Conformally the EN61243-5 standard, if any phase voltage is above 0.45Un the related display turns on and the relat output becomes active. If the phase voltage is below 0.1Un then the related display will turn off. If all phase voltages are below 0.1Un then the relay is off. The unit is polarized to ground and does not carry hazardeous voltages. For verification, divided voltages are also available on the front panel test terminals. The unit will come together with its watertight gasket for test terminals and panel installation. Units are specially manufactured for usage conditions. Together with the order, the capacitive isolator value (pF) and the busbar voltage should be specified. The relay version’s power supply is an isolated switchmode and does not polarize the DC busbar.
