Shop Legrand TX3 MCB 3P 25A Curve B 6000A Circuit Breaker | 403404 In Iraq Best Prices
Thermal magnetic circuit-breaker with 3P, 25A, 400V~ B curve and 6000A breaking capacity. Features IP20 finger-safe protection, DIN-rail mounting, and advanced energy limitation technology for reliable overload and short-circuit protection.
The Legrand TX3 MCB 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a 3-pole configuration, 25A rated current, 400V~ supply, and B curve characteristic, this device provides reliable protection for residential and small commercial electrical systems. The circuit breaker features a 6000A breaking capacity according to IEC 60898-1 standard, ensuring maximum safety and performance in household installations. It offers IP20 finger-safe protection, preventing accidental contact with live parts, and is equipped with DIN-rail mounting for easy and secure installation.
This MCB incorporates advanced current limiting technology (Class 3 energy limitation) that minimizes let-through energy during fault conditions, protecting downstream equipment from damage. The device can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. It features a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place. The product is fitted with a convenient label holder for clear circuit identification and includes On/Off indication printed on the handle with red and green backgrounds for easy status recognition.
The TX3 MCB is fully compliant with environmentally conscious design principles and substance-restriction requirements. It can be equipped with Legrand DX3 auxiliaries and accessories, and supports connection to aluminum cable using Legrand DX3 terminal accessories. With its comprehensive protection features, reliable performance, and user-friendly design, this circuit breaker is an essential component for modern electrical installations requiring robust overload and short-circuit protection.
