Shop Legrand MCB TX3 6000A 3 Pole 20A Circuit Breaker C Curve | 403546 In Iraq Best Prices
Professional 3-pole thermal magnetic circuit-breaker with 20A rated current, 6000A breaking capacity at 400V, C curve tripping, and advanced energy limitation for reliable electrical protection in residential and commercial installations.
The Legrand MCB TX3 6000A is a premium thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits with exceptional reliability. This 3-pole device features a 20A rated current with C curve tripping characteristics, providing optimal protection for residential and small commercial applications. With a breaking capacity of 6000A at 400V, it ensures superior fault protection while maintaining compatibility with standard DIN rail installations.
This circuit-breaker incorporates advanced energy limitation technology (Class 3 according to IEC 60898-1 standard) that minimizes let-through energy during fault conditions. The device features a special DIN rail clamp allowing independent removal even when the fork busbar is still in place, ensuring safe maintenance and installation flexibility. It can be supplied by copper cable, prong busbar (top or bottom side), or fork busbar (bottom side), making it highly adaptable to various installation configurations.
The MCB TX3 is engineered with fingerproof protection (IP20 rating) against solid bodies larger than 12.5mm, ensuring safety in residential environments. It includes a convenient label holder for clear circuit identification and on/off indication printed on the handle with red and green backgrounds. Compliant with all substance-restriction requirements and designed with environmental consciousness, this circuit-breaker is compatible with Legrand DX3 auxiliaries and accessories, providing a complete solution for modern electrical installations.
