The Siemens 3RT29161JJ00 Mains Interference Filter is designed for electrical engineers and technicians working with Size S00 contactor relays and motor contactors. Its key benefit is protecting sensitive equipment from voltage surges and electrical noise, ensuring stable operation. A potential caveat is its specific voltage range compatibility. This filter utilizes a varistor with an integrated LED indicator to suppress voltage spikes and reduce electromagnetic interference in AC and DC circuits.

The primary function is to protect contactor relays and motor contactors from voltage surges and transient overvoltages, thereby preventing damage and ensuring stable operation.
It supports 24-48V AC at 50/60 Hz and 12-24V DC.
The integrated LED indicator provides a visual status. If the LED is lit, the suppressor is operational. If it is off, check the wiring and voltage supply.
No, this specific model (3RT29161JJ00) is designed exclusively for Siemens Size S00 contactor relays and motor contactors.
It is effective against voltage surges and transient overvoltages. For specific high-frequency interference, other suppression methods might be necessary.
No, the varistor is an integrated component and is not designed to be user-replaceable. The entire filter unit should be replaced if it fails.
The manufacturer part number is 3RT2916-1JJ00.
Verify that the filter is correctly wired in parallel with the contactor coil and that the coil is receiving the correct operating voltage (within 24-48V AC or 12-24V DC range).
Double-check the wiring connections to ensure they are secure and correctly placed on the filter terminals. Confirm the voltage supply matches the filter's specifications.
Ensure the filter is the correct type for the observed interference. Check for any loose connections or potential grounding issues in the overall system. Consider if the interference frequency exceeds the filter's capabilities.
Setup: The 3RT29161JJ00 is designed to be directly mounted onto Siemens Size S00 contactor relays and motor contactors. Ensure the power to the circuit is completely switched off before installation. Connect the filter terminals in parallel with the coil of the contactor, observing correct polarity for DC applications.
Compatibility: This filter is specifically designed for Siemens Size S00 contactor relays and motor contactors. It operates reliably within a rated voltage of 24-48V AC at 50/60 Hz and 12-24V DC. Always verify that your application's voltage and current ratings are within the specified limits.
Care: The filter requires minimal maintenance. Periodically check the LED indicator to ensure it is functioning correctly. Keep the filter clean and free from dust and debris. In harsh environments, ensure the enclosure provides adequate protection. No user-serviceable parts are inside.
