Shop Legrand TX3 MCB 4P 6A Curve B Circuit Breaker 6000A | 403413 In Iraq Best Prices
Legrand TX3 4-pole 6A B-curve circuit breaker with 6000A breaking capacity. DIN rail mounted thermal magnetic protection device for household installations with IP20 fingerproof protection and current limiting class 3.
The Legrand TX3 MCB is a 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 installations. The B-curve characteristic ensures optimal tripping performance between 3In and 5In for short-circuit protection, with a tripping threshold between 18A and 30A. The device features DIN rail mounting for easy installation and removal, even when fork busbars are in place. Its compact design with 44mm built-in depth makes it ideal for space-constrained applications.
This circuit-breaker is equipped with advanced safety features including IP20 protection against solid bodies larger than 12.5mm (fingerproof protection) and current limiting class 3 according to IEC 60898-1 standard. The device can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. It features a special DIN rail clamp on the bottom side allowing independent removal without disturbing the fork busbar supplying the row. The label holder enables clear, visible identification of circuits, while on/off indication is printed on the handle with red and green backgrounds for easy status identification.
Compliant with all substance-restriction requirements and designed through an environmentally conscious process, the TX3 MCB is compatible with Legrand DX3 auxiliaries and accessories. With a rated voltage of 400V, rated insulation voltage of 500V, and impulse withstand voltage of 4kV, this device ensures maximum safety and reliability. The halogen-free construction and pollution degree 2 rating make it suitable for various installation environments. Installation should be performed by qualified electricians in compliance with local electrical codes.
