AC Current
Nominal current (In): 1 and 5 A dual rated.
(1A and 5A inputs use different transformer tap
connections, check correct terminals are
wired).
Nominal burden:
<0.04 VA at In, <40m(0-30In)In = 1A
<0.01 VA at In, <8m(0-30In) In = 5A
Thermal withstand:
continuous 4 In
for 10 s: 30 In
for 1 s; 100 In
Standard: linear to 64 In (non-offset AC
current).
Sensitive: linear to 2 In (non-offset AC
current).
AC Voltage
Nominal voltage (Vn): 100 to 120 V or 380 to
480 V phase-phase.
Nominal burden per phase: < 0.02 VA at
110/3 V or 440/3 V
Thermal withstand:
continuous 2 Vn
for 10s: 2.6 Vn
Linear to 200V (100V/120V), 800V (380/480V).
Power Supply
Auxiliary Voltage (Vx)
Three ordering options:
(i) Vx: 24 to 48 Vdc
(ii) Vx: 48 to 110 Vdc, and 30 to 100Vac (rms)
(iii) Vx: 110 to 250 Vdc, and 100 to
240Vac (rms)
Operating Range
(i) 19 to 65V (dc only for this variant)
(ii) 37 to 150V (dc), 24 to 110V (ac)
(iii) 87 to 300V (dc), 80 to 265V (ac).
With a tolerable ac ripple of up to 12% for a dc
supply, per IEC 60255-11: 1979.
Nominal Burden
Quiescent burden: 11W or 24 VA. (Extra
1.25W when fitted with second rear
communications board).
Additions for energized binary inputs/outputs:
Per opto input:
0.09W (24 to 54V),
0.12W (110/125V),
0.19W (220/250V).
Per energized output relay: 0.13W
Power-up Time
Time to power up < 11s.
Power Supply Interruption
Per IEC 60255-11: 1979:
The relay will withstand a 20ms interruption
in the DC auxiliary supply, without
de-energizing.
Per IEC 61000-4-11: 1994:
The relay will withstand a 20ms interruption
in an AC auxiliary supply, without
de-energizing.
