The 7-1618413-0 is a KILOVAC K1K series high-voltage contactor engineered for high-current applications in harsh environments. It features a maximum voltage rating of 1000 VDC and a continuous current rating of 1000 A, with an SPST-NO contact arrangement. The device operates with a nominal 24 VDC coil that includes an integrated dual-coil electronic economizer for efficiency. Its hermetically sealed design prevents contact oxidation and allows for use in explosive atmospheres over an operating temperature range of -40°C to +105°C. This contactor is ideal for applications such as main disconnects for battery storage, power distribution, and alternative energy systems where reliable, high-power switching is critical.
