Professional industrial changeover switch with 800A capacity, moulded case design, knife-type contacts with self-wiping action, suitable for main switch, maintenance switch, and reversing switch applications.
The Legrand DCX-M changeover switch size 4 is a professional-grade electrical switching device designed for industrial and commercial applications. This moulded case changeover switch features a robust construction with non-flammable glass fibre reinforced polyester frame parts, ensuring high mechanical and electrical track resistance combined with low water absorption. The device is specifically engineered to handle demanding switching operations with rated permanent current of 800A at AC-21, 400V, making it suitable for heavy-duty industrial environments.
This changeover switch incorporates advanced knife-type contacts with self-wiping action on contact surfaces, which significantly enhances performance under heavy starting currents and short-circuit conditions. The contact pressure automatically increases when subjected to extreme electrical stress, ensuring reliable operation. With four breaking points per pole featuring two double-break contacts, the switch provides exceptional safety and operational reliability. The device is rated for maximum operation voltage of 1000V AC with a conditioned rated short-circuit current of 20kA, making it compliant with IEC EN 60947-3 standards.
The switch features a long rotary handle control element with I-O-II position marking, allowing intuitive operation and clear indication of switch status. It is equipped with 2 normally closed auxiliary contacts and 2 normally open auxiliary contacts, providing flexible integration with control systems. The device is suitable for use as a main switch, maintenance/service switch, safety switch, and reversing switch, offering versatile functionality for complex electrical installations. With bolt connection type for the main circuit and IP2X degree of protection on the front side, this switch ensures secure installation and reliable performance in distribution board applications.
