Square D PowerPact BKA160251 1-Pole 25A B-Frame MCCB I-Line
125A Frame | 25A | 1P | 100kA@240V, 65kA@480V, 65kA@600Y/347V | Thermal-Magnetic (Fixed)
Schneider Electric's Square D PowerPact BKA160251 delivers single-pole 25-ampere circuit protection in the compact and versatile B-Frame molded case platform, providing dependable thermal-magnetic overcurrent and short-circuit protection for demanding commercial and industrial power distribution applications. Configured for I-Line plug-on installation with I-Line Plug-On terminations, this circuit breaker employs a factory-calibrated thermal-magnetic trip unit delivering tamper-resistant overcurrent protection. The sealed trip element provides both long-time overload and instantaneous short-circuit trip functions without requiring field adjustment. Rated at 600Y/347V AC with interrupting capacity of 100kA@240V, 65kA@480V, 65kA@600Y/347V, it addresses demanding fault current conditions. Schneider Electric's proprietary dual-break contact system ensures rapid arc extinction and reliable current interruption throughout the rated mechanical life of 15,000 operations, maintaining consistent protective performance. Designed for I-Line plug-on mounting, this breaker slides directly onto I-Line bus bars in compatible panelboards and switchboards, enabling rapid installation, removal, and replacement without disconnecting individual conductors. This significantly reduces installation time and simplifies maintenance operations. The compact B-Frame housing optimizes equipment space utilization while maintaining required electrical clearances and creepage distances. Wire accommodation ranges from 14 AWG to 2/0 AWG for copper and aluminum conductors. Meeting UL 489, CSA C22.2 No.5, IEC/EN 60947-2, and international NOM, CCC, CE, EAC certifications, the BKA160251 supports diverse installation requirements globally. The PowerPact B-Frame accessory ecosystem includes auxiliary contacts for remote monitoring, shunt trips for emergency disconnect, undervoltage releases for power quality protection, various handle and locking options, and multiple termination accessories for flexible wire management and system design configurations.
