Shop Legrand MCB TX3 6000A 4 Pole 20A Curve B Circuit Breaker | 403418 In Iraq Best Prices
Legrand MCB TX3 6000A 4-pole 20A B-curve thermal magnetic circuit-breaker with IP20 protection, ideal for residential and commercial installations with advanced energy limitation and DIN rail mounting.
The Legrand MCB TX3 6000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional performance. This 4-pole device provides a breaking capacity of 6000A at 400V~, making it ideal for residential and small commercial panel applications. The circuit-breaker features a B-curve release characteristic with a tripping threshold between 60A and 100A (3-5 times the rated current), ensuring optimal protection for sensitive electrical systems. With IP20 "fingerproof" safety rating according to IEC/EN 60529 standard, it prevents accidental contact with live parts. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place, and includes a label holder for clear circuit identification.
This advanced circuit-breaker meets the highest international standards including IEC 60898-1 for household installations and achieves maximum energy limitation (class 3). It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options. The MCB TX3 is compatible with Legrand DX3 auxiliaries and accessories, and can be connected to aluminum cable using Legrand DX3 terminal accessory. The device features on/off indication printed on the handle with red and green backgrounds for easy status identification.
Manufactured with environmental consciousness, this product complies with substance-restriction requirements and is halogen-free. It operates reliably across a frequency range of 50-60 Hz with a nominal voltage range of 240-415V. The compact design with dimensions of 70.8mm width, 88mm height, and 77.8mm depth (44mm built-in depth) occupies just 4 modular spacings on a DIN rail, making it space-efficient for crowded panels.
