Shop Legrand DX3 4P 10A Curve C Circuit Breaker 25kA | 409793 In Iraq Best Prices
Professional 4-pole circuit breaker with 25kA breaking capacity, C curve protection, IP20 terminals, and flexible busbar/cable connections for reliable electrical circuit protection
The Legrand DX3 is a four-pole modular thermal-magnetic circuit breaker designed for reliable control, protection, and isolation of electrical circuits in residential and small commercial installations. This advanced protection device delivers exceptional performance with a 25kA breaking capacity at 400V~, featuring C curve tripping characteristics that provide optimal protection against short circuits with tripping thresholds between 50A and 100A (5-10 times the rated current). The MCB is engineered with IP20 finger-safe terminals, ensuring safe operation in standard environments while preventing accidental contact with live components.
This circuit breaker offers flexible installation options, accepting power supply from copper cables, prong busbars (top or bottom side), fork busbars (bottom side), or Legrand HX3 plug busbars (top side). The device features dual DIN rail clamps positioned on both top and bottom sides, allowing independent removal even when the busbar supply remains in place. With its compact 44mm built-in depth and 4-module width, it integrates seamlessly into modern electrical panels. The unit 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 recognition.
Designed with environmental consciousness and compliance with substance-restriction requirements, the DX3 MCB operates reliably across a wide ambient temperature range of -25°C to +70°C. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. The device maintains a rated insulation voltage of 500V and impulse withstand voltage of 4kV, with pollution degree 3 rating suitable for standard indoor installations. This professional-grade circuit breaker is ideal for protecting circuits rated up to 10A in 230V or 400V AC systems at 50-60Hz frequency.
