Product Details
Power relays enable the development of EV chargers with high-capacity output to achieve shorter charging time. Bringing the highest reliability, safety and energy-efficiency to EV charging, IVY's range of power relays offers durable solutions in compact footprints for fixed and permanently powered wallbox chargers. AC switching elements are a crucial part of safety and protection function in charging stations and cables. Key parts of the IVY line-up are the 40A IM-NE801A 2 pole power relay and 60A IM601 1 pole bistable relay. Which fulfill either IEC 61851-1 or the recent IEC 62955 norm.
IM-NE801A features a high-capacity resistive switching load rating of 40A@277VAC for 50K cycles (@32A 230V) or 20K cycles (@40A 230V). The relay also features a mirror contact structure (compliant with EN60947-4-1) which uses a 2 Form A contact arrangement. IM-NE801A has a normally open contact gap of 3mm, which makes this relay VDE0126 compliant with European photovoltaic standards and meets the 4kV surge breakdown voltage between contacts required to be compliant with the EN61810-1 Industry standard.

3. Product Application
EV-Charging is carried out via wall charging stations (wall boxes) or by using charging cables with integrated electronics (IC-CPD). Products that are used here must comply with current standards such as IEC62752 for IC-CPD mode 2 charging, or with IEC61851-1 for charging in accordance with mode 3 for wall boxes. These standards carry stringent requirement, for example with respect to the ability to withstand significant short-circuits.
Fortunately for hardware designers of EVSE systems, IVY's IM-NE801A power relay was developed specifically for use in accordance with IEC61810-1, more importantly, to meet the exceedingly stringent short-circuit withstand-current requirements of this standard.
