Product description
Ground fault monitoring relay Selec 900ELR-2-230V-CE
The 900ELR-2-230V-CE analogue ground fault monitoring relay from Selec for 1 and 3-phase systems monitors ground fault current. The switching hysteresis and a possible time function can be easily set via the LCD display with backlight. For an alarm output, you have two NC or NO contacts available. The 900ELR-2-230V-CE ground fault monitoring relay with a supply voltage of 230 V AC is designed for simple DIN-rail mounting and can be quickly wired via the screw terminals.
