Reference Data The data shown below is based on actual measurements of samples taken
from the production line. There is some degree of variation in relay character-
istics and so this data should be used only for reference purposes.

Note 1. With a current of between 2 and 3 A (common: 8 to 10 A), either ensure
that the number of points per common that simultaneously turn ON does
not exceed 4 or ensure that the temperature does not exceed 45 ° C. There
are no restrictions if the current does not exceed 2 A (common: 8 A).
2. Using at the rated current value assures normal Unit operation but does
not assure the life expectancy of the relay itself. The relay's life expectancy
varies greatly with the operating temperature, type of load, and switching
conditions, and so be sure to check the relay characteristics under the ac-
tual operating conditions.
