Shop Legrand MCB TX3 10000A 3 Pole 25A Curve B Circuit Breaker | 404128 In Iraq Best Prices

Advanced 3-pole thermal magnetic circuit breaker with 10kA breaking capacity, B-curve tripping, and IP20 protection for reliable electrical installation safeguarding

The Legrand MCB TX3 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 10kA at 400V, this 3-pole device features a B-curve tripping characteristic with a threshold between 75A and 125A (3-5 times the rated current). The MCB can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), making it versatile for various installation configurations. This circuit breaker is equipped with advanced safety features including IP20 protection against solid bodies larger than 12.5mm (fingerproof), maximum energy limitation class 3 according to IEC 60898-1 standard, and compatibility with Legrand DX3 auxiliaries and accessories. The device can also be connected to aluminium cable using Legrand DX3 terminal accessory. With a rated current of 25A and rated voltage of 400V, it provides reliable protection for residential and small commercial applications. The MCB TX3 features a special DIN rail clamp on the bottom side allowing independent removal even when the fork busbar is still in place. It includes a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds. The device complies with substance-restriction requirements and has been designed following environmentally conscious processes, making it an eco-friendly choice for modern electrical installations.
