Shop Legrand DX3 MCB 4 Pole 1A Curve B Circuit Breaker | 409058 In Iraq Best Prices
Legrand DX3 thermal magnetic circuit-breaker providing 16kA breaking capacity at 230V and 10kA at 400V for reliable protection of wiring installations against overloads and short-circuits.
The Legrand DX3 MCB is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 16kA at 230V and 10kA at 400V, this 4-pole device offers reliable protection for residential and small commercial applications. The B curve characteristic provides tripping thresholds between 3A and 5A, making it ideal for sensitive circuits requiring precise protection. Built with IP20 protection rating and class 3 current limiting capability, this circuit-breaker ensures maximum safety and energy limitation.
This MCB features advanced installation capabilities including DIN rail mounting with independent removal functionality, allowing convenient removal without disturbing the main busbar supply. The device can be supplied by copper cable, prong busbar, fork busbar, or Legrand HX3 plug busbar configurations. With a rated current of 1A and operating voltage of 400V AC, it maintains stable performance across a frequency range of 50-60 Hz. The label holder provides clear circuit identification with ON/OFF indication printed on the handle with red and green backgrounds for easy status recognition.
The product complies with IEC 60898-1 standard for household installations and includes protection against solid bodies larger than 12.5mm. It can be equipped with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories. The halogen-free design demonstrates environmental consciousness, while the device operates reliably in ambient temperatures from -25°C to 70°C. All Legrand products must be installed by qualified electricians and maintained exclusively by Legrand-trained personnel.
