Shop Legrand DX3 MCB 3 Pole 25A Curve D Circuit Breaker | 409835 In Iraq Best Prices
Legrand DX3 three-pole modular circuit breaker with 25A rated current, 25kA breaking capacity at 400V, D-curve protection, and IP20 finger-safe terminals for reliable electrical circuit protection.
The Legrand DX3 MCB is a three-pole modular thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This high-performance device offers a rated breaking capacity of 25kA at 400V with a D-curve characteristic, providing reliable protection against overloads and short circuits. The circuit breaker features 25A rated current and is equipped with IP20 finger-safe terminals for enhanced safety. It can be supplied from either the top or bottom side using copper cable and is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories for comprehensive electrical system integration.
Designed with modern safety standards in mind, the DX3 MCB includes a red/green mechanical indicator that clearly displays the contact status (open or closed), along with a label holder for circuit identification. The device operates across a frequency range of 50-60 Hz and maintains performance in ambient temperatures from -25°C to 70°C. With a compact built-in depth of 47mm and a width of 80.1mm, it integrates seamlessly into standard DIN rail installations. The product complies with IEC 60947-2 standards and substance-restriction requirements, demonstrating Legrand's commitment to environmental responsibility.
This circuit breaker is engineered for professional installation and offers exceptional durability with halogen-free construction. The device provides concise circuit protection with its D-curve tripping characteristic, which activates between 250A and 350A for short-circuit conditions. It accommodates both solid-core conductors (1.5-50mm²) and multi-wired conductors (1.5-35mm²), making it versatile for various installation scenarios. The grey color (RAL 7035) and robust construction ensure long-term reliability in demanding electrical environments.
