Overview
The FN3040-20-61-C21-R65 is a three-phase EMC/EMI line filter manufactured by Schaffner EMC Inc. It features a MnZn core and supports a current rating of 20 A with a voltage rating of 530 VAC (Delta) or 305 VAC. The unit utilizes M4 screw terminals for connection and is designed for chassis mounting. Key electrical specifications include a capacitance value of 220 nF and operation within a frequency range from DC to 60 Hz.
Feature Summary
- Designed for low leakage current applications in three-phase systems
- Utilizes MnZn core technology for effective EMI/EMI filtering
- Supports Delta configuration with ring terminal input and output options
Applications
- Industrial power distribution systems requiring low leakage
- Three-phase equipment connected to Delta networks
- Chassis-mounted EMC compliance solutions for heavy machinery
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct terminal type and mounting configuration. Confirm that the 20 A current rating and 530 VAC voltage specification align with your system requirements. Check for RoHS compliance status if required by your procurement standards. Ensure chassis mounting space accommodates the physical dimensions specified in the technical documentation.
Selection Notes
Select this model when a three-phase filter with low leakage characteristics is required for Delta-connected loads. The 20 A rating suits moderate power applications, while the 220 nF capacitance provides standard attenuation. Verify that the M4 screw terminal interface matches existing wiring harnesses. Consider the chassis mount style for fixed installations where panel integration is necessary.
Part Context
This component belongs to the FN3040 series of three-phase filters from Schaffner. It is part of a broader family of EMC solutions designed for industrial environments. The series typically includes variants with different current ratings and terminal configurations, allowing for scalable deployment across various power levels while maintaining consistent filtering performance standards.
Replacement Considerations
Direct substitutes may include other Schaffner FN3040 series variants with adjusted current or voltage ratings. Cross-reference part numbers such as FN3041 or FN3042 if different terminal styles are needed. Ensure any replacement maintains the same MnZn core characteristics and leakage current limits to preserve system EMC integrity.
