The EVR-2B09-1 is a printed circuit board (PCB) two-pole ac power relay designed for EV charging applications, featuring a 2 Form A, 1 Form B contact arrangement with a 9 V dc coil. It switches up to 40 A at 277 V ac on Form A contacts and 1 A at 277 V ac or 30 V dc on Form B contacts, with a contact gap exceeding 3 mm for enhanced isolation. The relay has PCB terminals, a compact footprint, and operates with a class F insulation system rated to 155 °C. It meets IEC 61810-1 (CC 2), IEC 60947-4-1, and IEC 61851-1 standards, and is certified by TUV, CQC, and cURus. Dimensions are 40.0 mm × 30.0 mm × 22.9 mm, weighing 65 grams.
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.
