ERICO CRITEC 20kA Transient Discriminating Filter Surge Diverter TDF3A240V

ERICO CRITEC 20kA Transient Discriminating Filter Surge Diverter TDF3A240V

The TDF series has been specifically designed for process control applications to protect the switched mode power supply units on devices such as PLC controllers, SCADA systems, and motor controllers. Units are UL® Recognized and available for 3A, 10A, and 20A loads, suitable for 110-120V ac/dc and 220-240Vac circuits.

Key Features of the TDF Series:

• Compact design - small footprint
• High efficiency sine wave filtering
• DIN rail mount for easy installation
• Status indication for monitoring
• High surge rating:
  • 50kA (TDF)
  • 8kA (DSF)
• TD technology

The TDF is a series-connected, single-phase surge filter providing an aggregate surge capacity of 50kA (8/20μs) across L-N, L-PE, and N-PE. The low pass filter provides up to 65dB of attenuation to voltage transients.

This not only reduces the residual let-through voltage, but also further reduces the steep voltage rate-of-rise, offering superior protection for sensitive electronic equipment.
