High voltage ground fault relay LEG-191
Hikari Shoko Co., Ltd.
About This Product
■Features
・The inside of the relay has a plug-in structure.
- Highly noise resistant, with the ability to be unaffected by radio waves, surges, etc.
- Stable operation against changes in voltage, frequency, temperature, etc.
・It is a harmonic countermeasure product.
-The case has been changed to a resin case. The mounting hole dimensions are the same as the conventional products (LEG-171/172 series).
・Select the zero-phase current transformer (ZCT) from M41 to M240 or DM55 to DM100. All are compatible, so there is no need to match the serial numbers.
・This is an environmentally friendly product (compliant with the European RoHS Directive).
■Features
・Relay for earth fault protection of high voltage power lines.
・Compliant with "JIS C 4601 Ground Fault Relay Device for High Voltage Power Receiving".
