For the maximum 95mm2 conductor, a torque of approximately 10 to 12 Nm is specified by the manufacturer to ensure a secure and low-resistance connection. Always use a calibrated torque screwdriver or wrench.Is this terminal block suitable for use with aluminum conductors?No, this specific Viking 3 terminal block (037170) is designed and certified for use with copper (Cu) cables only. Using aluminum conductors can lead to galvanic corrosion and connection failure over time. For aluminum wires, you must use a terminal block specifically rated for Al/Cu connections.What does the ATEX rating ‘Ex e II 2 G D’ signify?This ATEX marking indicates the block is suitable for hazardous environments. ‘Ex e’ means ‘Increased Safety’ protection for gas atmospheres. ‘II’ is the equipment group for surface industries (not mining). ‘2’ is the equipment category, for zones 1 (gas) and 21 (dust). ‘G’ stands for Gas and ‘D’ for Dust, meaning it is certified for both types of explosive atmospheres.profideals is not an authorized distributor, reseller or representative of the products featured on this website.
