The miniaturization of the Electromagnetic Contactor has realized miniaturization across many ratings.
By standard equipping a terminal cover, the effort of specifying different model names for customers and arranging options is reduced, leading to inventory reduction and cost reduction effects from the cover. Of course, it also improves safety as protection for the charging part.
In the old series, the number of operating coil ratings was reduced from 14 types to 8 types, while expanding the applicable voltage range. This not only reduces customer inventory but also achieves shorter delivery times through the consolidation of coil manufacturing types.
It is suitable for motor overload and restraint protection.
