Shop Legrand MCB TX3 6000A 2 Pole 50A Curve C Circuit Breaker | 403533 In Iraq Best Prices
Professional 2-pole 50A circuit breaker with 6000A breaking capacity, C curve characteristic, and advanced protection for residential and commercial electrical installations.
The Legrand MCB TX3 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits while providing control and isolation capabilities. This 2-pole device features a 50A rated current with C curve characteristic and 230/400V~ rating, delivering a breaking capacity of 6000A according to IEC 60898-1 standard for household installations. The MCB is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place, making installation and maintenance significantly more convenient.
This circuit breaker incorporates advanced protection features including a tripping threshold for short-circuit protection between 250A and 500A (C curve between 5 In and 10 In), and offers maximum energy limitation with class 3 current limiting capability. The device is fingerproof (IP20 according to IEC/EN 60529) and can be supplied by copper cable, prong busbar, or fork busbar configurations. With its grey RAL 7035 color finish and compact 35.4mm width occupying 2 modular spacings, it integrates seamlessly into standard DIN rail installations.
The TX3 MCB is compatible with Legrand DX3 auxiliaries and accessories, and supports aluminum cable connections using Legrand DX3 terminal accessories. It features a convenient label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds for easy status recognition. The device complies with substance-restriction requirements and has been designed following environmentally conscious processes, making it an ideal choice for modern electrical installations requiring reliable protection and control.
