Shop Legrand DX3 Three-Pole 16A Curve C Circuit Breaker | 410021 In Iraq Best Prices
Professional three-pole 16A circuit breaker with 36kA breaking capacity, C-curve protection, IP20 finger-safe design, DIN-rail mounting, and full compatibility with Legrand DX3 accessories for reliable electrical protection.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a professional-grade three-pole modular thermal-magnetic circuit breaker designed for residential and small commercial electrical installations. With a breaking capacity of 36kA at 400V~, this device provides reliable protection against overcurrent and short-circuit faults. The C-curve protection characteristic at 16A rating makes it ideal for circuits with moderate inrush currents typical of lighting and general-purpose loads.
This circuit breaker features fully visible breaking mechanism with a red/green mechanical indicator that clearly displays the status of contacts (open or closed), ensuring safe operation and easy circuit identification. The IP20 finger-safe design protects against accidental contact with live parts, while the DIN-rail mounting system allows for quick and secure installation in electrical panels. The device is constructed from high-quality materials and complies with IEC 60947-2 standards, ensuring long-term reliability and safety in demanding electrical environments.
The DX³ series is compatible with Legrand's extensive range of auxiliaries, RCD add-on modules, and accessories, allowing for flexible system expansion and customization. With a built-in depth of 47mm and a modular width of 4.5 spaces, this breaker integrates seamlessly into standard electrical distribution boards. The product is halogen-free and has been designed with environmental consciousness, featuring a carbon footprint of 5.433 kg CO2 equivalent during the manufacturing phase.
