Product Description
BSF Manual Changeover Switch
BSF series modular changeover switch is a new generation of power changeover switch independently developed by our company. It realizes dual power switching up to 63A with only the size of mini circuit breaker case, which has the advantages of small size, high cost efficiency, high reliability, long life and easy installation.
A changeover switch switches a house's electricity supply from the general grid power supply to a "generator system" in case of power outage. The changeover switch connects to the main power grid, generator or alternate source and the house wiring. When you switch or "Change over" all the power on that circuit changes from either Grid or Generator.
