it's an isolator, duh!
a switch and fuse, capable of handling 30amp of electricity at 415 volt, and with 3-phase connections 30A, 415V, 3-phase isolator - what machine is equipped with that? an AHU? a 4 bar air compressor? a 10hp sewage pump? This post has been edited by lucifah: May 10 2008, 12:21 AM |

What is the different between 1 phase connections? a switch and fuse, capable of handling 30amp of electricity at 415 volt, and with 3-phase connections 30A, 415V, 3-phase isolator - what machine is equipped with that? an AHU? a 4 bar air compressor? a 10hp sewage pump?   |

I think this is what you wanted to know.
If you're buying a house.. 1-phase = those lower voltages power 3-phase = provide more power source .. which means support more airconds etc. edited: misunderstood the concept. thx lucifah This post has been edited by tzyy: May 11 2008, 02:17 AM |
