35kA@480V, 18kA@600Y/347V, it is suitable for main, feeder, and branch circuit applications across commercial and industrial electrical systems. The proven dual-break contact architecture delivers superior arc management and consistent protective performance across 15,000 rated mechanical operations without requiring maintenance or field recalibration of trip settings. The I-Line plug-on mounting system allows this breaker to be installed and removed from compatible I-Line distribution equipment without tools, dramatically reducing installation labor and enabling rapid replacement during maintenance activities. Line-side connections are made through the integrated I-Line bus interface. The B-Frame compact design optimizes panel space while maintaining full safety clearances. Conductor accommodation spans 14 AWG through 2/0 AWG in copper or aluminum. Fully certified to UL 489, CSA C22.2 No.5, IEC/EN 60947-2, and additional international certifications (NOM, CCC, CE, EAC), the BGA161251 is approved for branch, feeder, and main breaker service worldwide. The extensive PowerPact B-Frame accessory portfolio encompasses auxiliary switches, shunt trip coils, undervoltage releases, time delay modules, rotary handles, cable operators, padlock devices, and diverse termination options for tailored system configurations.
