Shop Legrand DX3 MCB 4 Pole 25A Circuit Breaker B-Curve 6kA | 407626 In Iraq Best Prices
Thermal magnetic 4-pole circuit breaker with 25A rating, B-curve characteristic, and 6kA breaking capacity. Features IP20 fingerproof protection, DIN rail mounting, and compatibility with Legrand DX3 accessories.
The Legrand DX3 MCB 407626 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device operates at 25A with a 400V~ B-curve characteristic and provides 6kA/10kA breaking capacity according to IEC 60898-1 standard for household installations. The circuit breaker features IP20 fingerproof design, protecting against solid bodies larger than 12.5mm, making it safe for general installations.
This modular circuit breaker can be supplied by copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side). It is equipped with two DIN rail clamps for independent removal while the prong busbar remains in place. The device offers maximum energy limitation (class 3) and can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality.
The DX3 MCB incorporates environmentally conscious design principles and complies with substance-restriction requirements. It features a label holder for circuit identification, with ON/OFF indication printed on the handle using red and green backgrounds for easy status identification. The device operates reliably across a frequency range of 50-60 Hz and maintains performance in ambient temperatures from -25°C to +70°C.
