Shop Legrand DX3 MCB 4 Pole 63A C Curve 10kA Circuit Breaker | 409342 In Iraq Best Prices
Premium 4-pole thermal magnetic circuit-breaker with 63A C curve, 10kA breaking capacity, IP20 protection, and DIN rail installation for reliable electrical circuit protection
The Legrand DX3 MCB 10000A is a premium thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. This 4-pole device features a 63A rated current with C curve release characteristic and 10kA breaking capacity at 400V, providing reliable protection for residential and small commercial applications. The MCB is IP20 protected against solid bodies larger than 12.5mm, ensuring safe control and isolation of electrical circuits. Its compact design allows installation on DIN rail with independent removal capability, while the label holder enables clear circuit identification.
This circuit-breaker complies with IEC 60898-1 standard for household installations and features current limiting class 3 for maximum energy limitation. It can be supplied via copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar, offering flexible installation options. The device is equipped with concurrently switching neutral conductor capability and supports additional Legrand DX3 auxiliaries, RCD add-on modules, and accessories for enhanced functionality. With its halogen-free construction and environmentally conscious design, this MCB represents a commitment to safety and sustainability.
The DX3 MCB operates reliably across a wide temperature range from -25°C to +70°C and supports both solid-core conductors (1.5-35mm²) and multi-wired conductors (1.5-25mm²). Its color-coded handle provides easy ON/OFF identification with red and green backgrounds respectively, while the IP20 protection degree ensures protection against accidental contact. This product is fully compliant with RoHS Directive and REACH regulations, making it an ideal choice for modern electrical installations requiring both performance and environmental responsibility.
