■
Overview
The high-current terminals cover cross-sectional areas from
16 to 240 mm². A reliable cable connection is ensured through
effective design measures, such as:
• Three-point centering of the conductor in the prismatic sleeve
base
• Low contact resistance of the contact area through grooved
surface
• Screw locking through spring-loaded elements
• Terminals enclosed at both ends.
The terminals have an insulating enclosure made of
polyamide 6.6.
The terminals are available in gray and blue.
8WH labeling plates must be used for inscription purposes.
For terminals with terminal sizes up to 95 mm², green-yellow PE
terminals are available.
Mounting on support rails according to IEC 60715.
Note: For flat terminals with terminal bolts, see section Flat terminals.
