Industrial-grade DCX-M changeover switch with 1250A capacity, moulded case design, knife-type contacts with self-wiping action, 3-pole configuration, IEC EN 60947-3 compliant for reliable power distribution and circuit protection.
The Legrand DCX-M changeover switch is a premium industrial-grade switching solution designed for heavy-duty applications requiring reliable power distribution and circuit protection. This Size 5 model features a robust moulded case design with frame parts constructed from non-flammable glass fibre reinforced polyester, providing exceptional mechanical and electrical track resistance with minimal water absorption. The device is specifically engineered for switching operations up to 1250A at rated permanent current, making it ideal for large industrial installations, power distribution systems, and critical infrastructure applications.
This changeover switch incorporates advanced knife-type contacts with self-wiping action on contact surfaces, ensuring superior performance under demanding conditions. The design includes four breaking points per pole with two double-break contacts, providing enhanced safety and reliability during switching operations. Under heavy starting currents or short-circuit conditions, the contact pressure automatically increases, while the shock and vibration-proof contact design ensures consistent performance in harsh industrial environments. The device is fully compliant with IEC EN 60947-3 standards and can function as a main switch, maintenance/service switch, safety switch, or reversing switch.
With a maximum rated operation voltage of 1000V AC and a rated short-time withstand current of 25kA, this changeover switch delivers exceptional performance for industrial power management. The long rotary handle provides intuitive operation with I-O-II positioning, allowing for smooth and reliable switching between circuits. The bolt connection system ensures secure and reliable electrical connections, while the IP2X degree of protection on the front side provides adequate safety for distribution board installation.
