3-phase voltage relay 230/400V AC type: PNM-32 EXT10000106-WPL

Voltage relay PNM-32 for voltage value control and protection of three-phase receivers. The user can program the minimum and maximum value of voltage, hysteresis, asymmetry and the delay of switching on and off. The system detects voltage unbalance and wrong phase sequence. LCD display and keyboard enable visualization of network parameters and easy programming.
