Legrand DX3 thermal magnetic circuit-breaker with 4-pole, 63A, C curve, 6kA breaking capacity, IP20 fingerproof design, and advanced energy limitation for reliable electrical protection
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device operates at 400V~ with a rated current of 63A and features a C curve characteristic, providing reliable protection for residential and small commercial applications. The circuit-breaker offers a 6kA breaking capacity according to IEC 60898-1 standard with energy limitation class 3, ensuring maximum protection against electrical faults. With its fingerproof IP20 design, the device meets international safety standards and can be safely installed in various environments.
This MCB features advanced technical specifications including a breaking capacity of 6kA at 400V and up to 10kA according to IEC 60947-2 standards. The tripping threshold for short-circuits ranges between 315A and 630A (C curve between 5In and 10In), providing precise protection tailored to installation requirements. The device can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), offering flexible installation options.
The DX3 MCB is equipped with two DIN rail clamps allowing independent removal while the prong busbar remains in place. It features a label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds for easy status identification. The device is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, and can be connected to aluminum cables with optional terminal accessories. Built with halogen-free materials and designed through an environmentally conscious process, this circuit-breaker meets all substance-restriction requirements and RoHS compliance.
