Siemens 1P6SN1111-0AA0-1AA1 Line Filter Assembly

Siemens 1P6SN1111-0AA0-1AA1 Line Filter Assembly is a dedicated EMI/RFI noise filter designed for Siemens UI module drive systems. As part of the Siemens 6SN1111 line-filter family, it suppresses high-frequency conducted emissions on input lines, helping drive configurations meet EMC requirements in industrial environments. The assembly provides passive filtering to limit interference from switching devices into sensitive electronics and to reduce conducted noise on supply and control wiring. Typical applications include Siemens drive configurations and modular control panels where maintaining clean power and predictable performance is essential.
