Shop Legrand MCB TX3 10000A 1 Pole 16A Curve B Circuit Breaker | 404084 In Iraq Best Prices
Thermal-magnetic circuit breaker with 10000A breaking capacity, B-curve characteristic, 16A rated current, and IP20 protection for household electrical installations. Features DIN rail mounting, multiple connection options, and energy limitation class 3.
The MCB TX3 is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits with a breaking capacity of 10000A, specifically engineered for household installations. This device serves dual purposes as both a protective element and a control and isolation switch for electrical installations. With IP20 protection rating, it safeguards against solid bodies larger than 12.5mm, making it suitable for fingerproof applications. The circuit breaker features a B-curve tripping characteristic with a short-circuit tripping threshold between 48A and 80A (3 In to 5 In), providing reliable protection for residential electrical systems.
The TX3 circuit breaker can be supplied through multiple connection methods including copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), offering flexible installation options for various electrical configurations. It features maximum energy limitation with energy limitation class 3 according to IEC 60898-1 standard, ensuring superior protection performance. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal when the fork busbar is still in place. Additionally, it includes a label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds for easy status identification.
Designed with environmental consciousness, this Legrand product complies with substance-restriction requirements and can be equipped with Legrand DX3 auxiliaries and accessories for enhanced functionality. The device is compatible with aluminium cables when using Legrand DX3 terminal accessory, providing versatile installation capabilities.
