Professional 3-pole thermal magnetic circuit-breaker with 2A B-curve, 6kA/10kA breaking capacity, IP20 protection, and DIN rail mounting for reliable electrical installation protection.
The Legrand DX3 MCB 6000A is a professional-grade thermal magnetic circuit-breaker designed to protect and control wiring installations against overloads and short-circuits. This 3-pole device operates at 400V~ with a rated current of 2A and features a B-curve tripping characteristic, making it ideal for residential and small commercial panel applications. With a breaking capacity of 6kA/10kA and IP20 fingerproof design, this circuit-breaker provides reliable protection with maximum energy limitation (class 3 according to IEC 60898-1 standard).
This MCB features advanced safety and installation capabilities including DIN rail mounting with dual clamps for independent removal, compatibility with Legrand DX3 auxiliaries and RCD add-on modules, and support for multiple supply methods including copper cables, prong busbars, fork busbars, and Legrand HX3 plug busbars. The device includes a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition. Built with halogen-free materials, this product complies with environmental and substance-restriction requirements.
The DX3 MCB is engineered for professional installation in compliance with electrical installation rules and is recommended to be installed by qualified electricians. It offers exceptional reliability with a rated insulation voltage of 500V, rated impulse withstand voltage of 4kV, and operates efficiently across 50-60Hz frequencies. The device is protected against solid bodies larger than 12.5mm and can be equipped with various Legrand accessories for enhanced functionality and customization.
