The TTC-6-3-HF-M-12DC-UT-I is a surge protection device specifically engineered for high-frequency applications and telecommunications interfaces that do not require a supply voltage. It features an integrated status indicator and a knife disconnection mechanism, allowing for the protection of three signal wires sharing a common reference potential.

This device operates effectively with a nominal voltage of 12 V DC and is capable of handling a rated current of 600 mA at 40 °C. The surge protection device is classified under IEC category C1, indicating its suitability for overvoltage category III and pollution degree 2 environments. It provides a maximum continuous operating voltage of 15 V DC.

In terms of surge handling capacity, the device can manage a nominal discharge current of 5 kA for both line-line and line-ground connections, with a total discharge current capacity of 10 kA. Voltage protection levels are ≤ 145 V for line-line and ≤ 80 V for line-earth, ensuring reliable operation even in demanding conditions.

Designed for installation on a DIN rail (TH 35 - 7.5 mm), this module has an ambient operating temperature range of -40 °C to 85 °C and a degree of protection rated at IP20, making it suitable for various industrial environments. The optical surge protection fault message feature enhances maintenance and operational reliability.
