Legrand DX3 thermal magnetic circuit-breaker with 50kA breaking capacity, 40A rating, C-curve protection for overloads and short-circuits in residential and commercial installations.
The Legrand DX3 MCB 1 Pole 40A Curve C is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With an impressive 50kA breaking capacity at 230V according to IEC60947-2 standards, this device provides reliable protection and control for electrical installations. The circuit-breaker features a C-curve tripping characteristic with a short-circuit tripping threshold between 200A and 400A (5 In to 10 In), making it ideal for general-purpose applications in residential and small commercial settings.
This single-pole, 40-amp rated device offers comprehensive protection features including a red/green mechanical indicator that clearly displays the status of contacts (open or closed), and a convenient label holder for circuit identification. The DX3 is designed with an IP20 degree of protection against solid bodies larger than 12.5mm, ensuring safety in typical indoor environments. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories to enhance functionality and adapt to specific installation requirements.
The product complies with all substance-restriction requirements and has been designed following environmentally conscious manufacturing processes. With a built-in depth of 47mm and dimensions of 26.7mm width by 127.5mm height by 79.2mm depth, it occupies minimal space in distribution panels. The device operates reliably across a frequency range of 50-60Hz and maintains performance across ambient temperatures from -25°C to +70°C, with a storage temperature range of -40°C to +70°C.
