Featured Product : AMERICAN ZETTLER AZSR131 – 35amp MINIATURE POWER RELAY
AZSR131 relays from Zettler for use in E-mobility wallbox charger.
Global plug-in electric vehicles sales are projected to reach 12 million units in 2025, and 21 million in 2030.
This positive trend is also evident in associated sales of charging infrastructure solutions. In particular, wall charging stations – so-called “wallboxes” – that enable EV charging with AC voltage according to charging mode 3 (IEC 61851-1) are and will continue to be in extraordinary demand. They facilitate charging of electric vehicles with voltages up to 400V, and are used in protected areas such as parking garages, carports or private homes.
A supplier of wallboxes contacted ZETTLER in Europe, because of their need for a relay compliant with the requirements of IEC 61851-1 for a new generation of EV charging wallboxes. The relays of ZETTLER’s AZSR131 (click here for more info) series have a normally open contact (1 form A) and are UL and TÜV approved with 35A 277VAC and 30,000 switching cycles or 33A 277VAC and 50,000 switching cycles with TÜV. The relays are available in the standard version with 1.8mm contact gap and in a special version with up to 2.3mm. The relays are also available in a version in accordance with the extended household appliance standard IEC 60335-1 (GWT). This component solution in the EV charging space along with others, such as the new AZEV132 EV charging relay, keeps ZETTLER relays at the forefront in this significant green energy growth segment.
