Shop Legrand DX3 MCB 2 Pole 63A D-Curve 10kA Circuit Breaker | 409457 In Iraq Best Prices
Legrand DX3 thermal-magnetic circuit breaker with 2 poles, 63A rating, D-curve protection, and 10kA breaking capacity for residential and commercial electrical installations.
The Legrand DX3 MCB 2 Pole 63A D-Curve Circuit Breaker (Reference 409457) is a thermal-magnetic circuit breaker designed to protect residential and small commercial wiring installations against overloads and short-circuits. With a rated current of 63A and a D-curve release characteristic, this device provides reliable protection with a 10kA breaking capacity at 400V and 16kA at 230V. The circuit breaker features IP20 finger-safe protection, ensuring safety in electrical installations, and is equipped with clear ON/OFF indication for easy status identification.
This 2-pole modular circuit breaker is built for DIN rail mounting with independent removal capability thanks to dual clamps positioned on the top and bottom sides. It can be supplied through copper cables, prong busbars, fork busbars, or Legrand HX3 plug busbars, offering flexible installation options. The device complies with IEC 60898-1 standards for household installations and features a tripping threshold between 630A and 882A for short-circuit protection (D-curve between 10In and 14In).
The MCB includes a label holder for clear circuit identification and is compatible with Legrand DX3 auxiliaries and RCD add-on modules. Operating safely across ambient temperatures from -25°C to 70°C, it accepts multi-wired conductors from 1.5-25mm² and solid-core conductors from 1.5-35mm². The product is halogen-free, environmentally conscious, and built with a grey finish (RAL 7035) for professional appearance in any installation.
