4. Carry out Earthing and Short-Circuiting – EaS Devices

Phase Connecting Elements for Switchgear Installations
• To be fitted to the phase cable end of single-pole to five-pole
earthing and short-circuiting devices
• Anti-rotation element PK1
• Other earthing and short-circuiting devices can be configured
online via the earthing and short-circuiting configurator

General Information:
EN/IEC 61230 (DIN VDE 0683-100),
Standard
threaded T pin shaft DIN 48087
Temperature range –25 °C ... +55 °C Connecting the phase cable end with universal clamp to a fixed ball point
Material (clamp body) Cu alloy/gal Sn
Material (terminal lug) Cu alloy/gal Sn
Material (shaft) Cu alloy/gal Sn
Material (pressure plate) Cu alloy/gal Sn / St/Zn Two types of ball head caps are available:
• Rigid ball head cap
• Adjustable ball head cap (4x 90°)
The adjustable ball head cap allows the user to connect the earthing and
short-circuiting device to fixed ball points that are installed in unfavour-
able positions. Thus, in the vast majority of cases, angled fixed ball points
no longer have to be used.

SK: Hexagon shaft

SQ: T pin shaft (bayonet locking mechanism)
