800A is an awful lot! Relays are a poor choice for switching inductive loads like motors because you will get arcing at the contacts. I've tried designing a snubber, but it can be very, very difficult. Go with MOSFETs. |

| Well i think that Relay is Best Solution for you, | 01/01/70 00:00 | |
| Not suitable - no speed control! | 01/01/70 00:00 | |
