Legrand TX3 thermal magnetic circuit breaker with 2-pole, 25A, B-curve, 6000A breaking capacity for reliable protection of residential and small commercial wiring installations.
The Legrand TX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits while providing control and isolation capabilities. With a 2-pole configuration rated at 25A and B-curve release characteristic, this device delivers reliable protection for residential and small commercial applications. The TX3 features a 6000A breaking capacity according to IEC 60898-1 standard, making it suitable for household installations. The device incorporates advanced energy limitation technology (Class 3) to minimize let-through energy during fault conditions, ensuring maximum safety and equipment protection.
This circuit breaker is equipped with a special DIN rail clamp on the bottom side, allowing independent removal when the fork busbar is still in place. The device provides fingerproof protection (IP20) against solid bodies larger than 12.5mm and features a label holder for clear circuit identification. The B-curve release characteristic ensures a tripping threshold between 75A and 125A (3 In to 5 In), providing optimal protection for standard wiring installations. The TX3 can be supplied via copper cable, prong busbar, or fork busbar connections, offering flexible installation options.
Compliant with substance-restriction requirements and designed with environmental consciousness, the TX3 MCB represents Legrand's commitment to safety and sustainability. The device features on/off indication printed on the handle with red and green backgrounds for easy status identification. With a rated voltage of 400V, rated insulation voltage of 500V, and impulse withstand voltage of 4kV, this circuit breaker meets all modern electrical safety standards. The halogen-free construction and compatibility with Legrand DX3 auxiliaries and accessories make it an ideal choice for modern electrical installations.
