Monitoring relays three-phase voltage EL-10-1УЗ is designed to protect electric motors, thyristor units and other consumers of three-phase current when unacceptable lowering of the symmetrical voltage and asymmetry of phase-to-phase voltages in a reverse phase sequence, as well as for use in control systems.
Relays are made in the version you Have (for operation in macroclimatic regions with temperate climate) and in the performance of T (for operation in macroclimatic areas with both dry and humid tropical climate) and must be operated in closed premises with natural ventilation without artificially controlled climate conditions (class 3). Only for export performance.
Operating conditions
• ambient temperature:
• for moderate climate— from 228 To 313 K (from minus 45 to plus 40 °C);
• for tropical climates — from 263 to 318 K (from minus 10 to plus 45 °C);
• relative humidity not exceeding 90 % at a temperature of 298 K (25 °C);
• atmospheric pressure 8,6-104 — 10,6-104 PA (650-800 mm Hg.St.);
• vibration in the range of 1-100 Hz with acceleration of 9.8 m/S2 (1 g).
• Relays are manufactured in two versions:
• ATE-10-1—with time delay;
• ATE-10-2 — without time-delay.
• Relay position — arbitrary.
Relays are installed with front connection wires when serving the installation.
Specifications
Rated voltage:
frequency 50 Hz— 100, 110, 200, 220, 300, 380, 400;
frequency 60 Hz 220, 380*. Allowable voltage fluctuation from the nominal value +10 -15%
Relay is triggered when:

• the loss of one, two, or three phases;
• applying relay three-phase voltage with inverse phase interleaved eat;
• symmetrical voltage drops to values equal to 0.75 and 0.7 nominal.
The response time of relays,
• shutter (ATE-10-1) 5±1,5
• no exposure (ATE-10-2) 0,005—0,2
