 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm  or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm². On the front panel there are two switches to set upper “U_phase>” and lower “U_phase<” thresholds, regulator of actuation time “t”, two red indicators of net error “U>”, “U<“,  yellow indicator of built-in executive relay ““, three red indicators of availability phases “L1”, “L2”, “L3”.

 Upper “U_phase>” and lower “U_phase<” thresholds are setting by using potentiometers, that located on the front panel.A delay of actuation relay is exhibited by medium potentiometer. When power is applied, if a delay is setted and all controlled parameters are normal, the relay will turn on at the end of the counting delay time t, and relay contacts 11-12, 21-22 will be open and contacts 11-14, 21-24 will be close. A flashing indicator “” signals about the counting time delay actuation at which the end of it the buil-in relay switches. At a deviation of one of the parameters of the nominal value, turn on the indication of error and relay switches off after the end of delay. Upon returningthe controlled parameter to normal, the indication of error is switched off immediately, and the relay switches after the end of actuation delay. At loss of all three phases a relay turns off without counting delay of actuation time set the user.

• In case of availability of all phases all three indicators turns on
• In the absence of any phase will turn off  the appropriate indicator «L1», «L2», «L3».
• When the neutral wire breaks, indicators «L1», «L2», «L3» have little noticeable glow and indicators «U>», «U<», «» is turned off.
• When you connect the neutral wire to one of the terminals «L» for connection of phase, and phase to terminal «N»,turns off the appropriate indicator «L1», «L2», «L3», indicators «U>», «U <» will be turned on.
