The mains field switch-off device ('mains disconnector') NFA 63 monitors the circuit and switches off the mains voltage as soon as the last consumer is switched off. This also switches off the electrical fields. The monitoring voltage is only 2.5V DC. The use of such devices is particularly recommended for bedroom circuits (quiet zones). The NFA 63 is simply connected downstream of the circuit breaker (max. 16A) of the corresponding circuit., The NFA 63 can also be switched on by external control via its additional control input (B1). This means that a fixed voltage supply can be guaranteed at certain times of the day, for example with the help of a timer., TVE/TVA - 0.1/8s, monitoring voltage 2.5V DC, operating voltage 230V AC, 1 normally open contact 16A, dimensions: 18x55mm
