Shop Legrand DX3 MCB 4 Pole 16A Circuit Breaker D-Curve | 409533 In Iraq Best Prices

Advanced 4-pole thermal magnetic circuit breaker with 16A D-curve and 10000A breaking capacity, designed for reliable protection of residential and commercial wiring installations with DX³ auxiliary compatibility.

The Legrand DX3 MCB 10000A 4 Pole 16A Curve D is a thermal magnetic circuit-breaker specifically designed to protect wiring installations against overloads and short-circuits. With its 16A D-curve release characteristic and impressive 10000A breaking capacity at 400V~, this device delivers reliable and consistent protection for residential and small commercial applications. The 4-pole design ensures comprehensive circuit protection across all phases, while its compatibility with DX³ auxiliaries provides flexible control and monitoring options. This circuit breaker features advanced safety specifications including a rated impulse withstand voltage of 4 kV and dual breaking capacities (16 kA at 230V and 10 kA at 400V according to IEC 60947-2 standards). The device is protected against solid bodies larger than 12.5mm with IP20 rating, ensuring safe operation in standard environments. Its modular design allows installation on standard DIN rails with independent removal capability, making maintenance and replacement straightforward even when the busbar system remains energized. The MCB incorporates practical features such as a label holder for clear circuit identification and intuitive on/off indication with color-coded handles (red for off, green for on). The device supports multiple connection methods including copper cables, prong busbars, fork busbars, and Legrand HX3 plug busbars. With halogen-free construction and environmentally conscious design, this circuit breaker meets modern sustainability requirements while delivering superior electrical protection.
