Shop Legrand DX3 MCB 1P 16A Curve D 10kA Circuit Breaker | 409432 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 16A rated current, D-curve characteristic, and 10kA breaking capacity for residential and small commercial installations
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 230/400V AC networks, this single-pole device features a D-curve release characteristic suitable for circuits with moderate inrush currents. Reference number 409432, the MCB can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. The device operates at rated current of 16A with rated voltage of 230V and rated impulse withstand voltage of 4kV, making it ideal for residential and small commercial applications.
This circuit breaker offers advanced protection features including a breaking capacity of 10kA according to IEC 60898-1 standard for household installations, with a tripping threshold in case of short-circuit between 160A and 224A (D curve between 10In and 14In). The MCB is protected against solid bodies larger than 12.5mm (fingerproof) with IP20 protection rating according to IEC/EN 60529 standard. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules and accessories, and can also be connected to aluminium cable with terminal accessory number 4 063 10.
The device features two DIN rail clamps (one top side and one bottom side) for independent removal while the prong busbar remains in place. It includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. Built with halogen-free materials and designed with environmental consciousness, this product complies with substance-restriction requirements. The compact design with dimensions of 17.8mm width, 94.8mm height, and 77.8mm depth fits standard 1-module spacing on DIN rails.
