02/26/2026 Product News

With the new KW21A series, Rutronik expands JAE’s automotive portfolio, complementing the MX81 series with another key component for the growing charging infrastructure market. The CCS2-compatible DC charging connectors KW21A are specifically designed to meet the increasing demand for fast-charging solutions for electric vehicles. They support rated charging currents of 40 A or 100 A at system voltages up to 1,000 VDC and enable bidirectional Vehicle-to-Grid (V2G) charging. A robust plastic housing with double insulation ensures high weather resistance and maximum safety. They are now available at www.rutronik24.com.

The connectors are manufactured in Europe and meet the requirements of CE certification according to applicable safety standards. They offer a service life of up to 10,000 mating cycles, operate in a temperature range from -35 °C to +50 °C, and feature a dielectric strength of AC 3,000 V per minute.

For precise temperature monitoring, the connectors are equipped with an integrated Pt1000 temperature sensor according to DIN EN 60751, ensuring reliable performance even under demanding conditions. Thanks to their ergonomic design, lightweight structure, and flexible cable routing, the KW21A series provides comfortable handling and long-lasting reliability - ideal for modern DC fast-charging applications.
