Shop Legrand DX3 MCB 2 Pole 125A Curve C Circuit Breaker | 409777 In Iraq Best Prices
Legrand DX3 modular bipolar thermal-magnetic circuit breaker with 125A C-curve protection, 25kA breaking capacity at 400V, IP20 finger-safe terminals, and DIN-rail mounting for reliable electrical circuit protection.
The Legrand DX³ MCB (Miniature Circuit Breaker) is a high-performance modular bipolar thermal-magnetic circuit breaker designed for residential and small commercial electrical installations. With a rated current of 125A and C-curve protection characteristics, this device delivers exceptional breaking capacity of 25kA at 400V, making it ideal for protecting circuits against overloads and short circuits. The fully visible breaking mechanism ensures safe operation, while the IP20 finger-safe terminals provide enhanced protection against accidental contact. This circuit breaker features DIN-rail mounting for easy installation and copper supply connections, offering flexibility with both top and bottom supply options.
Designed to meet international standards (IEC 60947-2), the DX³ 2-pole breaker incorporates advanced thermal-magnetic tripping technology with a C-curve characteristic suitable for general-purpose circuits with moderate inrush currents. The device is equipped with a red/green mechanical indicator that clearly displays the open or closed status of contacts, along with a convenient label holder for circuit identification. With a built-in depth of 47mm and width of 53.4mm, it occupies minimal DIN-rail space while providing maximum protection. The breaker operates reliably across a wide ambient temperature range of -25°C to +70°C and features halogen-free construction for environmental compliance.
The DX³ breaker is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customized protection solutions. Its robust construction with IK02 impact resistance ensures durability in demanding electrical environments. The device complies with substance-restriction requirements and has been designed through an environmentally conscious manufacturing process, with a carbon footprint of 3.589 kg CO₂ equivalent during the manufacturing phase.
