Shop Legrand DX3 MCB 3 Pole 50A Circuit Breaker Type C | 407864 In Iraq Best Prices
Thermal magnetic 3-pole 50A circuit breaker with 10kA breaking capacity, C-curve protection, IP20 finger-safe design, and DIN rail mounting for reliable electrical installation protection
The Legrand DX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This 3-pole, 50A C-curve breaker features a 10kA breaking capacity at 400V and is certified according to IEC 60898-1 standards for household installations. The device provides maximum energy limitation with class 3 current limiting capability, ensuring superior protection for your electrical system. Its IP20 finger-safe design protects against solid bodies larger than 12.5mm, making it safe for residential and commercial applications. The breaker can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. With DIN rail mounting and a built-in depth of 44mm, this compact yet powerful device integrates seamlessly into residential and small commercial panels.
The MCB DX3 features an intelligent tripping threshold for short-circuits between 250A and 500A (C curve between 5In and 10In), providing precise protection against electrical faults. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories to enhance functionality. The device is compatible with aluminium cables using terminal accessory number 4063 10, extending its applicability. Its label holder allows clear circuit identification, while the ON/OFF indication printed on the handle with red and green backgrounds ensures easy status recognition. Operating at frequencies between 50-60 Hz, the breaker maintains consistent performance across different electrical systems. The environmentally conscious design complies with substance-restriction requirements, making it an eco-friendly choice for modern electrical installations.
With rated insulation voltage of 500V and impulse withstand voltage of 4kV, this circuit breaker offers robust protection against voltage spikes and transient events. The device supports multi-wired conductors from 1.5-25mm² and solid-core conductors from 1.5-35mm², accommodating various cable sizes. Its halogen-free composition and compliance with RoHS and REACH directives demonstrate Legrand's commitment to environmental responsibility. The breaker operates reliably across ambient temperatures from -25°C to 70°C, with storage capability from -40°C to 70°C, ensuring performance in diverse climatic conditions.
