Note: 1.
The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/−20% for AC rated current and
±15%
for DC coil resistance.
2.
Performance characteristic data are measured at a coil temperature of 23°C.
3.
The maximum voltage is one that is applicable instantaneously to the Relay coil at 23°C and not continuously.
4.
For DC-operated Relays with the LED indicator built-in, add an LED current of approx. 5 mA to the rated current.
