Single-pole 25A C-curve miniature circuit breaker with 10kA breaking capacity, IP20 protection, and DX3 compatibility for reliable overload and short-circuit protection in residential and commercial installations.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect and control wiring installations against overloads and short-circuits. This single-pole device features a 25A rated current with C curve release characteristic, providing reliable protection for residential and small commercial applications. With a breaking capacity of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2, this MCB delivers superior performance and safety for modern electrical systems.
The breaker incorporates advanced current limiting technology (Class 3) that minimizes let-through energy, ensuring maximum protection of connected equipment. Its IP20 protection rating makes it suitable for flush-mounted installation in standard DIN rail enclosures. The device features a user-friendly design with ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Additionally, it includes a label holder for clear circuit identification and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories.
With a built-in depth of 44mm and width of 17.8mm (1 modular spacing), this compact MCB is ideal for space-constrained installations. The device operates reliably across a wide temperature range from -25°C to +70°C and features halogen-free construction for environmental compliance. It can be supplied through copper cables, prong busbars, fork busbars, or Legrand HX3 plug busbars, offering flexible installation options for various electrical configurations.
