imo panel mount rfi filter 3phase, 400v, 15amp category c2
IMO RF15A-4A panel mount EMC/RFI filter for 400 V three-phase variable speed drive applications with a 15 A current rating and Category C2 EMC compliance applications.
Why Choose the IMO RF15A-4A EMC/RFI Filter?
The IMO RF15A-4A is a high performance three-phase EMC/RFI filter designed to reduce conducted electromagnetic interference generated by variable speed drives and industrial power electronics. Manufactured by IMO Precision Controls, it helps equipment comply with EMC requirements while improving the reliability of automation and motor control systems.
Installed between the incoming mains supply and the inverter, the RF15A-4A suppresses high frequency electrical noise that can interfere with PLCs, sensors, communication equipment and other sensitive electronic devices. Its robust panel mounting design makes it ideal for installation inside electrical control panels, machine enclosures and industrial automation cabinets.
With a 15 A current rating, 400 V AC three-phase operation and Category C2 EMC compliance applications, the IMO RF15A-4A is an excellent solution for improving EMC performance in inverter driven machinery, conveyors, pumps, fans and production equipment.

Reliable EMC Protection for Industrial Drive Systems
Variable speed drives generate high frequency switching noise as part of normal operation. An EMC/RFI filter such as the IMO RF15A-4A reduces conducted emissions before they enter the electrical supply, helping improve electromagnetic compatibility and ensuring stable operation of nearby automation equipment.
The RF15A-4A is suitable for industrial machinery where drives, PLCs, sensors and communication equipment operate within the same control cabinet. By minimising electrical interference, it contributes to improved machine reliability and supports compliance with recognised EMC standards.
Typical Applications
- Variable speed drive installations.
- Industrial motor control panels.
- Machine building and OEM equipment.
- Pump and fan control systems.
- Conveyor and material handling systems.
- Production and packaging machinery.
- Industrial automation and control cabinets.
