The Square D PowerPact MGA266002 is an 800A-frame molded case circuit breaker combining robust construction with sophisticated electronic trip capability. This 2-pole device is rated at 600A with 600V AC voltage capability and an interrupting capacity of 65kA@240V, 35kA@480V, 18kA@600V (Standard (G) interrupting class). It features a ET1.0 electronic trip unit providing basic overcurrent protection with adjustable settings, rated at 80% continuous current per NEC Article 240.6. The MGA266002 is featuring I-Line plug-in mounting for rapid installation and maintenance in Square D I-Line panelboards and switchboards. This breaker is UL 489 listed and CSA certified with dual UL/IEC ratings, ensuring compliance across North American and international installations. Engineers and contractors rely on the MGA266002 for its proven track record of reliability, ease of installation, and comprehensive protection capabilities. Field-installable accessories include shunt trip coils, undervoltage releases, auxiliary switches, alarm contacts, and motor operators for remote operation. This configuration is suitable for both new installations and retrofit applications in existing switchgear and panelboard assemblies. Maintenance intervals are minimized through the use of high-quality internal components and arc-quenching chamber technology. The wire range accommodates 1/0-500 kcmil Al/Cu conductors for flexible installation options. Quick-make quick-break contact mechanisms ensure reliable interruption regardless of handle operating speed or force applied.
