The EVR-2A09-1 is a printed circuit board (PCB) two-form-A ac power relay designed for EV charging applications, switching up to 40 A at 277 V ac. It features a contact gap greater than 3 mm, PCB terminals, and a compact footprint measuring 40.0 mm × 30.0 mm × 22.9 mm. The relay has a 9 V dc coil with a nominal power consumption of 1.88 W, contact resistance of 100 mΩ max, and is rated for 50,000 electrical cycles at 35 A and 85 °C. It meets IEC 61810-1 (CC2), IEC 60947-4-1, IEC 61851-1, and SAE J1772 standards, and is certified by TUV, CQC, and cURus. Weight is 65 grams, and it supports overvoltage category III with functional shock resistance up to 98 m/s² and vibration resistance from 10 to 55 Hz at 1 mm amplitude.
The EVR Series printed circuit board (PCB) two-pole (2P) ac power relay is designed to switch EV charging applications on and off. Its extended contact gap of greater than 3 mm provides better isolation and allows for usage in higher elevation environments. The very compact form factor has a low temperature rise and heavy-duty power switching current up to 40 A/277 V ac. This relay family enables compliance with all EV charging infrastructure standards such as IEC 62955, IEC 62752 and UL 2231.
