Shop Legrand DX3 MCB 1 Pole 40A Curve D Circuit Breaker | 409811 In Iraq Best Prices

Thermal-magnetic 1-pole 40A circuit breaker with 25kA breaking capacity, D-curve tripping, IP20 rated protection, and modular design for residential and commercial electrical installations

The Legrand DX3 MCB 1 Pole 40A Curve D is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a rated breaking capacity of 25kA at 230V according to IEC 60947-2 standards, this device provides reliable protection for residential and small commercial applications. The circuit breaker features a D-curve tripping characteristic with a short-circuit tripping threshold between 400A and 560A (D curve between 10 In and 14 In), making it ideal for circuits with moderate inrush currents. This single-pole modular circuit breaker is equipped with a red/green mechanical indicator that clearly displays the open or closed status of the contacts, along with a label holder for convenient circuit identification. The device is IP20 rated (fingerproof protection against solid bodies larger than 12.5mm) and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. It operates at a rated voltage of 230V AC with a rated insulation voltage of 500V and impulse withstand voltage of 6kV. The MCB features a built-in depth of 47mm and occupies 1.5 modular spacings, making it compact for panel installation. It accepts connectable conductor cross-sections from 1.5-35mm² for multi-wired cables and 1.5-50mm² for solid-core cables. The device operates reliably across temperatures from -25°C to 70°C and is designed with environmental consciousness, complying with substance-restriction requirements and following an environmentally conscious manufacturing process.
