Short-circuit chain 70mm2 1x1500mm + 2x600mm and 1x550mm

Product Overview

This three-pole earthing and short-circuiting device (Dreipolig) from HORSTMANN is a portable unit designed for temporary earthing and short-circuiting of disconnected AC systems in accordance with IEC 61230 (VDE 0683-100). The device uses highly flexible copper stranded wires with transparent plastic sheathing and features a transparent casting that allows for visual inspection of the connection.

Construction and Components

• Three short-circuit conductors and one earthing conductor with cable lugs.
• Highly flexible copper stranded wires with transparent plastic sheathing.
• Transparent sealing/casting in the connection piece for visual inspection.
• Phase-side connections: universal phase clamps (for this variant).

Typical Applications

This three-pole device is used for temporary earthing and short-circuiting of all three phases in one working step. According to manufacturer information, it is intended for use by service technicians and maintenance personnel and is suitable for operations where all three phases must be earthed simultaneously, for example, during maintenance work on transformers and switchgear (schaltanlagen). The product's design aims to reduce the time required to establish earthing on all three phases during inspection or maintenance operations.
