Shop Legrand MCB TX3 6000A 4 Pole 50A Curve B Circuit Breaker | 403422 In Iraq Best Prices
Legrand MCB TX3 4-pole 50A circuit breaker with 6000A breaking capacity, B curve protection, IP20 rating, and advanced current limiting for reliable household and commercial electrical distribution.
The Legrand MCB TX3 6000A is a high-performance thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a breaking capacity of 6000A at 400V~, this 4-pole device delivers reliable protection for household and small commercial electrical distributions. The B curve tripping characteristic ensures rapid disconnection when short-circuit currents between 150A and 250A (3 to 5 times the rated current) are detected, providing superior safety for your electrical infrastructure.
This circuit breaker features IP20 protection rating, making it fingerproof against solid bodies larger than 12.5mm, ensuring safe operation in residential and commercial environments. The device incorporates advanced current limiting technology (Class 3 energy limitation) to minimize let-through energy during fault conditions. With its compact 44mm built-in depth and modular design, the TX3 can be easily integrated into DIN rail installations. The special DIN rail clamp allows independent removal even when fork busbars remain in place, facilitating maintenance and troubleshooting.
The MCB TX3 is compatible with Legrand DX3 auxiliaries and accessories, providing flexibility for system expansion and customization. It supports multiple connection methods including copper cables, prong busbars, and fork busbars. The device is halogen-free and manufactured following environmentally conscious processes, complying with substance-restriction requirements. A convenient label holder enables clear circuit identification, while the color-coded handle (red for OFF, green for ON) provides immediate status indication.
