Shop Legrand TX3 MCB 2 Pole 63A B Curve Circuit Breaker | 403393 In Iraq Best Prices
Thermal magnetic 2-pole circuit breaker with 63A rating, B curve tripping, 6000A breaking capacity, IP20 protection, and DIN rail mounting for reliable overcurrent and short-circuit protection.
The Legrand TX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This 2-pole device features a 63A rated current and B curve tripping characteristic, providing protection between 189A and 315A for short-circuit conditions. With a breaking capacity of 6000A according to IEC 60898-1 standard, this circuit breaker is ideal for household and small commercial installations. The device offers IP20 protection against solid bodies larger than 12.5mm, ensuring fingerproof safety in residential and commercial environments.
The TX3 MCB is engineered for versatile installation options, supporting copper cable, prong busbar (top or bottom side), or fork busbar (bottom side) connections. It features a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar supplying the row remains in place. The circuit breaker incorporates maximum energy limitation with class 3 current limiting capability, minimizing let-through energy during fault conditions. With its compact 44mm built-in depth and modular design spanning 2 spacings, this device integrates seamlessly into standard distribution panels.
This product includes a convenient label holder for clear circuit identification and ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition.
