            EVR Series AC Power Relays
                    Littelfuse EVR series AC power relays are designed to switch EV charging applications on and off
    

Littelfuse EVR series printed circuit board (PCB) two-pole (2P) AC power relays are designed to switch EV charging applications on and off. Their 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 of 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.

Features and Benefits

Low contact resistance: low-temperature rise at rated current
Contact rating up to 40 A: suitable for Mode 2 and Mode 3 EV charging defined by IEC 61851-1 and AC Level 2 EV charging defined by SAE J1772
Meets requirements in IEC 62752, IEC 62955, and UL 2231: single form factor supports global standards and simplifies inventory
Certified to IEC 61810-1: enables compliance with IEC 61851-1 for switching of main current path

Contact load category CC 2
50,000 cycles at +85°C (+185°F) for 35 A load
Mirror contact mechanism, according to IEC 60947-4-1: enables detection of power contacts welding
Contact gap > 3 mm: meets overvoltage category III requirement and provides enhanced protection against shock and vibration for added safety and longevity
