Legrand DX3 thermal magnetic circuit-breaker with 3-pole, 50A rating, D curve, 6000A breaking capacity, and IEC 60898-1 compliance for reliable protection and control of residential and commercial wiring installations.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits while providing control and isolation capabilities. With a 3-pole configuration, 50A rated current, D curve characteristic, and 400V~ rating, this device delivers a 6000A breaking capacity according to IEC 60898-1 standards. The circuit-breaker features advanced protection mechanisms including a tripping threshold between 500A and 700A for short-circuit conditions (D curve between 10 In and 14 In), making it ideal for residential and small commercial applications.
This MCB is engineered with multiple supply options including copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standards. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexibility for complex electrical installations. The connection terminals support both multi-wired conductors (1.5-25 mm²) and solid-core conductors (1.5-35 mm²), accommodating diverse installation requirements.
The product features innovative design elements including two DIN rail clamps for independent removal while the busbar remains in place, and a convenient label holder for clear circuit identification. The handle includes on/off indication with red and green backgrounds for easy status identification. With halogen-free construction and environmentally conscious design, this circuit-breaker complies with substance-restriction requirements and RoHS directives, ensuring safe and sustainable electrical installations.
