NOTES

Avoid using in the location where there is organic gas such as SO₂ gas and H₂S gas. Note that switching contact in the silicon atmosphere may result in contact failure.
The switching voltage and current to the contact should not exceed the rated value.
The rated contact capacity and life are typical values. Since contact conditions and life vary depending on kinds of loads and other conditions, please examine them through actual conditions.
Relays should be used within the rated ambient temperature.
