The ComPacT NPLLE44100U73RE1 from Schneider Electric represents the NS630b-NS1600 series, offering versatile IEC-rated circuit protection. This 4-pole device is rated at 1000A with 690V AC (IEC) voltage capability and an interrupting capacity of Icu 150kA@380/415V (IEC), 150kA@240V (Current-Limiting (L) interrupting class). It features a MicroLogic 5.0H harmonic trip unit with LSIG protection, harmonic analysis, and Modbus communication, rated at 80% continuous current per NEC Article 240.6. The NPLLE44100U73RE1 is configured with Standard IEC Lug connections for reliable cable termination. This breaker is fully compliant with IEC 60947-2 international standards, ensuring compliance across North American and international installations. Engineers and contractors rely on the NPLLE44100U73RE1 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 (Per IEC standards) 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 327mm H x 210mm W x 147mm D with an approximate weight of ~14 kg ensure compatibility with standard enclosures.
