Once AC power from the Generator is sensed by this transfer switch, it will start a timer and automatically switch over to generator power supply after a 20-45 sec delay which ensures the generator has sufficient time to run up to speed before electrical load is applied.
|
Double protection of built-in mechanical interlocks and control circuits prevents two separate 120/240 volt AC power sources from entering the AC distribution board at the same time and causing a short circuit.

The coating process used on the surface of this transfer switch can be waterproof, rust-proof and anti-corrosion, and can effectively prolong the service life of the product.
