The EVR-2A24-1 is a printed circuit board (PCB) two-pole AC power relay designed for switching EV charging applications. It has a contact rating of 40 A at 277 V AC with a contact gap greater than 3 mm for enhanced isolation. The relay features PCB terminals, a compact form factor, and a coil voltage of 24 V DC with a coil resistance of 306.4 Ω and a power consumption of 1.88 W. It meets IEC 61810-1 (CC2), IEC 60947-4-1, and is certified for overvoltage category III with a functional shock resistance of 98 m/s² and vibration resistance up to 55 Hz at 1 mm double amplitude. The relay has a mechanical life of 1 million cycles and an electrical life of 10,000 cycles at 40 A and 85 °C. It weighs 65 grams and is RoHS compliant. Dimensions are 36.0 mm × 30.0 mm × 22.9 mm.
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.
