Industrial-grade 400A three-pole changeover switch with moulded case design, IEC EN 60947-3 compliant, featuring self-wiping knife contacts, dual break points, and comprehensive circuit protection for distribution board installation.
The Legrand DCX-M changeover switch is a premium industrial-grade switching device designed for heavy-duty applications requiring reliable power distribution and circuit protection. This Size 3 model features a robust 400A rated permanent current capacity with exceptional performance under demanding conditions. Built with moulded case design incorporating non-flammable glass fibre reinforced polyester construction, it delivers superior mechanical and electrical track resistance combined with low water absorption properties. The device features knife-type contacts with self-wiping action that maintain optimal contact pressure even under heavy starting currents or short-circuit conditions, ensuring shock and vibration-proof operation with four breaking points per pole and two double-break contacts for enhanced safety and reliability.
This three-pole changeover switch is specifically engineered to function as a main switch, maintenance/service switch, safety switch, and reversing switch. With a maximum rated operation voltage of 800V AC and rated operating voltage range of 400-1000V, it delivers 125 kW operation power at AC-23 400V. The long rotary handle (I-O-II) provides intuitive manual control, while the bolt connection type ensures secure and permanent electrical connections. The device is specifically designed for distribution board installation with IP2X front-side protection rating, making it ideal for industrial control panels and electrical distribution systems.
Compliant with IEC EN 60947-3 standards, this changeover switch incorporates two normally closed auxiliary contacts and two normally open auxiliary contacts for comprehensive circuit monitoring and control flexibility. The conditioned rated short-circuit current of 12 kA provides excellent protection against electrical faults, while the rated short-time withstand current of 13 kA ensures durability during transient conditions. Black control element with professional industrial design makes it suitable for diverse industrial applications including motor control, load switching, and emergency power distribution scenarios.
