Shop Legrand MCB DX3 10000A 1 Pole 63A Curve B Circuit Breaker | 408878 In Iraq Best Prices
Single-pole thermal magnetic circuit breaker with 63A B-curve, 10kA/16kA breaking capacity, IP20 finger-safe design, and DIN rail mounting for reliable electrical protection.
The MCB DX3 10000A is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This single-pole modular device features a 63A B-curve characteristic with breaking capacities of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2 standard, making it ideal for household and small commercial installations. The device is IP20 finger-safe rated, protecting against solid bodies larger than 12.5mm, ensuring safe operation in various environments.
This circuit breaker offers exceptional current limiting capabilities with energy limitation class 3, minimizing let-through energy during short-circuit events. It can be supplied through copper cables, prong busbars (top or bottom), fork busbars (bottom), or Legrand HX3 plug busbars (top). The DX3 is compatible with Legrand auxiliaries, RCD add-on modules, and accessories, providing flexible system integration. With its DIN rail mounting system featuring two independent clamps, the device can be removed without affecting the busbar supply.
The product includes a convenient label holder for circuit identification and clear ON/OFF indication with red and green backgrounds for easy status identification. Operating at 230V AC with a frequency range of 50-60Hz, it handles conductor cross-sections from 1.5-25mm² (multi-wired) or 1.5-35mm² (solid-core). The device is halogen-free, environmentally conscious, and complies with all substance-restriction requirements, making it suitable for modern sustainable installations.
