Digital Earth Leakage Relay
Digital Earth Leakage Relay
Venkat Switchgears, an ISO 9001-2008 certified company, offers Digital Earth Leakage Relay, VT-3020 Series. The company, since 2002, has worked with an indomitable objective to be the leader in design, development and manufacturing of MV switchgear (i.e., VCBs and LBS), and MV and LV panels. With the expertise, the infrastructure and best business practices acting to its advantage, it has in a short time stretched the very limits of possibility, with the onus on quality and efficient process in delivering effective deliverables.
- Earth leakage protection for generators, transformers, feeders and motors
- Frame leakage protection for switchboards and LT control panels
- Scheme where protection from earth leakage is required and in general electrical distribution systems
- Earth leakage protection in mining, oil refineries and chemical industries)
- Input auxiliary voltage – 110/230 V AC 50 Hz
- Leakage setting range variable – 30-240 mA (in steps of 30 mA), 50-400 mA (in steps of 50 mA), 1-4 A (in steps of 0.5 A), 1-8 A (in steps of 1 A)
