Contactors for e-brew heating elements.

[Windsors]

Just received 4 of the C-23-01's. They are perfect. Thanks Paul.

Glad they worked out for your build. Send pics when your finished.

Paul,

Here are some pics of the panel I built with the contactors I got from you.

Inside. Contactors on the bottom.

Thanks for the parts!

Thats a sweet looking panel, great job!!!

 

[zeus53219]

Paul,

Looking at the pics, what are you using to latch your main power? Are you plugging in hot? If so I have a C43 with power switch that would work sweet with this set-up.

Forgive me if this is the wrong place to ask, but still don't understand what contactors are for. I know you said they pull a coil when you flip a switch, but why cant you just use a 240V rated toggle switch and bypass the contactor? I am looking to make a simple 240V system and I don't want to miss a good deal before they are all gone because of my arrogance!

EDIT: I have been trying to read up on the use of these and it seems like it is a safety measure which would allow you to physically disconnect both hot lines from the element as opposed to a simple switch which would only disconnect 1 hot line leaving 1 hot line on the element. However one could get a 2 pole (if that is correct) switch that would disconnect both lines correct?

Disclaimer: I'm a novice at this. A contactor is like a relay, except designed for higher current ratings. That is, it is an electrically controlled switch. The idea is that you have a circuit with a much lower power level that you use to control a much higher switched circuit. So, for this application (your brewery), the switch on your control panel THAT YOU TOUCH will be the lower power one and it is ued to switch (via the contractor) the higher amperage 240vAC circuit. Quite simply, it is a safety device, but not only for the reason you stated above.

I got more contactors in today. So for those of you that are waiting I will ship out first thing in the morning. After all orders are satisfied, I will have about 15 left.

 

[lud]

Zeus...what's the control voltage? Thanks man.

 

[zeus53219]

Control voltage I currently have are mostly 120v but I believe I still have 4 24v dc units available.

 

[drez77]

I have 4 of the contactors from zeus and they all work perfect.

 

[danbass]

I've got 5 from Zeus and I can't speak highly enough about him. I use one for a 50 amp main, and then I have two that I use to switch my RIMS and my BK elements from 110 to 220.

 

[TravelingBrewer22]

I'd like some but I'm not sure how many. I'm going to be running a bk and holt with 5500w 240v element in each and. rims tube with a 1500w 120v element. can u pm me with suggestions and payment info? thx

 

[Maltose]

Just ordered one 43 and two 30's. Paul was very helpful piecing together my system. I may go with a 65A system to run two 5500w elements while also running my brewtroller and two chugger pumps. My build thread will be updated when it all comes together. Thanks again Paul.

I haven't done a build yet (Paul's contractors look good sitting on the shelf). I am planning on doing 1 for each element, plus one for the input main. A C30 will work for each 5500w 240vAC, if you are planning larger than a 30AMP concurrent draw, you would need something higher capacity on the main. Dunno on the 1500w/120vAC, should be able to find 15 AMP 120vac relays pretty cheap?

 

[zeus53219]

Sorry guys if I didnt reply to some of your PMs today, got busy at work. I will reply soon. But for now here are some of the pics I promised. Still not 100% complete on the move from the garage to the basement, but doing the 3rd indoor batch tomorrow.

Can you discuss/show a wiring diagram for this?
Thanks.

Alright, I don't have much time to draw out a wiring diagram this evening, but I'll do my best to describe what I wired up.

First, they are both 110v coils. So I have an On/Off/On switch for each pair. Left on sends power to the left contactor (110v) and right on sends it to the right contactor (220v).

On the input side, I'm only using two of the three contact points. On the two 110v contactors, I bring in and jumper across the neutral for input 2. On the two 220v contactors, I bring in the second hot and jumper across on input 2.

I bring in the other hot from an SSR to input 1 (jumpered across the input sides). The circuit is closed only when the SSR is on, either on the 110v or 220v side.

On the output side I jumper outputs 1 & 2, send to the outlet, and run the ground directly to my post.

Actually, here's the image.

I'd like two with the 120v coil if you have any available, shipping to 84081.

 

[zeus53219]

PM sent, picked up more yesterday.

PM sent with my contact info, hoping I can explain what I'm looking to do and you can confirm what I need.

 

[jlachesk]

Hey Zeus,

You mentioned having a/some contactors with switches that would work well for main power. Any of those available, and do you have any more info/pics? Trying decided if I like that solution more than another 120v coil contactor + switch.

Thanks.

I don't have any contactors with built in switches. All you need to do is run the 120v through a properly rated on/off switch to pull in coil for main power. I am using a keyed switch so that the panel can be locked out when not in use. I do have AB 120v key switches available for sale, but they are pricey at $55. You can find switches all over the net for much cheaper.

Just give a call, we will figure it out. PM sent with info.

 

[jlachesk]

Fair enough, that was my original plan anyways. Thanks, Zeus.

 

[zeus53219]

All contactors that were ordered are shipped out. There are a limited amount left, let me know how many you need.

 

[zeus53219]

10 more available.
