As the recognition of EVs spreads and their adoption progresses, the challenges are also becoming apparent. Compared to internal combustion vehicles, issues such as the cost of batteries and the need to lighten the vehicle body to extend driving range are becoming more evident. Additionally, safety concerns, such as the risk of fires during collisions, are attracting attention. As a relay manufacturer, we have developed the "ER250" as our solution to these challenges faced by automotive manufacturers regarding EVs. The "ER250" adopts a structure that does not use ceramics, which are commonly used in general relays, making it a more compact and cost-effective product. Furthermore, through our unique contact structure, we have achieved the world's best short-circuit withstand performance of 20kA. Additionally, by employing a hinge structure, which is our specialty, we have also achieved the world's best shock resistance performance for automotive high-voltage DC relays of 1000m/s². 【Features】 ■ High short-circuit withstand (20kA) ■ High current conduction (250A rated current) ■ Compact size ■ High heat resistance ■ Plastic seal structure ■ Lead-free compliant *For more details, please download the PDF or feel free to contact us.
