Shop Legrand TX3 MCB 2P 63A 10kA Curve B Circuit Breaker | 404118 In Iraq Best Prices
Professional 2-pole miniature circuit breaker with 63A rated current, 10kA breaking capacity, and B-curve protection for residential and commercial electrical installations.
The Legrand TX3 MCB (Miniature Circuit Breaker) is a professional-grade thermal magnetic circuit-breaker designed to protect and control wiring installations against overloads and short-circuits. This 2-pole device delivers exceptional 10kA breaking capacity at 230V and 10kA at 400V, making it suitable for both residential and small commercial applications. With a B-curve tripping characteristic and rated current of 63A, it provides reliable protection for 230/400V AC circuits with frequencies between 50-60 Hz. The device features current limiting class 3 according to IEC 60898-1 standard, ensuring maximum limitation of let-through energy during fault conditions. Built with a special DIN rail clamp on the bottom side, it allows independent removal even when the fork busbar is still in place, making maintenance and replacement straightforward.
This circuit breaker incorporates advanced safety features including IP20 protection against solid bodies larger than 12.5mm (fingerproof), complying with IEC/EN 60529 standards. The unit is equipped 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. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options. The TX3 is fully compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cable using Legrand DX3 terminal accessory. With a rated insulation voltage of 500V and impulse withstand voltage of 4kV, this device meets the highest safety standards for electrical installations.
The product is manufactured with environmental consciousness, complying with substance-restriction requirements and halogen-free specifications. Its compact dimensions (35.4mm width, 88mm height, 77.8mm depth) and grey colour (RAL 7035) make it suitable for modern electrical cabinets. The device operates reliably across storage temperatures from -40°C to +70°C and nominal voltages between 240-415V. With screwed terminal connections and busbar compatibility, the TX3 MCB represents the ideal solution for reliable circuit protection in residential and small commercial electrical installations.
