Shop Legrand DX3 MCB 4 Pole 20A Curve D Circuit Breaker | 410227 In Iraq Best Prices
Premium four-pole thermal-magnetic circuit breaker with 50kA breaking capacity, D-curve 20A protection, IP20 finger-safe terminals, and DIN rail mounting for reliable electrical circuit control and protection.
The Legrand DX3 MCB is a four-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced protective device offers exceptional breaking capacity of 50kA at 400V~, making it ideal for demanding electrical installations. The D-curve 20A tripping characteristic ensures reliable protection against overloads and short circuits, with a tripping threshold between 200A and 280A (D curve between 10 In and 14 In). The device features IP20 finger-safe terminals that prevent accidental contact with live parts, ensuring enhanced safety in installation environments.
Designed with user convenience in mind, the DX3 circuit breaker includes a red/green mechanical indicator that clearly displays the open or closed status of the contacts. The product features a label holder for clear circuit identification, making maintenance and troubleshooting easier. It can be supplied by copper cable from either the top or bottom side, and is compatible with aluminium cables when using the optional terminal accessory. The device is equipped with a 47mm built-in depth and occupies 6 modular spacings on standard DIN rails, making it suitable for compact panel installations.
This circuit breaker complies with IEC 60947-2 standards and is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories. It operates reliably across a wide ambient temperature range of -25°C to 70°C and features halogen-free construction for environmental compliance. The product has been designed with substance-restriction requirements in mind and follows an environmentally conscious manufacturing process, with a carbon footprint of 6.899 kg CO2 equivalent during the manufacturing phase.
