Weidmuller 8953610000

This surge protection module operates at a rated voltage of 24 V and a maximum current of 350 mA, complying with IEC 61643-21 and IEC 62305 standards. The device features a two-stage protection mechanism, ensuring the safety of intrinsically safe circuits in hazardous environments.

With a compact design measuring 17.8 mm in width, 90 mm in height, and 69 mm in depth, this module is suitable for various applications requiring protection against overvoltage and transients. The device employs temperature-controlled varistors for cross protection among active lines and provides optical indication of defects along with temperature monitoring.

It is classified under ATEX and IECEx standards for use in explosive atmospheres, with appropriate ratings for gas and dust protection. The temperature class ratings range from T4 (135°C) to T6 (85°C), ensuring functionality across a broad temperature range of -40 °C to +70 °C.

Furthermore, the surge protection module is designed for pluggable connections in the VSPC BASE system, enhancing installation convenience and reliability. The internal capacitive and inductive values are optimized to minimize signal distortion while maintaining effective protection levels.

For operational integrity, the device has a high mean time to failure (MTTF) of 2,537 years and a safety factor of 95.67%, ensuring long-term reliability in demanding environments.
