Vacuum Circuit Breaker By Easun Reyrolle Ltd.

We are the largest manufacturer and supplier of Vacuum Circuit Breaker in Hosur, Tamil Nadu, India. iCB series comprises embedded pole type vacuum circuit breakers for medium voltage and indoor use. They are suitable for three phase AC operations for 12kV, 17.5kV, 24kV and 36kV and are used for the protection of the electrical equipment in various industries, mining, and especially for medium voltage distribution sub stations, together with suitable air-insulated cubicles.

The iCB used German Technology and is available in complete series for medium voltage and for all commonly used rated currents, from 630A to 4000A, and for rated breaking current up to 40kA. The iCB circuit breaker come with a mechanical lifetime of 30,000 operations.

The embedding with epoxy resin covers the vacuum interrupter as well as the upper and lower contacts of the circuit breaker, thus creating a full insulation for the internal electrical circuits. The embedding is done with a fully automated process, the APG (automated pressure gelatin) process. Thus, the iCB is no longer subjected to environmental hazards, and is fully maintenance free in this aspect.
