CHARX protect – surge protection for charging stations and home chargers

Surge protection for charging stations and home chargers

With CHARX protect, you can protect charging stations and electric cars against damage from surge voltage caused by lightning strikes or switching operations in the grid. We can provide you with various protective device types for a comprehensive protection concept to ensure that your charging infrastructure remains available at all times – at any time of the day or night, and in any weather.

Charging without risk With our comprehensive protection concept

A charging station for electric vehicles is as complex as the vehicle itself: From the power supply and the charging controller to the cables for Ethernet communication, there are many sensitive components. They need to be protected to ensure a long service life and that the charging process is uninterrupted. A comprehensive protection concept therefore consists of three areas:

Feed-in protection: Type 2 protective devices and type 1+2 combined lightning current and surge arresters protect feed-in against dangerous surge voltages that may be caused by lightning strikes and switching operations in the grid.

Protection for 12 and 24 V devices: With type 3 surge arresters, you can ensure the long-term function of the numerous sensitive components with 12 or 24 V supply voltage.

Protection for communication: Components for communication are usually connected via Ethernet and should also be protected.

The retrofit solution for home chargers CHARX protect retrofit

Even though the main distribution box already has surge protection, the protective effect is often insufficient for long lines to the home charger. Due to its weatherproof and shockproof IP65 housing, CHARX protect retrofit can be easily installed in a carport under or even next to the home charger.

The integrated type 2 protective device reliably protects home chargers with charging powers of 11 to 22 kW and the connected electric vehicles against expensive damage due to voltage peaks that can be caused by lightning strikes or switching operations in the supply grid.

To match the existing cable routing, the feeding AC cable can be fed into the housing either at the top or at the bottom. Internal wiring is particularly fast with the push-in connection.
