Shop Legrand MCB DX3 4 Pole 80A Curve D Circuit Breaker | 409853 In Iraq Best Prices
Professional 4-pole thermal-magnetic circuit breaker with 80A rating, D-curve protection, 25kA breaking capacity, and IP20 finger-safe terminals for reliable electrical circuit protection
The MCB DX3 4 Pole 80A Curve D is a professional-grade modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced protective device features a 25kA breaking capacity at 400V AC, ensuring reliable performance in demanding electrical environments. The D-curve tripping characteristic provides optimal protection against overcurrent conditions, with a tripping threshold between 800A and 1120A, making it ideal for circuits with moderate inrush currents.
Equipped with IP20 finger-safe terminals, this circuit breaker meets international safety standards and prevents accidental contact with live components. The device features a red/green mechanical indicator that clearly displays the status of the contacts (open or closed), enabling quick visual verification of circuit status. Built-in label holders allow for convenient circuit identification, reducing maintenance time and improving electrical system organization.
The MCB DX3 is fully compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, providing flexibility for system expansion and customization. With a built-in depth of 47mm and a width of 6 modular spacings (106.8mm), it integrates seamlessly into standard DIN rail installations. The device operates reliably across a wide ambient temperature range of -25°C to +70°C and features halogen-free construction, demonstrating Legrand's commitment to environmental responsibility.
