Overview
The Phoenix Contact 2948270 is a motor attenuation module designed for star-connected three-phase motors. It operates with a rated voltage of 500 V AC between phases and supports motor ratings up to 4 kW. The device functions as an RC combination resistor, providing electromagnetic interference suppression for motor windings. This component facilitates the protection of motor circuits by attenuating high-frequency noise generated during operation.
Feature Summary
- Provides electromagnetic interference suppression for motor windings
- Designed specifically for star-connected three-phase motor configurations
- Integrates RC combination resistance for circuit protection
Applications
- Star-connected three-phase motor protection
- Electromagnetic interference suppression in industrial motor drives
- Motor winding noise attenuation
Procurement Notes
Verify the specific application requirements against the 500 V AC rated voltage and 4 kW power limit before procurement. Confirm that the motor connection type matches the star configuration required by this module. Ensure compatibility with the control system's electromagnetic compatibility standards. Check for any obsolete status or availability constraints through official Phoenix Contact channels prior to ordering.
Selection Notes
Select this module when star-connected three-phase motors require dedicated attenuation for electromagnetic compatibility. It is suitable for applications involving motors up to 4 kW operating at 500 V AC. Consider this component if standard filtering is insufficient for winding noise reduction. Ensure the installation environment supports the thermal and electrical specifications of the RC combination module.
Part Context
This part belongs to the EMG series of relay and interface modules from Phoenix Contact. It serves as a specialized accessory for motor control systems, focusing on signal integrity and noise reduction rather than primary switching functions. The module complements other automation components by addressing specific electromagnetic compatibility challenges in industrial motor applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing motor controllers before attempting substitution. Consult Phoenix Contact technical support for equivalent solutions if this specific model is unavailable.
