Overview
The VAF3-40M is a magnetic arc fault detection device combining arc-fault detection with Type A residual-current, overload and short-circuit protection. Designed for AC 50 Hz final circuits, it has a rated voltage of 240 V AC and is available in rated currents from 6 A to 40 A. The 1P+N device offers B or C overcurrent tripping characteristics and 10 mA or 30 mA residual-current sensitivities. It is intended for residential and commercial final circuits requiring combined protection against arc faults, electric shock, overload and short circuits.
