Shop Legrand TX3 MCB 3 Pole 50A 10kA Circuit Breaker | 404131 In Iraq Best Prices
Legrand TX3 3-pole thermal magnetic circuit-breaker with 50A rated current and 10kA breaking capacity for reliable protection against overloads and short-circuits in residential and commercial installations.
The Legrand TX3 MCB 404131 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This 3-pole device features a 50A rated current with a 10kA breaking capacity at 400V, making it ideal for residential and small commercial applications. The B-curve tripping characteristic ensures precise protection with tripping thresholds between 150A and 250A (3 In to 5 In), providing both control and isolation capabilities. Built with advanced current limiting technology (Class 3), this MCB delivers maximum energy limitation and superior protection performance.
This circuit-breaker is engineered with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row is still in place. The device is protected against solid bodies larger than 12.5mm with an IP20 rating according to IEC/EN 60529 standard. 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 identification. The TX3 can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options.
Complying with IEC 60898-1 standard for household installations, this Legrand product meets all substance-restriction requirements and has been designed with environmental consciousness. It supports a nominal voltage range of 240-415V with 50-60Hz frequency operation and an impulse withstand voltage of 4kV. The device can be equipped with Legrand DX3 auxiliaries and accessories for enhanced functionality, and can connect to aluminum cables using Legrand DX3 terminal accessories. With its robust construction, halogen-free materials, and comprehensive protection features, the TX3 MCB represents the ideal choice for modern electrical installations.
