Shop Legrand DX3 MCB 1P+N 4A Curve C Circuit Breaker | 407737 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker with 4A rating, C curve, 6000A breaking capacity, IP20 protection, and DIN rail mounting for residential electrical installations.
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 4A and C curve characteristic, this single pole plus neutral device offers a 6000A breaking capacity at 230V. The breaker features IP20 finger-safe protection, preventing accidental contact with live parts larger than 12.5mm, and is mounted on DIN rails for easy installation and removal. The device incorporates energy limitation class 3 according to IEC 60898-1 standard, ensuring maximum protection and minimal let-through energy during fault conditions.
This MCB is equipped with two DIN rail clamps (top and bottom) allowing independent removal while the prong busbar remains in place. The handle includes ON/OFF indication printed on red and green backgrounds for easy status identification. A label holder is integrated for clear circuit identification. The device can be supplied by copper cable or prong busbar from either the top or bottom side, providing flexible installation options. It is compatible with Legrand DX3 auxiliaries and accessories, making it an integral part of a comprehensive electrical protection system.
The Legrand DX3 MCB complies with IEC 60898-1 standard for household installations and features substance-restriction requirements compliance with environmentally conscious design. Operating temperature range is -25°C to +70°C, with storage capability from -40°C to +70°C. The device supports connectable conductor cross-sections from 0.75mm² to 16mm² for solid-core conductors and 0.75mm² to 10mm² for multi-wired conductors, accommodating various installation requirements.
