Shop Legrand DX3 MCB 1 Pole 25A Curve D Circuit Breaker | 410189 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker, 1 pole, 25A rated current, D-curve characteristic with 50kA breaking capacity, IP20 protection, ideal for residential and commercial electrical installations with reliable overload and short-circuit protection.
The Legrand DX3 MCB 1 Pole 25A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This device features a 50kA breaking capacity at 230V according to IEC 60947-2 standards, making it suitable for residential and small commercial applications. The D-curve tripping characteristic provides optimal protection with a tripping threshold between 250A and 350A (10-14 times the rated current), ensuring safe operation and precise fault detection.
This single-pole circuit breaker is equipped with a red/green mechanical indicator that clearly displays the open or closed status of the contacts, along with a convenient label holder for circuit identification. The device is fingerproof with IP20 protection rating according to IEC/EN 60529 standard, preventing accidental contact with internal components. It can be supplied by copper cable from the top or bottom side and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.
The MCB DX3 is built with environmentally conscious design principles and complies with substance-restriction requirements. With a built-in depth of 47mm and modular width of 1.5 spacings, it integrates seamlessly into standard electrical panels. The device operates reliably across a wide ambient temperature range from -25°C to 70°C and can accommodate multi-wired conductors from 1.5-35mm² or solid-core conductors from 1.5-50mm². Optional equipment can be added for extended functionality, making this circuit breaker a versatile solution for modern electrical installations.
