Accuracy:
10 mHz at 50 Hz
12 mHz at 60 Hz
Accuracy: 2º
CT Ratio: 1.0 to 6000.0 in steps of 0.1
Rated currents: Appropriate for 1 or 5 A. F650 has universal range for CT (valid for 1 or 5 A to
only one terminal).
Relay Burden: < 0.04 Ohm
Current Withstand Continuous at 20 A
1 second at 500 A for phases and ground
1 second at 50 A for sensitive ground
VT Ratio 1.0 to 6000.0 in steps of 0.1
Rated Voltages 275 Vac
Metering range: From 2 to 275 Vac
Relay Burden: 0.05 VA at 120 Vac (50 or 60 Hz)
Voltage Withstand: Continuous at 260 V to neutral
1 min/hr at 420 to neutral
VAC inputs do not need varistors, as the impulse test is applied to 100% of the transformers
Input Activation Voltage Threshold: 1 to 255 Vdc in steps of 1 V (selectable by setting)
Impedance: > 100 kOhm
Maximum error:
10% setting  2.5 V
Load for voltage supervision inputs: 2 mA + V/100 kOhm
Voltage threshold for voltage supervi-
sion inputs
< 10 V (fixed)
Debounce Time: 1 to 50 in steps of 1 ms
Recognition time: < 1ms
Timing resolution: 1 ms
For Input Activation Voltage Threshold and Debounce Time there is a single setting for all inputs in the same
group (inputs sharing the same common). In mixed and supervision boards there are two groups of inputs,
called A and B.
Input Type and Delay Input Time are not grouped; there is a different setting for each input.
