Shop Legrand DX3 MCB 2 Pole 10A Curve D Circuit Breaker | 409819 In Iraq Best Prices
Legrand DX3 modular bipolar circuit breaker with 10A D-curve protection and 25kA breaking capacity at 400V, featuring flexible connection options and IP20 protection for residential and commercial electrical installations.
The Legrand DX3 MCB is a modular bipolar thermal-magnetic circuit breaker designed for control, protection, and isolation of electrical circuits in residential and small commercial applications. This advanced protective device delivers a 25kA breaking capacity at 400V with D-curve 10A protection, meeting international IEC 60947-2 standards. The circuit breaker features a tripping threshold for short-circuit conditions between 100A and 140A (D curve between 10 In and 14 In), ensuring reliable protection of electrical installations.
The DX3 MCB offers exceptional flexibility in installation and connection options. It can be supplied via copper cable, prong busbar (top or bottom side), fork busbar (bottom side), or Legrand HX3 plug busbar (top side), making it adaptable to various electrical configurations. The device is protected against solid bodies larger than 12.5mm with IP20 rating according to IEC/EN 60529 standards, ensuring safe operation in standard indoor environments. With its compact 44mm built-in depth and 2-module width, it fits seamlessly into standard DIN rail installations.
This product incorporates environmentally conscious design principles and complies with substance-restriction requirements including RoHS and REACH regulations. The DX3 can be equipped with Legrand auxiliaries, RCD add-on modules, and various accessories for enhanced functionality. It features convenient on/off indication printed on the handle with red and green backgrounds for easy status identification, and includes a label holder for clear circuit identification. The device operates reliably across a wide temperature range (-25°C to +70°C) and is halogen-free, making it suitable for modern electrical installations requiring environmental compliance.
