Looking for advice to add a relay to a well pump timer. 1/2 hp 230v submersible @750’. The timer is rated at 10amp.

Does anyone have any recomendations?

Pardon the blunt reply What purpose do you need the relay for???
 
Manufacturer of the switch says that it is suitably rated however recommended a relay in between switch and pump
When you say "buffer" what exactly do you mean? reduce voltage current or what exactly?

Speak to Megawatt, via PM he is a fellow countryman, and a Master as well may be able to help you. he lives out in the sticks as well, so should be used to modifying stuff, never know until you ask

In the USA the UL-approved ratings for relays and relay-controlled outputs have both current and motor hp given for any unit, similar in intent to our resistive and inductive ratings. Although the 1/2 hp motor uses less than 10A, the fact that there's no motor rating shown, and the manufacturer suggests a relay, implies that the 10A is indeed for resistive loads only and the timer output relay might have a short life switching the motor load.

I'm not quite sure what the original question was: Any electrical control gear seller will have suitable contactors and enclosures; I don't know that there's any point in recommending a specific product.

I have to agree with Buzz what will be the purpose of adding a relay to a timer since the timer starts and stops the motor

Sorry Pete999 I agree with you on the actual purpose of the relay. Got ahead of myself my friend.

The timer will switch a suitable contactor/relay to control the pump. The 10A rating is likely to be a resistive rating and not inductive which would be much lower.
 
My guess is that he is having trouble with the current ratings of readily available timers,
And wants to use the timer to control a relay and the relay switchs the pump motor.
You can get heavy duty timers for just such functions,
Or if he rally wants to use a relay than I would go the whole hog and use a nice chunky contactor.
