Specifications
The document outlines specifications for earthing and short-circuiting devices, focusing on the calculation of required cable or bar cross-sections based on maximum initial short-circuit alternating current (Ik) and short-circuit time (Tk). It references standards such as DIN VDE 0102 and provides a table for maximum short-circuit currents for various cable cross-sections.

Procedures
Instructions are provided for carrying out earthing and short-circuiting using EaS devices. It emphasizes the importance of using cables with identical lengths and cross-sections and installing devices directly next to each other to ensure safety and efficiency.

Norms and Standards
The document adheres to standards such as EN/IEC 61230 (DIN VDE 0683-100) and DIN 48088-1, ensuring compliance with international safety and performance guidelines.

Recommendations
Recommendations include ensuring that earthing and short-circuiting devices are only loaded once with permissible short-circuit currents and maintaining cable lengths as short as possible to minimize movement during short-circuits.

Key Data from Tables
The document includes a table showing the maximum short-circuit current (Ik) for different cable cross-sections and durations, ranging from 16 mm² to 150 mm², with corresponding currents for durations of 10s, 5s, 2s, and 1s.

Product Information
Detailed product information is provided, including part numbers, dimensions, and prices for various components such as fixed ball points, threaded pins, and connectors. The document also specifies materials used, such as E-Cu/gal Sn and StSt A2-70, and provides tightening torque values for different thread sizes.
