Schneider Electric
All-in-one protection for electrical systems
The 'Acti9 AFDD' protective device from Schneider Electric offers safety for buildings of all sizes by combining the protective functions of AFDD (fire circuit breaker), residual current and miniature circuit breakers and mains voltage monitoring in a single device.
By combining the diverse safety functions of RCDs, MCBs and AFDDs in a single device, the 'Acti9 AFDD' and 'Acti9 AFDD Active' circuit breakers from Schneider Electric provide reliable protection against electrical overloads, short circuits, residual currents, various fault arcs and transient mains overvoltages. They therefore guarantee personal, device and fire protection in residential and functional buildings and at the same time safely protect circuits. The protective devices also offer numerous additional functions: The integrated status display, for example, shows the tripping of the switch and the current switching position (open/closed) at all times, while the diagnostic function provides an indication of the cause of the tripping - for example due to overload, short circuit, residual current fault, serial or parallel arcing faults. Adjustable threshold values can also be set for pre-alarms in the event of overload and residual currents. The measurement function can be used to record voltage, current, residual current, active power, energy, operating hours counter and the internal device temperature. The logging function makes it possible, for example, to permanently record the number and cause of tripping or the exact date on which the test button was pressed.
Thanks to the integrated connectivity, Acti9 AFDD Active can also act as part of an active safety system in future. This will then not only act reactively, but also allow proactive intervention and continuous remote condition monitoring of the electrical system. This is because the system actively warns of potential malfunctions, electrical faults and hazards via wireless communication with the 'EcoStruxure' panel server. It sends SMS or email notifications and alarm messages in the event of anomalies such as overload, residual current or mains overvoltage, and provides meaningful diagnoses, analyses and recommendations for action.
