Features |
| • Finger-safe terminals |
| • Auxiliary switch block snapped onto the capacitor contactor |
| • Contains three leading NO contacts and two/ three auxiliary contacts |
| • Designed to snap onto DIN rail or mount directly to a panel with screws |

Application |
• CJX4-kd Capacitor Switching Contactors are used to switch power capacitors which are
used for reactive current compensation. |
• Special series resistors and auxiliary contacts, integrated in the capacitor contactor, reduce
the high inrush current of the capacitor which would otherwise flow. This reduced inrush
current guarantees a high contactor and capacitor life time. |
