Shop Legrand DX3 MCB 3 Pole 16A B-Curve Circuit Breaker | 408991 In Iraq Best Prices

3-pole thermal-magnetic circuit breaker with 16A B-curve rating, 10000A breaking capacity, and IP20 fingerproof protection for residential and commercial installations

The Legrand DX3 MCB is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a rated current of 16A and B-curve release characteristic, this 3-pole breaker provides a breaking capacity of 10000A at 400V~. It serves dual functions as both a protective device and a control/isolation switch for electrical installations. The device is IP20 rated for fingerproof protection and can accept DX3 auxiliaries and RCD add-on modules for enhanced functionality. This circuit breaker features advanced energy limitation (class 3 according to IEC 60898-1 standard) and is equipped with dual DIN rail clamps for independent removal without affecting the prong busbar supply. The breaker includes a convenient label holder for circuit identification and clear ON/OFF indication on the handle with red and green backgrounds. It accommodates both copper and aluminum cables with appropriate terminal accessories and maintains optimal performance across 50-60 Hz frequencies. The product complies with all substance-restriction requirements and has been manufactured through an environmentally conscious process. With a built-in depth of 44mm and width of 53.1mm, it fits standard DIN rail installations. The breaker is suitable for residential and small commercial applications, offering reliable protection with a rated insulation voltage of 500V and impulse withstand voltage of 4kV.
