This surge protection device is specifically designed for a 2-wire floating signal circuit, capable of handling a current loop in the range of 0(4) ... 20 mA. It includes a protective plug and base element, along with an integrated status indicator. The device is classified under the IEC test classification C1 and can be mounted on a DIN rail.

With a nominal voltage of 24 V DC and a maximum continuous operating voltage of 30 V DC, this device ensures reliable operation under various conditions. The surge protection capabilities include a nominal discharge current of 5 kA for both line-line and line-earth configurations, with a total discharge current capacity of 10 kA. The voltage protection levels are ≤ 200 V for line-line and ≤ 750 V for line-earth, ensuring robust protection against voltage spikes.

Constructed from PBT material with a flammability rating of V-0 according to UL 94, the device is suitable for a wide range of environmental conditions, operating effectively within an ambient temperature range of -40 °C to 85 °C. It also features an optical surge protection fault message and requires a maximum back-up fuse of 630 mA (FF). The device meets standards outlined in EN 61643-21.
