Siemens 6SE6420-2AC25-5CA1 Micromaster 420 Frequency Converter

Description

The 6SE6420-2AC25-5CA1 is a Micromaster 420 series frequency converter engineered for versatile motor control in industrial applications. This drive accepts a 3-phase supply voltage of 200–240 V AC (±10%) at 47–63 Hz and delivers a nominal power output of 5.5 kW. It features an integrated Class A filter for EMC compliance and supports both constant torque and square-law torque applications, with an overload capacity of 150% for 60 seconds. Housed in an IP20-rated enclosure, the drive is designed for robust operation in ambient temperatures ranging from -10 degC to +50 degC. Note: This unit is supplied without an AOP (Advanced Operator Panel) or BOP (Basic Operator Panel).

Installation Guidelines

• Mounting: Install the frequency converter vertically within a control cabinet to ensure adequate airflow through the internal heatsinks.
• Clearance: Maintain the manufacturer-specified ventilation clearances to prevent thermal accumulation.
• Wiring: Connect 3-phase power input and motor cables securely; ensure proper shielding is utilized to maintain EMC Class A compliance.
• Grounding: Establish a low-impedance ground connection to the chassis to ensure safe and stable operational conditions.
• Environment: Protect the unit from excessive moisture, oil mist, and corrosive particulates to maintain the integrity of the IP20 electronics.
