Ratings
Coil
Note 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of+15%/-20% (AC rated current) or ±10% (DC coil resistance).
2.AC coil resistances shown above are only reference values.
3.The operating characteristics are measured at a coil temperature of 23°C.
4.The “Max. voltage” is the maximum voltage that can be applied to the relay coil.

Measurement: after the relay kept static by
applying a rated voltage, leave the relay at room

of 80°C ± 2°C respectively, to measure how the
keep-power varies with time.
