These are designed for reliable performance, ease of handling & simplified maintenance and provides superior control & protection of medium voltage power equipment & circuits in utility, industrial, commercial installations involving transformers, generators, motors, feeder circuits and transmission & distribution lines.
It consists of manual/motor operated spring charged mechanism of stored energy type. In the closed state of breaker, the closing spring can perform the duty operation. Facility is also available for hand charging the springs in the event of control supply failure. The closing spring is charged in less than 15 sec. Electrical anti-pumping feature is also provided.
Indoor & Outdoor type Bypass panel for 11 KV & 33 KV servo stabilizer.
• Isolates AVR in Few Minutes

Indoor High-Voltage Air Break switches are based on a modular principle, which is suitable for the power system of 3.6 KV to 36 KV. They represent an attractive solution as a key breaking current for application in enclosed Switchgear, Ring main unit and compact substations. In combination with current limiting CT, IDMT Relay unit ensure control over the full range of over load and short circuit currents. It is used for Switching the Transformers, Capacitors, .protecting cables and overhead lines, etc.
