Application

This contactor is specifically designed for switching capacitive loads using a unique two-stage switching method enabled by auxiliary contacts. This design prevents the wear and welding of main contacts commonly found in conventional contactors, thereby enhancing longevity and reliability. Unlike traditional contactors, this model effectively dampens transient phenomena, which can cause interference with communication networks (e.g., telecommunications and computer networks).

Construction and Benefits

The KG3-32A00 24 contactor features auxiliary pre-contacts mounted on the body, which engage a few milliseconds before the main contacts. This allows the current surge to be reduced by up to 70 times the nominal current (Ie) through the use of series resistors. This advanced design makes the contactor highly suitable for applications with high switching frequency, ensuring a long lifespan and maintaining the reliability of compensation devices.

The KG3-32A00 24 contactor is available with optional auxiliary contacts (normally open or closed), making it compatible with remote communication systems. It can be mounted on a DIN rail or secured with screws for added versatility.

Conclusion

This contactor is an ideal choice for applications that demand high switching power, up to 100 kVAr, combined with durability and superior performance. Thanks to its innovative design, the KG3-32A00 24 offers extended operational life, reduced maintenance needs, and improved overall system reliability.
