Shop Legrand DX3 MCB 4 Pole 125A Circuit Breaker D-Curve | 409542 In Iraq Best Prices
Legrand DX3 four-pole 125A D-curve circuit breaker with 10kA/16kA breaking capacity, IP20 finger-safe terminals, and DIN rail mounting for reliable electrical circuit protection.
The Legrand DX³ MCB is a four-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 delivers 125A rated current protection at 400V with exceptional breaking capacity of 10kA according to IEC 60898-1 standard and 16kA according to IEC 60947-2 standard. The D-curve release characteristic provides reliable protection with a tripping threshold between 1250A and 1750A (10 to 14 times the rated current), making it ideal for circuits with moderate inrush currents.
The circuit breaker features IP20 finger-safe terminals with screwed connections, protecting against solid bodies larger than 12.5mm and ensuring safe operation in various environments. Built with halogen-free materials and designed with environmental consciousness, this device complies with substance-restriction requirements and RoHS directives. The compact 47mm built-in depth allows for space-efficient installation on DIN rails, while the red/green mechanical indicator clearly displays the open or closed status of contacts. The label holder enables clear identification of circuits for convenient maintenance and troubleshooting.
This product is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, offering flexible configuration options for complex electrical installations. The device operates across 50-60Hz frequencies and maintains performance in ambient temperatures ranging from -25°C to 70°C. It supports both top and bottom electrical supply connections and accommodates multi-wired conductors from 6-50mm² and solid-core conductors from 6-70mm², providing versatile installation capabilities.
