3200A Frame | 3200A | 4P | Icu 85kA@380/415V, 125kA@240V (IEC) | Electronic (MicroLogic 5.0A)
The ComPacT NRHFE46320U43R from Schneider Electric is part of the NS1600b-NS3200 series, engineered for demanding global power distribution. This 4-pole device is rated at 3200A with 440V AC (IEC) voltage capability and an interrupting capacity of Icu 85kA@380/415V, 125kA@240V (IEC) (High (H) 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 NRHFE46320U43R is equipped with busbar connection for direct mounting in power distribution switchgear. 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 NRHFE46320U43R 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 Bus connection 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 381mm H x 381mm W x 178mm D with an approximate weight of ~55 kg ensure compatibility with standard enclosures.
