FTB-80-203-S

Power Line Filter Modules Overview

The FTB-80-203-S is a three-phase (Wye) EMC/EMI power line filter module manufactured by Cosel USA, Inc. It features an 80 A current rating and a 500 VAC voltage rating, designed for operation at 50/60 Hz frequencies. The unit utilizes a two-stage terminal block connection method and is constructed for chassis mounting. This high attenuation filter is part of the FT series and includes a capacitance value of 20 nF with a leakage current of 1 mA. It operates within a frequency range of 150 kHz to 1 MHz.

Power Line Filter Modules Feature Summary

• Provides two-stage EMI/EMC filtering for three-phase Wye systems
• Utilizes screw terminal block connections for secure wiring
• Designed for direct chassis mounting installation

Power Line Filter Modules Applications

• Industrial power conditioning systems
• Three-phase motor drive protection
• Heavy machinery power supply filtering

Power Line Filter Modules Procurement Notes

Verify the specific suffix 'S' against official Cosel documentation to confirm terminal block configuration. Ensure chassis mounting dimensions align with enclosure specifications. Confirm that the 80 A continuous current rating meets system load requirements without derating issues under ambient operating conditions.

Power Line Filter Modules Selection Notes

Select this model for applications requiring robust three-phase filtering in Wye configurations. Compare the 80 A rating against peak and continuous loads. Consider the chassis mount style for fixed installations where space constraints allow for panel integration. Verify compatibility with existing terminal block wiring practices.

Power Line Filter Modules Part Context

This component belongs to the Cosel FT series of power line filters, which are engineered for industrial environments. The FTB sub-series specifically addresses high-current three-phase applications. These modules are distinct from single-phase counterparts and offer specialized attenuation characteristics for complex electromagnetic interference scenarios in heavy-duty power distribution networks.

Power Line Filter Modules Replacement Considerations

Consult official Cosel cross-reference lists for verified substitutes. Generic equivalents may not match the two-stage terminal block design or specific Wye configuration requirements. Ensure any replacement maintains the 500 VAC and 80 A ratings to prevent system failure.
