Thermal magnetic 3-pole circuit-breaker with 10A rated current, 6kA breaking capacity, C-curve tripping, and IP20 protection for residential and commercial installations
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional performance and reliability. This 3-pole device features a rated current of 10A and delivers a 6kA breaking capacity at 400V~, with advanced 10kA breaking capacity according to IEC 60947-2 standards at 400V. The MCB offers C-curve tripping characteristics that provide optimal protection for general purpose circuits, with a tripping threshold between 50A and 100A for short-circuit conditions. With IP20 protection rating, this device is fingerproof against solid bodies larger than 12.5mm, ensuring safe operation in residential and small commercial installations.
This circuit-breaker features a robust construction with two DIN rail clamps positioned on both top and bottom sides, allowing independent removal even when the busbar supplying the row remains in place. The device can be supplied through multiple connection methods including copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). It incorporates energy limitation class 3 according to IEC 60898-1 standard, providing maximum protection against transient overvoltages and fault conditions.
The Legrand DX3 MCB is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, offering flexibility for complex installation requirements. The device operates reliably across ambient temperatures from -25°C to +70°C and features a label holder for clear circuit identification. Built with halogen-free materials and designed through an environmentally conscious process, this circuit-breaker complies with all substance-restriction requirements and represents a sustainable choice for modern electrical installations.
