Shop Legrand TX3 MCB 1 Pole 25A Circuit Breaker B-Curve | 404086 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 25A rating, 10kA breaking capacity, and B-curve protection for residential and commercial electrical installations. IP20 rated, DIN rail mounted with advanced current limiting technology.
The Legrand TX3 MCB (Miniature Circuit Breaker) is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a robust 10kA breaking capacity, this single-pole device is rated for 25A at 230/400V AC circuits, making it ideal for residential and small commercial applications. The B-curve protection characteristic provides tripping thresholds between 75A and 125A for short-circuit conditions, ensuring reliable protection of electrical installations.
This circuit breaker features advanced current limiting technology (Class 3) that minimizes let-through energy during fault conditions, reducing equipment damage and enhancing safety. The device is equipped with a special DIN rail clamp on the bottom side, allowing independent removal even when the fork busbar is still in place. It includes a convenient label holder for circuit identification and clear ON/OFF indication printed on the handle with red and green backgrounds for easy status identification.
The TX3 MCB is built with IP20 protection rating (fingerproof against solid bodies larger than 12.5mm) and complies with IEC 60898-1 standard for household installations. It can be supplied via copper cable, prong busbar, or fork busbar connections. The device is halogen-free and designed with environmental consciousness, meeting RoHS and REACH compliance requirements. Compatible with Legrand DX3 auxiliaries and accessories for enhanced functionality.
