Thermal magnetic 2-pole 6A circuit breaker with C-curve, 16kA breaking capacity, IP20 protection, and energy limitation class 3 for residential installations
The Legrand DX3 MCB 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 2-pole device features a 6A rated current with C-curve release characteristic and delivers exceptional 16kA breaking capacity at 230V and 10kA at 400V. The breaker provides IP20 finger-safe protection and energy limitation class 3, making it ideal for residential and small commercial panel applications. Built with precision engineering, it can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections.
This circuit breaker incorporates advanced safety features including thermal and magnetic protection mechanisms that respond instantly to overload and short-circuit conditions. The device 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 unit complies with IEC 60898-1 standards and offers maximum energy limitation for enhanced protection of connected equipment.
The DX3 MCB is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexible installation options for modern electrical systems. With its halogen-free construction and environmentally conscious design, this breaker meets substance-restriction requirements and represents a sustainable choice for electrical protection. Operating temperature range of -25°C to +70°C ensures reliable performance in diverse environmental conditions.
