Main Documentation
Product Characteristics
| The contact system is direct-acting type with double breaking points. Aluminum alloy for the bottom base and thermal plastic sealed pack for the coil. The coil is integrated with the yoke, and they can be installed into or taken out of the contactor directly, convenient for use and maintenance. |
| Short flashover distance, within 10mm for contactor 115A…265A. Small space occupation in switchgears. |
| Maximum 4 add-on NO/NC auxiliary contacts available. |
| Three-pole and four-pole are available. |
