Product Details
IM-NE801A is specially designed for the EU/USA Standard Charging Station to replace the traditional AC contactor and reduce the large space needed for installation.
It's main features as follow: Continuous Current: 40A; with Contact Form:2A; Dielectric Strength Up to 4000VAC; Low Temperature Rise; Sealed Structure to Resist Harsh Environment; UL Certified, IEC61810-1 Compliant. The relay has short-time overcurrent characteristics, can withstand three times of 1000A 1ms overcurrent, and the contacts will not be damaged, and can continue to work normally to open and close.
MD20STA-C is an AC/DC leakage sensor that complies with the UL2231-2 standard, and its leakage protection type is CCID20. The AC leakage protection threshold is 15~20mA, and the DC leakage protection threshold is 40×1.414=56.56mA. It also protects against mixed leakage current and high-frequency leakage. When the leakage current in the line reaches the above alarm threshold, it will output a leakage alarm signal (OC gate output). In addition, it has a self-test function, which can be used to determine in real time whether the sensor is in a normal working state. If the sensor fails, the self-test output terminal will not be able to output the self-test feedback signal (Open Collector Output), so this leakage sensor will be safer and more reliable in the field of leakage protection.

The main advantages of IM-NE801A lie in 1.5*2=3mm conntact gap:
Its contact distance can be up to 3mm, and the contact spacing of the general relay is about 0.8mm or 1.5mm. In some ways this feature made contact between medium pressure can improve a lot, the higher the withstand voltage value, and also solve the problem of contact resistance increase rapidly, etc, under non-operation status it can avoid wrong operation or damage caused by external factors. which improves the tensile arc resistance of the contact and prolongs the service life of the relay.
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 ICCPD 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.
IM-NE801A relay is two-pole power PCB relays that have been specially developed for e-mobility applications and the extremely strict short-circuit strength requirements of the associated standards like IEC62955, IEC62752 and IEC61851-1. The relay is approved at UL, CUR and TÜV with ratings of up to 40 A, with 20000 cycles @40A 230VAC on-off ratio 1s:4s resistive load 50000 cycles @32A 230VAC on-off ratio 1s:9s resistive load
