Shop Legrand DX3 MCB 1P 40A D-Curve 10kA Circuit Breaker | 409436 In Iraq Best Prices
Legrand DX3 single-pole 40A D-curve thermal magnetic circuit-breaker with 10kA breaking capacity, IP20 protection, and DIN-rail mounting for reliable electrical installation protection.
The Legrand DX3 MCB 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 40A D-curve rating and 10kA breaking capacity at 230V, this single-pole device provides reliable protection for residential and small commercial applications. The circuit-breaker features IP20 finger-safe protection, DIN-rail mounting with dual clamps for independent removal, and a convenient label holder for circuit identification. Its D-curve characteristic means it trips between 10 and 14 times the rated current during short-circuits, making it ideal for circuits with moderate inrush currents.
This MCB is equipped with advanced features including On/Off indication printed on the handle with red and green backgrounds for easy status identification. The device can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar connections. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for flexible system integration. The product complies with IEC 60898-1 standards for household installations and meets substance-restriction requirements with halogen-free construction.
Installation is straightforward with screwed terminals accommodating solid-core conductors from 1.5-35 mm² and multi-wired conductors from 1.5-25 mm². The device operates reliably across a wide ambient temperature range of -25 to 70°C and features a compact design with dimensions of 17.8mm width, 94.8mm height, and 77.8mm depth. With its robust construction, comprehensive protection capabilities, and ease of integration into existing systems, this Legrand DX3 circuit-breaker is an excellent choice for modern electrical installations.
