Voltage Protection Relays, RN-113

Novatek India Enterprises offers single-phase Voltage Protection Relays, RN-113. These are used for protection of single-phase loads, equipment and machinery against un-allowable mains voltage drops and fluctuations as well as against the consequences of neutral line cut-off. They can be utilised either as independent switching devices, or as relays operating with a magnetic starter (contactor). Advantages of the relays are wide voltage operation range and broad range of adjustable parameters, including auto re-closing time delay settings for the protection of machinery and installations with long-term transient dynamics, like refrigeration and compressor units. Features: voltage protection relay in enclosure for standard DIN-rail mounting; provide protection to any wattage loads – up to 7.0 kW – through its own changeover relay output contacts; over 7.0 kW (32A) – via contactor of appropriate rated power; and to avoid fault tripping of the power load in case of minor and/or short-term undervoltage a fixed trip delay is envisaged, that is activated when minimal voltage level threshold (Umin) value is reached. The principle of measurement of “running mean” voltage value is being used in present product line and this ensures highest protection level with accuracy and reliability of operation.
