Shop Legrand TX3 MCB 1 Pole 40A C Curve 6kA Circuit Breaker | 403438 In Iraq Best Prices
Legrand TX3 single-pole 40A MCB with 6kA breaking capacity, C curve release, IP20 protection, and flexible connection options for reliable electrical circuit protection in residential installations.
The Legrand TX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With a rated current of 40A and a 6kA breaking capacity according to IEC 60898-1 standard, this single-pole device features a C curve release characteristic with tripping thresholds between 200A and 400A (5 In to 10 In). The MCB provides IP20 "fingerproof" protection, preventing contact with solid bodies larger than 12.5mm, ensuring safe operation in household and residential installations.
This circuit breaker can be supplied through multiple connection options including flexible copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering maximum flexibility for installation requirements. The device features energy limitation class 3 according to IEC 60898-1 standard, providing superior protection against short-circuit damage. The TX3 series is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place.
The Legrand TX3 MCB is compatible with DX3 auxiliaries and accessories, making it highly adaptable for various electrical system configurations. It can be connected to aluminium cable using Legrand DX3 terminal accessory, and features a label holder for clear circuit identification. The device complies with substance-restriction requirements and has been designed following environmentally conscious manufacturing processes. Operating at 230V rated voltage with 50-60Hz frequency, this MCB is an essential component for reliable electrical protection in modern installations.
