Load limit curve for 788-404, 788-607 and 788-608
* In order to prevent the gold layer from being damaged
these values should not be exceeded. Higher
switching power leads to evaporation of the gold layer.
The resulting deposits in the enclosure may
cause sparkovers between the coil and the contact.
