Product Description

Description

The 6SE6440-2UE21-5CA1 is a MICROMASTER 440 frequency converter engineered for demanding industrial motor control applications. This high-performance inverter is designed for 3-phase supply voltages ranging from 500 V to 600 V AC (±10%) at 47-63 Hz. It provides a constant torque power rating of 1.5 kW with significant overload capabilities—150% for 60 seconds and 200% for 3 seconds—making it suitable for complex dynamic loads. For square-law torque applications (such as centrifugal pumps or fans), the drive supports up to 2.2 kW. The unit features an IP20-rated enclosure for protected cabinet mounting and is optimized for operation in ambient temperatures between -10 degC and +50 degC. This configuration is supplied without a Basic Operator Panel (BOP) or Advanced Operator Panel (AOP).

Installation Guidelines

  • Mounting: The unit must be mounted vertically in a control cabinet. Ensure sufficient ventilation space is provided above and below the device to facilitate airflow.
  • Ambient Conditions: Ensure the cabinet installation protects the unit from moisture, conductive dust, and corrosive vapors. Maintain internal cabinet temperature within the specified -10 degC to +50 degC range.
  • Wiring: Connect the 3-phase supply to the input terminals and motor leads to the output terminals. Always ensure that the power supply is isolated before wiring.
  • Grounding: Establish a robust connection to the system ground bus to ensure compliance with EMC requirements and operator safety.
  • Commissioning: As this unit is provided without an operator panel, configuration will require an external BOP/AOP or PC-based software tools for parameter setup.
