Shop Legrand MCB TX3 6000A 3 Pole 63A Curve B Circuit Breaker | 403408 In Iraq Best Prices
Three-pole thermal magnetic circuit breaker with 6000A breaking capacity, B-curve protection, and IP20 safety rating for residential and commercial electrical installations.
The Legrand MCB TX3 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability and precision. This three-pole device features a 6000A breaking capacity at 400V~, making it ideal for residential and small commercial panel applications. The B-curve tripping characteristic provides precise protection between 3 and 5 times the rated current, ensuring optimal safety for your electrical system. With its IP20 "fingerproof" safety rating, this circuit breaker meets IEC/EN 60529 standards and protects against solid bodies larger than 12.5mm.
The MCB TX3 6000A offers advanced energy limitation with Class 3 current limiting capability according to IEC 60898-1 standard, minimizing let-through energy during fault conditions. It can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is in place. The built-in label holder enables clear circuit identification, while ON/OFF indication printed on the handle with red and green backgrounds ensures easy status recognition.
This product complies with substance-restriction requirements and has been designed with environmental consciousness in mind. It can be equipped with Legrand DX3 auxiliaries and accessories for extended functionality, and supports connection to aluminum cable with Legrand DX3 terminal accessory. The MCB TX3 represents Legrand's commitment to quality, safety, and reliability in electrical protection, suitable for professional installation in compliance with local electrical codes.
