High-performance 3-pole 40A modular circuit breaker with 50kA breaking capacity, D-curve protection, IP20 rating, and flexible installation options for residential and commercial applications.
The Legrand DX3 MCB 3 Pole 40A Curve D Circuit Breaker is a high-performance modular circuit breaker designed for residential and small commercial electrical installations. With a breaking capacity of 50kA according to IEC 60947-2 standards, this device provides reliable protection against short circuits and overloads with a tripping threshold between 400A and 560A. The D-curve characteristic makes it ideal for circuits with moderate inrush currents, offering protection for general purpose applications.
This circuit breaker features advanced safety characteristics including IP20 protection rating against solid bodies larger than 12.5mm, ensuring fingerproof operation. The device is equipped with a red/green mechanical indicator that clearly displays the open or closed status of contacts, and includes a label holder for easy circuit identification. It can be supplied by copper cable from either the top or bottom side, providing flexible installation options. The DX3 can be equipped with Legrand's range of auxiliaries, RCD add-on modules, and accessories for enhanced functionality.
Built with environmentally conscious design principles and halogen-free materials, the DX3 complies with substance-restriction requirements. The compact design with a built-in depth of 47mm and width of 80.1mm allows for efficient panel space utilization. Operating across a wide temperature range from -25°C to 70°C, this circuit breaker maintains reliable performance in various climatic conditions. The DX3 is suitable for DIN rail mounting and accepts both solid-core and multi-wired conductors from 1.5 to 50mm².
