Shop Legrand DX3 MCB 2 Pole 4A Circuit Breaker 6000A | 407795 In Iraq Best Prices
Legrand DX3 2-pole miniature circuit breaker with 4A rated current, 6000A breaking capacity, C curve characteristic, and IP20 protection. Features dual DIN rail clamps, label holder, and compatibility with DX3 auxiliaries for reliable household and commercial installation protection.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 4A and a breaking capacity of 6000A according to IEC 60898-1 standard, this 2-pole device provides reliable protection for household and small commercial installations. The C curve characteristic offers a tripping threshold between 20A and 40A for short-circuits (5 In to 10 In), making it ideal for general purpose circuits with moderate inrush currents.
This circuit breaker is equipped with dual DIN rail clamps allowing independent removal while the prong busbar remains in place. It features a convenient label holder for circuit identification and clear ON/OFF indication with red and green backgrounds for easy status identification. The device is protected against solid bodies larger than 12.5mm (fingerproof) with IP20 rating and offers maximum energy limitation (Class 3 according to IEC 60898-1). Compatible with DX3 auxiliaries, RCD add-on modules, and various accessories, it can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar.
The MCB complies with substance-restriction requirements and has been designed with environmental consciousness. It operates reliably across a wide ambient temperature range (-25°C to 70°C) and accepts multi-wired conductors from 1.5-25mm² and solid-core conductors from 1.5-35mm². This product represents Legrand's commitment to safety, reliability, and environmental responsibility in electrical protection solutions.
