Pentagon Switchgear offers HV switchgear panels in metal clad enclosure, fully extensible and with horizontal draw out vacuum circuit breakers (single/multi line up). These breakers protect the power transformers, HT capacitors bank, generators and feeders. These breakers are also used for starting the HT motors and auto reclosing duty. They consist of manual/motor-operated spring charged mechanism of stored energy type. In the closed state of the breaker, the closing springs can perform the duty operation. Facility for hand charging of springs in the event of supply failure is also available. The motor charges the closing spring in less than 15 seconds. Electrical anti-pumping feature is also provided. The mechanism is trip free and suitable for rapid re-closing. The vacuum interrupters are capable of switching capacitive currents and small magnetising current.
