Which switch for my motor?

[Kidds]

I am fitting a new motor to work my hydraulic pump.
The motor is 1.5kw single phase, it works a hydraulic pump which operates hydraulic rams on my bulk bin tipper.
It seems a big motor to me so I am assuming it needs something more than a 3 pin plug into a socket.
Could anyone tell me which on/off switch to get for it please.

I think this would suit;

But you need the correct overloads to go with it.

Thanks for the reply.
I had looked at that one earlier but the reviews are pretty bad and say there are more parts required on it in order for it to function.
I’m capable of fitting the parts required but not without a wiring diagram and knowing which parts.

Take no notof the reviews, you will need an overload relay to match the current rating on the motor:

A 3 pin plug is good for 3Kw so you should be ok and the wiring will be fairly straight forward but it should come with a drawing.

Depending on the speed.
Brook motors quote @3000 rpm 5.25 amps
@1500 rpm 6.3 amps
@1000 rpm 7.6 amps (unlikely for yours)

The overload 9574G will cover the first two motors,

13a plug certainly up to the job, if you don't want motor protection then an isolator switch in circuit such has this could be handy.

Provided it has no load at start up 3 poin should handle it. We had many similar motors on augers as a kid , but there was a lot of dodgy wiring then and the odd shock too

Do you mean I could turn the motor on and off just using that rotary isolator?
There is no load on the motor at start up and it runs at 1500rpm. It is connected to a hydraulic pump that just circulates the oil until a spool lever is operated. Will run for a minute or two before being switched off again, it is for my bin tipper so tips the bin up, then another ram opens the door, the apples come out and it is turned off again until the next bin is needed which will be at least half an hour later.

Much like a grain auger motor it should start fine on a 13a plug. Always better policy IMO to use a proper starter with overloads to cover the day when something unexpected happens

 

[Netherfield]

Yes you could turn the motor on and off with that switch, you might even get away with a 5a fuse in the plug if you're starting under no load.

 

[Kidds]

I got a proper starter switch yesterday, I don't understand the wiring diagram that came with it but with online diagrams and looking inside one I have on another machine I can figure out what goes where.
Thanks for the replies.

Including overloads?

Yes

To put things in perspective a cheap 9 inch grinder is 1800 watt/1.8kw, a good one is 2200watt or 2.2kw. They are both fine on a 13amp plug.
