Industrial FMW4-65-20 Three-Phase EMI Line Filter

Description:

The TIMONTA FMW4-65-20 Three-Phase Filter is used compact single-stage EMC/EMI line filter designed to suppress conducted electrical noise on three-phase AC power systems with a neutral conductor. It is commonly installed in variable frequency drives, stepper motor drives, UPS systems, inverters, and industrial automation equipment to improve electromagnetic compatibility and power quality. Maintenance technicians, panel builders, and OEMs use this filter for new installations, system upgrades, replacement of failed filters, and EMC compliance in industrial electrical systems.

Applications:

The TIMONTA FMW4-65-20 is used in industrial control panels, frequency converters, motor drive systems, UPS equipment, power inverters, and other three-phase electrical installations where conducted EMI suppression is required. Its compact design makes it well suited for space-constrained control cabinets while maintaining reliable noise filtering performance.
