ROPT-20-3
Purpose
Starting Current Limitation Relay ROPT-20-3 with microprocessor management is intended for restriction of starting current at connection of inductive or capacitor loading to a three-phase network 380/220 B, 50 of Hz by means of the extinguishing resistors.
Design of system
– The ROPT-20-3 relay is executed in the case for installation on a DIN lath.
– On the forward panel of the module there are indicators "L1", "L2", "L3", "NETWORK".
– In the lower and top part of a product there are terminal blocks for connection of the relay to a network and to loading.
– Power supply of the relay is carried out directly from a controlled network.
