The HE-R relay’s rigorous testing includes IEC62955, a 10kA short circuit test, which means that customers can now specify their 22kW wallbox for up to 32A @ 10kA short circuit current, providing a high level of protection for EV charging equipment.
In addition, the smaller HE-S relay now conforms to the IEC62955 standard for 3kA short circuits. This feature allows customers to use the HE-S series for wallboxes rated at up to 16A, offering greater flexibility in the selection of charging equipment for a wide range of applications.
