FSB-20-324-H is listed in the Power Line Filter Modules range at ChipApex. The manufacturer field lists Cosel USA, Inc.. Its product description is LINE FILTER 500VAC 20A CHASS MNT. Review the specifications below when checking this part for your BOM.
The Cosel FSB-20-324-H is a three-phase EMI filter designed for chassis mounting. It supports a continuous current of 20 A at voltages up to 500 VAC. The unit operates within a frequency range of 50/60 Hz and functions reliably in ambient temperatures from -40°C to +85°C. Connection is facilitated via terminal block interfaces, ensuring secure integration into industrial power distribution systems requiring robust electromagnetic interference suppression.
Verify the specific datasheet revision and compliance certifications prior to procurement. Confirm that the terminal block specifications match your wiring requirements. Ensure the thermal environment remains within the specified operating range to maintain performance integrity and safety standards throughout the component lifecycle.
Select this model when a dedicated two-stage EMI solution is required for three-phase delta systems. Consider the 20 A current rating and 500 VAC voltage limit against your system's maximum load conditions. Evaluate the chassis-mount form factor against available panel space and ensure compatibility with existing terminal block infrastructure.
This component belongs to the Cosel FSB series, which specializes in high-performance power line filters. The series is engineered for demanding industrial environments where strict electromagnetic compatibility is essential. These filters are designed to suppress conducted noise, protecting sensitive downstream equipment from electrical disturbances generated by upstream power sources or switching loads.
Consult official Cosel documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' three-phase filters without verifying electrical ratings and physical dimensions.
