Square D PowerPact BJA260701 2-Pole 70A B-Frame MCCB I-Line
125A Frame | 70A | 2P | 100kA@240V, 65kA@480V, 25kA@600Y/347V | Thermal-Magnetic (Fixed)
The Square D PowerPact BJA260701 is a Two-Pole 70A B-Frame molded case circuit breaker from Schneider Electric, engineered for reliable thermal-magnetic overcurrent protection in commercial and industrial electrical distribution systems requiring high-performance fault interruption capability. This I-Line plug-on circuit breaker features I-Line Plug-On connections and incorporates a fixed, factory-sealed thermal-magnetic trip unit that provides coordinated long-time overload protection and instantaneous short-circuit interruption without requiring field adjustment or calibration. Rated for 600Y/347V AC applications with an interrupting capacity of 100kA@240V, 65kA@480V, 25kA@600Y/347V, it safely handles high-magnitude fault currents in diverse electrical system configurations. The B-Frame design incorporates Schneider Electric's dual-break contact technology for enhanced arc interruption, consistent current clearing performance, and extended contact service life rated to 15,000 mechanical operations. The compact B-Frame enclosure design minimizes panelboard space requirements while maintaining full electrical performance ratings, safety clearances, and creepage distances mandated by applicable safety standards. This I-Line plug-on configuration enables quick installation and removal from compatible I-Line panelboards and switchboards without tools, significantly reducing installation labor and system maintenance downtime. The breaker accommodates wire sizes from 14 AWG through 2/0 AWG in copper or aluminum conductors. Certified to UL 489, CSA C22.2 No.5, IEC/EN 60947-2, NOM, CCC, CE, and EAC standards, this MCCB is approved for installation worldwide. Compatible with the complete PowerPact B-Frame accessory portfolio including auxiliary contacts (OF/SD), shunt trip coils (MX), undervoltage releases (MN), rotary operating handles, padlock devices, and cable operating mechanisms for comprehensive power distribution system integration and enhanced operational flexibility.
