FAQ

The recommended tightening torque varies with the wire size used. 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.

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.

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.
