3. Key Features & Standards
- EMC & Motor Protection: Reduces PWM dv/dt, mitigates bearing currents, suppresses radio interference
- Cable Extension: Enables long motor cables (critical for remote motor installations)
- Compatibility: For SINAMICS S120/G130/G120, MICROMASTER 4 series (380–480 V, up to ~132 kW motor)
- Compliance: CE, cULus, RoHS, IEC 61800-3, EN 61000-6-2/-3
- Design: Blocksize format, optimized for cabinet integration with matching drive modules
4. Installation & Application Notes
-
- Mount vertically (top/bottom airflow) in a ventilated cabinet; avoid direct sunlight/heat sources
- Derate for high altitude (>1000 m), high ambient temp (>40 °C), or continuous overload
- Use shielded motor cable for EMC compliance; bond shield at both ends
- Match reactor current rating to drive output current (do not undersize)
- Technical data subject to change; always verify with latest Siemens documentation
