Thermal magnetic circuit-breaker with 10kA breaking capacity, 4-pole 63A protection, C curve characteristic, IP20 rating, and advanced energy limitation for comprehensive electrical installation protection.
The Legrand TX3 MCB TX3 10000A 4 pole 63A curve C is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional performance and reliability. This advanced protective device features a breaking capacity of 10kA at 400V and incorporates a C curve characteristic for optimal protection of standard electrical installations. The device controls and isolates the installation effectively, offering comprehensive 4-pole, 63A protection with IP20 rating for fingerproof protection against solid bodies larger than 12.5mm.
Engineered to the highest international standards including IEC 60898-1, this circuit breaker delivers superior energy limitation (class 3) and precise tripping thresholds between 315A and 630A for short-circuit protection. The MCB can be supplied via copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), providing flexible installation options. Its special DIN rail clamp with bottom-side mounting allows independent removal even when the fork busbar supplying the row remains in place, ensuring maintenance convenience and safety.
The TX3 circuit breaker is environmentally conscious, halogen-free, and complies with all substance-restriction requirements. It features 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. Compatible with Legrand DX3 auxiliaries and accessories, this device represents the pinnacle of electrical protection technology for residential and small commercial applications.
