To get a signal at undercurrent, the current must first reach a value higher then reset value / hysteresis to activate the relay. On the overcurrent relay AI 838 the scale is adjusted to the response value. When the current exceeds the setting value the relay switches on. The contact resets, as soon as the current goes under the setting value x hysteresis,0,5 ... 1 A 4 ... 8 A 0,8 ... 1,6 A 6 ... 12 A 1,5 ... 3 A 8 ... 16 A 2,5 ... 5 A 12 ... 25 A 50/60 Hz or DC RW ≤ 5 % or DC RW ≤ 48 % (please state when ordering) Extension of measuring range: for current > 25 A AC: with current transformer 5 A type Setting range on relay 2,5 ... 5 A Load capacity 18 VA Class 3 DC: Connect shunt in parallel to measuring input 12 ... 25 A The table is only valid when Nominal current Measuring range the wire between shunt and of shunt relay has a resistance of 25 A 21 ... 42 A approx. 0,5 mΩ (equivalent 40 A 26 ... 53 A to a copper wire with 0,3m 60 A 33 ... 67 A length and 10 mm2 diameter) 100 A 45 ... 95 A and the ambient temperature 150 A 63 ... 130 A is 20 °C.
