Control relays Current detector control relay Description The WI current detectors are electronic devices with an output relay that is connected or disconnected, in accordance with the level of current detected in the circuit. }} trip level is adjusted with the potentiomThe eter on the front of the unit. }} The reset process is automatic with currents under 10% of the trip level (Hysteresis). }} Delay: the connection and disconnection times of the output relay can be adjusted separately. }} Measurement of the current, depending on the type: yy With built-in current transformer (net diameter ∅ 25 mm) yy Separate transformer, input.../5 Aac Features Power supply circuit Voltage* Testing voltages between the circuits and the grid Measurement circuit Relay contacts Output relay Insulation voltage (Ui) Interrupting power (105 operations) with resistive load Ue/Ie: 240 Vac / 3.2 A with inductive load Ue/Ie: 240 Vac / 0.8 A 30 Vdc / 1.6 A Build features WIs can be used in any application that needs to control the load: Operating temperature Standards IEC 605, IEC 1010-1, EN 61010-1, EN 50 081, EN 50 082, IEC 255, UL 94, UNE 20 607, UNE 21 136, VDE 0110 (*) Other voltages and frequencies on demand. }} Power supply units for grinders or aggregate grinding units. }} Loads in extrusion machines }} Pump control }} Load on motors, etc.
