1200A Frame | 250A | 3P | 125kA@240V, 100kA@480V, 25kA@600V | Electronic (MicroLogic 5.0A)
The Square D PowerPact PLL34250U43A represents Schneider Electric's P-Frame MCCB platform, offering comprehensive circuit protection up to 1200A. This 3-pole device is rated at 250A with 480V AC voltage capability and an interrupting capacity of 125kA@240V, 100kA@480V, 25kA@600V (Current-Limiting (L) interrupting class). It features a MicroLogic 5.0A ammeter trip unit with LSIG protection plus integrated current measurement, rated at 80% continuous current per NEC Article 240.6. The PLL34250U43A is configured with AL1200CB Lug connections for reliable cable termination. 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 PLL34250U43A 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. Physical dimensions of 10.04" H x 9.00" W x 5.79" D with an approximate weight of ~18 lbs ensure compatibility with standard enclosures.
