The BA9053 / 410 current relay is a static measurement relay with isolated measurement and auxiliary circuits. It is suitable for monitoring direct and alternating currents (compensated to effective value). The response value is adjusted, and the fallback value is adjusted by hysteresis. The device operates as an overcurrent relay with adjustable time delay, but can also be used as an undercurrent relay (as per IEC 255, VDE 0345).
