YES1-GP 250Amp 3-POLE Automatic Changeover Switch
The YES1-GP 250Amp 3-POLE Automatic Changeover Switch transfers your load from the mains to the generator, and back again, without anyone having to throw a switch., rated 250 A with 3 poles
About this part
When the mains fails, the generator controller starts the engine and the changeover switch moves the load across once the generator voltage is stable. When the mains returns, it switches back. The two supplies are never connected at the same time, which protects the generator and anyone working on the grid.
When to replace it
- Installing a new standby generator
- Upgrading a manual changeover to automatic
- A switch that no longer transfers reliably
- Increasing the size of the supply
Before you order
Mount the switch in a proper enclosure out of the weather, and test the changeover under load after installation.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
Questions
3-pole or 4-pole?
A 4-pole switch switches the neutral as well as the three phases. Your electrician will choose based on the earthing arrangement and local regulations.
Can I fit it myself?
No. Changeover switches connect to the mains supply and must be installed by a registered electrician.
