2. High insulation resistance
Superior insulation characteristics have
been achieved by maintaining an
insulation distance between coil and
contacts of at least 10 mm for both
creepage distance and clearances.
Furthermore, anti-surge voltage is 10 kV
and higher. (Supports European
reinforced insulation requirement.)

221F for the class F.
4. Low operating power
Power saved with a nominal operating
power of only 400 mW.

This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual load.
Wave is standard shock voltage of 1.2 50s according to JEC-212-1981
In order to obtain the full rated life cycles, the relay should be properly vented by removing the vent nib. For details, please refer to NOTES.
Class F type is ambient temperature 105°C +221F.
The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to “6. Usage, Storage and Transport
Conditions” in AMBIENT ENVIRONMENT (page 626).
Please note that some of the specifications listed above may not comply with overseas standards.
