Shop Legrand DX3 2P 16A Curve D Circuit Breaker 409820 | 409820 In Iraq Best Prices
Legrand DX3 2-pole 16A D-curve modular circuit breaker with 25kA breaking capacity at 400V, IP20 finger-safe terminals, and comprehensive protection for residential and small commercial applications.
The Legrand DX3 MCB 2-pole 16A curve D circuit breaker (reference 409820) is a modular thermal-magnetic protection device designed for residential and small commercial electrical installations. This advanced circuit breaker delivers exceptional breaking capacity of 25kA at 400V and 50kA at 230V, ensuring reliable protection against short circuits and overload conditions. The device features a D-curve tripping characteristic with a threshold between 160A and 224A (10-14 times the rated current), making it ideal for circuits with moderate inrush currents such as general purpose loads and lighting circuits.
The DX³ circuit breaker is equipped with fully visible breaking mechanism and IP20 finger-safe terminals, providing both safety and ease of installation. Its compact 2-module width design allows efficient DIN rail mounting with independent removal capability thanks to dual clamps on top and bottom. The breaker can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar systems, offering maximum installation flexibility. With comprehensive labeling capabilities and clear ON/OFF indication markings, this MCB ensures easy circuit identification and status monitoring.
Built to the highest environmental standards, the DX3 circuit breaker is halogen-free and complies with all RoHS and REACH regulations. It operates reliably across a wide ambient temperature range from -25°C to +70°C and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. The product's 1.821 kg CO₂ equivalent manufacturing footprint reflects Legrand's commitment to sustainable electrical solutions.
