Question on ice cube relays. Correct me if I am wrong

If I use a 3 pole ice cube relay with 120VAC coil voltage does it mean I can only wire 120VAC components?  Can I have a three pole ice cube relay with a 120VAC coil and wire different voltage components to each pole?  Ex: wire 480 to one pole, 208VAC to the 2nd pole, and 24VDC to the 3rd pole as long as I have access to the voltage source? 

If I am wrong please correct me.

 

Thank you

When you talk about coil voltage, that is the voltage that the relay ideally should receive when you energize it. Although the relay may be able to be powered with less voltage, its set voltage, ideally, the relay should receive its rated coil voltage for standard operational use. Do not use a voltage higher than the rated coil voltage. Too high of a voltage may damage or destroy the magnetic coil, whereas too little voltage may not give it not enough power to actuate. It's best to use a value near or between its rated coil voltage and its operate voltage.

You need to check the voltage and current ratings on the contacts, if you meet the specifications then yes. However, it is probably not a good idea to mix high and low voltages on the same relay, if there was a problem you may end up with 480 V on a 24V DC circuit. If this is in a domestic wiring installation, there are probably wiring regulations that cover this issue. My guess is that they do not allow ELV circuits to be on the same relay as mains voltages, and I certainly would not do it,

I'm not wiring 480, i was just using it as an example. I'm using no more than120vac.

All the same, wiring regulations may not permit the mixing of ELV and mains voltages on the same relay, you really need to check the regulations for your country. As I have said in previous comments, you may invalidate things like insurance if there is a fire and the wiring is found to be at fault. Personally I would not do it, but that's up to you.
You will find that the relay contacts have a much lower rating for DC as well, which is why you need to check the specs carefully,

I attached a photo of a 3 pole ice cube relay. The marking with the red line is the coil voltage which means that i need to supply 120VAC to the coil in order for the switching mechanism to do what it is designed to do. Now, the ratings that is circled i can't really comprehend. I looked online and didn't get and good explanation, but this is what I'm taking it. Correct me if I'm wrong.

I am able to supply 120VAC-240VAC to each set of contacts without exceeding the total maximum amperage (12A) OR I can suppy 28VDC to each set of contacts without exceeding the total amount of amperage (12A). For the amperage rating, is that 12A per set of contacts or the total amount of amperage between all set of contacts combine? As for the 1/3 & 1/2HP ratings, i don't understand. Am i correct or wrong? I really do appreciate your knowledge Richard.

It should be per contact.
The horse power rating is supplied for those using motors on the contacts, motors can draw may be 5-10 times the running current on startup, until they get up to speed, so the contact ratings must take that into account,
