Important note

Informacje produktowe
Mode 2: State where the voltage-limiting part of the SPD was short-circuited due to a very low impedance within the SPD. The line is inoperable, but the measuring equipment is still protected by means of a short-circuit.

Tender specification sheets

Long specification
Surge protection in a one piece, 12.4 mm wide terminal rail module for an intrinsically safe, floating-ground signal circuit with 24 VDC in 2-wire technology. A current loop (Ex ia) with max. 0.3 A can be protected here. When the terminal is fitted, a sparkover gap is simultaneously created to the high-impedance earth between the terminal rail (earth) and the reference potential (ground) of the protective circuit. Visual identification of the terminal according to the type of protective circuit and the voltage level. The terminal can be labelled. Suitable for ATEX applications. Tested according to explosion protection types in EX areas: Ex ia IIC / Ex iaD.
