Shop Legrand DX3 MCB 1 Pole 20A D-Curve Circuit Breaker | 410188 In Iraq Best Prices
Legrand DX3 thermal-magnetic circuit breaker with 1 pole, 20A capacity, D-curve characteristic, 50kA breaking capacity, IP20 protection, and compatibility with DX³ auxiliaries for reliable wiring protection.
The Legrand DX3 MCB 1 Pole 20A D-Curve Circuit Breaker (Reference 410188) is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short-circuits. This high-performance device features a 50kA breaking capacity at 230V, making it suitable for residential and small commercial applications. The D-curve characteristic provides optimal protection with a tripping threshold between 200A and 280A (10-14 times the rated current), ensuring reliable protection without nuisance trips.
This circuit breaker is equipped with IP20 fingerproof protection according to IEC/EN 60529 standards, preventing accidental contact with live parts. The 1.5-module width design allows for space-efficient installation in DX³ distribution boards. The device features a red/green mechanical indicator that clearly displays the status of the contacts (open or closed), and includes a label holder for convenient circuit identification. It can be supplied by copper cable from either the top or bottom side and is compatible with DX³ auxiliaries and RCD add-on modules.
The product complies with substance-restriction requirements and has been designed with environmental consciousness in mind. Operating at a rated voltage of 230V AC with a rated insulation voltage of 500V, this circuit breaker is suitable for ambient temperatures ranging from -25°C to 70°C. It accommodates solid-core conductors from 1.5-50mm² and multi-wired conductors from 1.5-35mm², providing flexibility in installation. The device carries a carbon footprint of 1.459 kgCO₂eq during the manufacturing phase, reflecting Legrand's commitment to environmental responsibility.
