The FS234xx family includes Schaffner mains filters designed for interference suppression; the FS23417-36-52DS code is specifically identified in Schaffner product documentation.
⚡ Function in the Electrical System
The filter is installed between the power supply and the equipment, connecting the LINE side to the source and the LOAD side to the load.
Its function is to attenuate high-frequency conducted interference, limiting the propagation of electromagnetic interference along the L/N conductors. It is therefore particularly suitable for electronic equipment, industrial systems, power supplies, converters, and power systems where control of EMC emissions is important.
🔌 Connections
The following markings are clearly shown on the component:
LINE – Grounding Electrode Terminal – L – N – US Sense
The opposite side features:
LOAD – L – N
The original warning is also present:
“The auxiliary conductors are not fused!”
Therefore, the auxiliary conductors must be handled according to the manufacturer's requirements and those of the equipment in which the filter is installed.
🏭 Construction and Condition
The filter is constructed with a robust metal enclosure, power terminal block, and auxiliary connections. The photographs show normal signs of previous installation, small scratches, and slight superficial marks on the metal structure.
The component is sold as used; electrical functionality is not declared unless it has been subjected to specific testing.
🌐 Applications
Suitable for:
- industrial power supplies and equipment
- power electronics
- conversion systems
- industrial machinery
- equipment where it is necessary to reduce EMC/RFI interference on the AC mains
- replacement of equivalent Schaffner filters, subject to verification of voltage, current, and connection configuration.
🛡️ Safety
The component operates at 230 VAC / 36 A: installation must only be carried out by qualified personnel, with the equipment completely disconnected from the power supply.
It is necessary to respect the correct distinction between LINE and LOAD, the L/N connections, the earth/PE connection, and the specifications concerning the auxiliary conductors, which are not fused.
