This relay can replace conventional contactors, offering the advantages of reduced space requirements and lower installation labor costs. It is particularly well-suited for applications demanding high reliability, such as PV/ESS inverters, fast EV chargers, and power supply/UPS systems. The relay's reliable auxiliary contact can expedite the replacement of contactors with PCB relays. This high reliability is a crucial factor for use in systems requiring high operational safety. Designers can replace conventional contactors with auxiliary contacts using this relay with fewer design modifications.
