Shop Legrand DX3 MCB 2P 20A Curve D Circuit Breaker 10kA | 409452 In Iraq Best Prices
Legrand DX3 thermal magnetic 2-pole 20A circuit breaker with D-curve protection, 10kA breaking capacity at 400V, IP20 fingerproof safety, and DIN rail mounting for residential and commercial electrical protection.
The Legrand DX3 MCB 2P 20A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This advanced protective device features a 10kA breaking capacity at 400V and 16kA at 230V, making it ideal for residential and small commercial applications. The D-curve release characteristic provides selective protection with a tripping threshold between 200A and 280A for short-circuit conditions, ensuring reliable operation in diverse electrical environments.
This 2-pole modular circuit breaker offers comprehensive safety features including IP20 fingerproof protection according to IEC/EN 60529 standards, preventing accidental contact with live components. The device features DIN rail mounting with dual clamps for independent removal without disrupting the prong busbar supply. With a rated voltage of 400V and insulation voltage of 500V, it accommodates multi-wired conductors from 1.5-25mm² and solid-core conductors up to 35mm², providing flexible installation options.
The MCB DX3 is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, offering expandability for complex electrical systems. The grey-colored device (RAL 7035) includes a label holder for circuit identification and clear ON/OFF indication on the handle for easy status recognition. Built with halogen-free materials and designed through environmentally conscious processes, this circuit breaker combines performance with sustainability, making it an excellent choice for modern electrical installations.
