“Heavy duty” air contactors (type ES series), due to their design and high reliability of operation, are particularly suitable for use in primary, metallurgical and chemical industries, conveyor systems and shipbuilding, as well as in mechanical engineering.
They are used for direct switching of all types of motors, star-delta combinations and reverse switching, for switching capacitors, brake fans, etc. used. Together with separately mounted thermal overcurrent triggers, they can also be used as motor circuit breakers.
Special Features (ES)
Long mechanical life
Highest possible operational safety in the harshest operating conditions
High switching cycles
Can be used in three-phase 66o V systems
Minimum maintenance and supervision
No mechanical wear parts
Easy and quick replacement of electrical wear parts
