Single Phase Change over

Automatic Changeover Switch (Single phase) between Mains and Generator supply.

Mains Input - 1 phase - 140 v – 340 v, Generator Input - 1 phase, Output - 1 phase.

Load – 32/63/100/150 Amp. When main supply fails the load will shift automatically to Generator supply and as and when Mains Supply restore the load will shift to Mains Supply and Generator will become unloaded. Silver points Relays are used in relay for excellent performance

Three Phase Change over

Automatic Changeover Switch between 3 phase Mains supply and 3 phase Generator supply (Load – 100 Amp). When 3 phase Mains fails the load will shift to 3 phase generator supply automatically and as and when mains (3 phase) restores, the load will shift to Mains Supply automatically and Generator will become unloaded. It, works as a Single phase preventer also, if even one phase fails the load will shift to Generator supply, and the load will come back to Mains Supply as and when all the three phases restore. Silver points Relays are used in relay for excellent performance.

Phase Selector

This model is very useful for Homes and Shops. This is an Automatic Phase Changer where mains input is 3 phases and Generator input is 1 phase and the load is divided on all three phases. When even one phase fails or two phases fails the Changeover will give the supply on all three output Terminals automatically. When all three phases fails the total load will shift to Single Phase Generator supply. The Single Phase Generator will give the supply on all three output terminals, without doing any exercise and as and when Mains restores, even one phase, the load will shift to Mains from Generator automatically. Silver points are used in relay for excellent performance. Please use this model for single phase equipment’s only.
