The DX3 AFDD fire protection switch from Legrand is a state-of-the-art device combination that functions as both an Arc Fault Detection Device (AFDD) and a Residual Current Device (RCD) as well as a Circuit Breaker (MCB). This single-pole switch with a linked neutral conductor provides comprehensive protection against various fault conditions, including earth fault currents, overload, and short circuit. With a rated residual current of 30 mA and a surge current withstand of up to 250 A, the switch ensures reliable and safe disconnection. The clear switching position indicator and the LED status display allow for easy monitoring of operational status. The fire protection switch complies with relevant standards and is designed for mounting on a DIN rail, facilitating installation. The self-monitoring feature of the AFDD unit provides additional safety by early detection and indication of potential faults.
