Shop Legrand DX3 MCB 4 Pole 100A Curve C Circuit Breaker | 409802 In Iraq Best Prices
Professional-grade 4-pole 100A circuit breaker with C curve characteristic, 25kA breaking capacity, fully visible breaking mechanism, and IP20 finger-safe terminals for residential and commercial electrical protection.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a four-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits. With a rated current of 100A and C curve characteristic, this device provides reliable circuit protection with a breaking capacity of 25kA at 400V. The breaker features fully visible breaking mechanism, allowing users to clearly see the status of contacts through the red/green mechanical indicator. This professional-grade component is engineered to meet IEC 60947-2 standards and offers IP20 finger-safe terminals, making it suitable for installation in residential and small commercial electrical panels.
Equipped with advanced safety features, the DX³ 100A breaker includes a label holder for clear circuit identification and concurrently switches the neutral conductor for enhanced safety. The device can be supplied by copper cable from either the top or bottom, providing installation flexibility. With a rated voltage of 400V and rated insulation voltage of 500V, this circuit breaker is designed for AC applications with frequencies between 50-60 Hz. The thermal-magnetic tripping mechanism ensures protection against both overload and short-circuit conditions, with the C curve providing a tripping threshold between 500A and 1000A (5 In to 10 In).
The Legrand DX³ 100A circuit breaker is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and accessories, allowing for system expansion and customization. Built with halogen-free materials and designed through an environmentally conscious process, this product complies with substance-restriction requirements. The breaker operates reliably in ambient temperatures ranging from -25°C to 70°C and can accommodate multi-wired conductors from 6-50mm² or solid-core conductors from 6-70mm². Its compact design with a built-in depth of 47mm and width of 106.8mm makes it ideal for space-constrained installations.
