Shop Legrand DX3 MCB 1P+N 16A Curve B Circuit Breaker | 407475 In Iraq Best Prices
Legrand DX3 thermal-magnetic MCB with 6000A breaking capacity, 16A B-curve rating, IP20 protection, and DIN rail mounting for residential and small commercial electrical installations.
The Legrand DX3 MCB 6000A is a thermal-magnetic circuit breaker designed to protect wiring installations against overloads and short circuits. With a breaking capacity of 6000A at 230V AC, this single-pole plus neutral device features a B-curve 16A tripping characteristic and IP20 finger-safe protection. The breaker incorporates DIN rail mounting with dual clamps for independent removal, making it ideal for residential and small commercial panel installations. Its current-limiting class 3 design ensures maximum energy limitation according to IEC 60898-1 standards, providing superior protection for modern electrical systems.
This MCB is equipped with advanced safety features including a label holder for clear circuit identification and color-coded ON/OFF indication on the handle (red for OFF, green for ON). The device supports connection via copper cable or prong busbar from either the top or bottom, offering flexible installation options. With a rated voltage of 230V and impulse withstand voltage of 4kV, it meets all international standards for household and small commercial applications. The halogen-free construction demonstrates Legrand's commitment to environmental responsibility.
The DX3 series is compatible with Legrand DX3 auxiliaries and accessories, allowing for system expansion and customization. Operating efficiently across a frequency range of 50-60Hz with ambient temperatures from -25°C to 70°C, this circuit breaker delivers reliable performance in diverse climatic conditions. Its compact design with a width of only 17.8mm and depth of 77.6mm makes it space-efficient for crowded panel installations.
