Shop Legrand MCB DX3 1 Pole 50A Curve D Circuit Breaker Legrand | 409812 In Iraq Best Prices
Thermal magnetic 1-pole 50A circuit-breaker with 25kA breaking capacity, D-curve tripping, IP20 finger-safe design, and 230V rated voltage for residential and commercial electrical protection.
The MCB DX3 1 Pole 50A Curve D is a thermal magnetic circuit-breaker designed to protect wiring installations against overloads and short-circuits. With a breaking capacity of 25kA at 230V, this device provides reliable protection for residential and small commercial electrical systems. The circuit-breaker features D-curve tripping characteristics, making it suitable for circuits with moderate inrush currents. It can also function as a control and isolation device for the installation, offering versatile functionality beyond basic protection.
This single-pole modular circuit-breaker is equipped with an IP20 finger-safe design, protecting against solid bodies larger than 12.5mm. The device features a red/green mechanical indicator that clearly displays the status of the contacts as either open or closed, providing visual confirmation of the circuit state. The built-in label holder allows for clear identification of circuits, making maintenance and troubleshooting easier. With a rated voltage of 230V and rated insulation voltage of 500V, it meets international safety standards including IEC 60947-2.
The MCB DX3 is compatible with Legrand DX3 auxiliaries, RCD add-on modules, and various accessories, allowing for customization based on specific installation requirements. It can be supplied by copper cable from either the top or bottom side, and with the appropriate terminal accessory, it can also be connected to aluminum cable. The device operates reliably across a frequency range of 50-60Hz and maintains performance in ambient temperatures ranging from -25°C to 70°C. Its compact design with dimensions of 26.7mm width and 79.2mm depth makes it suitable for installation in standard DIN rail enclosures.
