Shop Legrand MCB TX3 6000A 1 Pole 50A Curve B Circuit Breaker | 403362 In Iraq Best Prices
Single-pole thermal magnetic circuit-breaker with 6000A breaking capacity, B curve characteristic, and IP20 protection for household electrical installations. Features DIN rail mounting, label holder, and compatibility with Legrand DX3 accessories.
The Legrand MCB TX3 is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional performance. This single-pole device features a 6000A breaking capacity according to IEC 60898-1 standard, making it ideal for household and small commercial applications. The B curve characteristic provides a tripping threshold between 150A and 250A (3 In to 5 In), ensuring precise protection for standard household circuits while preventing nuisance trips during normal operation.
This circuit-breaker offers versatile installation options, accommodating copper cables, prong busbars (top or bottom side), or fork busbars (bottom side). With an IP20 protection rating, it is protected against solid bodies larger than 12.5mm, meeting fingerproof safety standards. The device features energy limitation class 3 according to IEC 60898-1, providing maximum let-through energy limitation for enhanced safety. The built-in DIN rail clamp allows independent removal even when the fork busbar supplying the row remains in place.
Designed with user convenience in mind, this MCB includes a label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds. The device complies with all substance-restriction requirements and has been designed in an environmentally conscious process. It can be equipped with Legrand DX3 auxiliaries and accessories, and can be connected to aluminum cable using Legrand DX3 terminal accessories, making it a versatile solution for modern electrical installations.
