Environment according to EN 60664-1 Overvoltage category III/pollution degree 2
1
IEC 60947 parts 4 and 5. Endurance of the relay varies with different load type, switching current, ambient temperature, drive configuration, work-
ing profile, and so forth. Mount a snubber circuit when connecting inductive loads to the relays.
