Over-current monitoring relay TCC-W series

under-currentDPCOAC/DC

- LED indicators for power supply, contact and reaction timer On application of the supply voltage with N.O. Mode selected, the output relay pulls in and the timing period ts starts. Current control with no latch (auto reset) function At the end of ts, if the measured current exceeds the window in either direction, timing period tr starts. At the end of tr, if the measurement still exceeds the setpoint the output relay changes over. The output relay resets immediately, when the monitored current reaches the hysteresis set value. Current control with latch (manual reset) function At the end of ts, when the measured current exceeds the window in either direction, timing period tr starts. At the end of tr. if the measurement still exceeds the setpoint the output relay changes over and remains in this condition, even when the measured current reaches the hysteresis set value. An external reset (S1) must be operated to reset the relay. supply voltage variation - nominal voltage +10% / -15% frequency range - 48 - 63 Hz duty cycle - 100% start surge delay - 0- 10s reaction time - 0-5s reset time - < 100ms
