Clamping two conductors in Ex applications For the terminals from our W-series, it is normally permitted connect two wires per clamping position long as this permitted accordance with the type test according IEC 60947-7-1 or 60947-7-2.5  24  20. Installation The general statements regarding standard applications are also valid for Ex applications.

Where necessary, end plates or partitions must installed as described ensure adherence to creepage and clearance distances for Ex applications.87. The continuous operating temperature to 60079-0 for the material KRG is 130 °C, for Wemid 120 and for the material °C. the operating current must reduced factor 0. Taking into account further safety factor according 60079-0, we reach the following definitions: Temperature class Ambient temperature T6 -50 +40 °C T5 -50 +55 °C The permitted nominal current must be reduced accordingly the actual ambient temperature higher.4 452 The current-carrying capacity cables and lines the installation defined VDE 0298 part normal ambient temperature °C.ATEX terminal blocks Design for i Terminals for intrinsically-safe circuits (“i“) are passive components.225  15   2.

Certified for the European Directive 94/9/EG ATEX – Electrical data The values for current-carrying capacity as stated the catalogue are based on an ambient temperature 40°C.

Accessories The accessories listed can used and included the ATEX certification. When loaded with the rated current 10%, the temperature the current bar of the modular terminal may not rise more than K. particular, the i requirements always apply the entire circuit, i. Therefore, for use intrinsically-safe circuits, you not need EC-standard examination certificate.67  36  10  57  49.87  88  35 125 108
