Shop Legrand DX3 MCB 4 Pole 100A Circuit Breaker C-Curve | 409363 In Iraq Best Prices
Professional 4-pole 100A C-curve circuit breaker with 10kA/16kA breaking capacity, IP20 finger-safe terminals, and advanced thermal-magnetic protection for reliable electrical circuit management.
The Legrand DX3 MCB (Miniature Circuit Breaker) is a professional-grade 4-pole modular thermal-magnetic circuit breaker designed for comprehensive control, protection, and isolation of electrical circuits in residential and small commercial applications. This robust device delivers 100A rated current protection with a C-curve release characteristic, offering 10kA breaking capacity according to IEC 60898-1 standard and 16kA according to IEC 60947-2 standard at 400V AC. The circuit breaker features IP20 finger-safe terminals that protect against solid bodies larger than 12.5mm, ensuring safe installation and operation in various environments.
Equipped with advanced safety features, the DX3 MCB incorporates a red/green mechanical indicator that clearly displays the contact status (open or closed), and includes a convenient label holder for easy circuit identification. The thermal-magnetic tripping mechanism activates between 500A and 1000A (5-10 times the rated current), providing reliable short-circuit protection. The device supports both top and bottom copper cable supply connections and can be installed on standard DIN rails with a 6-module spacing width. It is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, offering flexible system integration.
Designed with environmental consciousness, this circuit breaker complies with substance-restriction requirements and is halogen-free. Operating across a wide temperature range from -25°C to +70°C, the DX3 MCB maintains consistent performance in diverse climatic conditions. The 47mm built-in depth and compact 70.8mm width make it ideal for space-constrained installation environments. With a rated insulation voltage of 500V and impulse withstand voltage of 4kV, this professional-grade device meets all modern electrical safety standards and regulations.
