Product Description
These non-reversing IEC contactors connect and disconnect power to motors and other high-current equipment and machinery in a single direction. Contactors combine with overload relays to create motor load starters and provide overload protection. They can operate without overload relays but won’t have protection from overcurrent. Compatible auxiliaries can be added to increase the functionality of contactors.
