Shop Legrand DX3 MCB 2 Pole 20A Circuit Breaker Curve C | 410149 In Iraq Best Prices
Legrand DX3 modular bipolar circuit breaker with 20A rating, C curve protection, 50kA breaking capacity at 400V, IP20 finger-safe terminals, and full DX3 compatibility for residential and commercial applications.
The Legrand DX3 MCB is a modular bipolar thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced device offers exceptional breaking capacity of 50kA at 400V and 100kA at 230V, ensuring reliable protection against short circuits and overcurrent conditions. The C curve tripping characteristic provides optimal protection with a tripping threshold between 100A and 200A (5 In to 10 In), making it ideal for circuits with moderate inrush currents such as lighting and standard loads.
Features include IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, ensuring safe operation in domestic and commercial environments. The device is compatible with DX3 auxiliaries, RCD add-on modules, and various Legrand accessories, allowing for flexible system expansion and customization. The red/green mechanical indicator provides clear visual status indication of whether contacts are open or closed, while the integrated label holder enables convenient circuit identification.
Built to the highest environmental and safety standards, this circuit breaker complies with IEC 60947-2 standards and substance-restriction requirements. It features a 3-module width for DIN rail mounting, operates across 50-60 Hz frequency ranges, and maintains performance in ambient temperatures from -25°C to 70°C. The halogen-free design and environmentally conscious manufacturing process make it an eco-friendly choice for modern electrical installations.
