Single-pole thermal magnetic circuit-breaker with 20A C-curve, 6kA breaking capacity, IP20 protection, and energy limitation class 3 for residential and commercial electrical installations
The Legrand DX3 MCB 6000A 1 pole 20A curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 6kA at 230V, this device offers reliable protection for residential and small commercial applications. The circuit-breaker features a C-curve tripping characteristic with a short-circuit threshold between 100A and 200A (5-10 times the rated current), making it suitable for general purpose circuits with moderate inrush currents. It provides IP20 finger-safe protection and achieves energy limitation class 3 according to IEC 60898-1 standards, ensuring maximum safety and performance.
This single-pole MCB is equipped with two DIN rail clamps (top and bottom) allowing independent removal while the busbar remains in place. 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). It features a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. The breaker is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories.
With a compact design measuring 17.8mm width and 44mm built-in depth, this MCB fits efficiently into standard DIN rail installations. The device operates reliably across temperatures from -25°C to +70°C and can accommodate conductor cross-sections from 1.5mm² to 35mm² (solid-core) or 1.5mm² to 25mm² (multi-wired). It complies with substance-restriction requirements and has been designed with environmental consciousness, featuring halogen-free materials and a carbon footprint of 0.754 kgCO₂eq during the manufacturing phase.
