Shop Legrand DX3 MCB 1 Pole 16A Curve D Circuit Breaker | 407971 In Iraq Best Prices
Single-pole thermal magnetic circuit-breaker with 16A rating, D-curve characteristic, and 6kA breaking capacity for residential electrical protection
The Legrand DX3 MCB 407971 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a rated current of 16A and D-curve characteristic, this single-pole device delivers reliable fault clearance with a breaking capacity of 6kA according to IEC 60898-1 standard for household installations. The device features a tripping threshold in case of short-circuit between 160A and 224A (D curve between 10 In and 14 In), ensuring optimal protection for residential and small commercial electrical systems.
This circuit-breaker operates at 230/400V~ with a rated insulation voltage of 500V and impulse withstand voltage of 4kV. It can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). The device is IP20 protected against solid bodies larger than 12.5mm (fingerproof) and complies with IEC/EN 60529 standard requirements.
The MCB comes equipped with two DIN rail clamps for independent removal when the busbar is still in place, a label holder for circuit identification, and clear ON/OFF indication on the handle with red and green backgrounds. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The product is halogen-free, environmentally conscious, and complies with all substance-restriction requirements, making it an ideal choice for modern electrical installations.
