Shop Legrand DX3 MCB 4 Pole 6A Circuit Breaker Type B | 407621 In Iraq Best Prices
Professional-grade 4-pole thermal magnetic circuit-breaker with 6A capacity, B-curve protection, and 6kA/10kA breaking capacity for residential and small commercial electrical installations.
The Legrand DX3 MCB 6000A is a high-performance thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a rated current of 6A at 400V with a B-curve tripping characteristic and 6kA/10kA breaking capacity. The circuit-breaker can also control and isolate the installation while accepting DX3 auxiliaries for enhanced functionality. Built with advanced energy limitation technology (class 3), it provides maximum protection for residential and small commercial applications.
This device is engineered with dual DIN rail clamps for independent removal without affecting the prong busbar supply. It features fingerproof protection (IP20) against solid bodies larger than 12.5mm and complies with IEC 60898-1 standards for household installations. The MCB accepts connections from copper cables, prong busbars, fork busbars, or Legrand HX3 plug busbars, offering flexible installation options. With a B-curve tripping threshold between 18A and 30A (3In to 5In), it provides reliable protection against both gradual overloads and sudden short-circuits.
The product is halogen-free and designed with environmental consciousness, meeting RoHS and REACH compliance requirements. Its compact design with 4 modular spacings (70.8mm width) allows efficient panel mounting, while the integrated label holder enables clear circuit identification. Operating across -25°C to 70°C ambient temperatures, this circuit-breaker is suitable for diverse installation environments.
