AHER2281

AHER2281 is a HE-R series power relay. It expands the existing line of general power relays with low coil-holding voltage for reduced power consumption. This relay is PCB mounted with two contact arrangements for easy board assembly. This HE-R series relay allows for the cut-off of all 3 phases plus neutral simultaneously and meets the necessary short circuit current rating (SCCR) to pass UL and IEC standards for EV charging equipment. With its high capacity switching and carry current capability, mirror contact structure, and welding detection function, this relay is suitable for various applications in industries such as electric vehicle charging, industrial, power generation, and solar.
