YES1-GP 630Amp 4-POLE Automatic Changeover Switch
YES1-GP 630/4P is an automatic transfer switch (ATS), rated 630 A with 4 poles for standby generator installations.
About this part
An automatic changeover switch turns a generator into true standby power. It is sized by current (amps) and number of poles: 4-pole switches also switch the neutral, which many installations require.
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
Size the switch to the main breaker of the supply it switches, and choose 3-pole or 4-pole according to how the neutral is arranged at your installation. Changeover switches must be installed by a qualified electrician who issues a certificate of compliance.
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.
