Shop Legrand MCB TX3 6000A 4 Pole 63A Curve B Circuit Breaker | 403423 In Iraq Best Prices
4-pole thermal magnetic circuit-breaker with 63A rated current, 6000A breaking capacity, B-curve characteristic, IP20 protection, and energy limitation class 3 for comprehensive electrical installation protection.
The Legrand MCB TX3 6000A is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a rated current of 63A at 400V with a B-curve characteristic and an impressive 6000A breaking capacity according to IEC 60898-1 standard for household installations. The device offers IP20 finger-safe protection, ensuring safety against solid bodies larger than 12.5mm, and achieves energy limitation class 3 for maximum protection against let-through energy.
This circuit-breaker is engineered with a special DIN rail clamp on the bottom side, allowing independent removal when the fork busbar supplying the row remains in place. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side). The device includes a label holder for clear circuit identification and features ON/OFF indication printed on the handle with red and green backgrounds for easy status identification. With a built-in depth of 44mm and dimensions of 70.8mm width, 88mm height, and 77.8mm depth, it fits seamlessly into standard electrical installations.
The MCB TX3 is compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminium cable using the appropriate Legrand DX3 terminal accessory. This product complies with substance-restriction requirements and has been designed through an environmentally conscious process. It operates at frequencies between 50-60 Hz with a rated insulation voltage of 500V and an impulse withstand voltage of 4kV, making it suitable for various commercial and residential applications.
