How many Mirror heat pads on a 12ch relay

As the title says how many mirror heat pads can I put on a single channel of a 12ch 10a din relay. Would I work it out like a halogen bulb 5 x100w heat pad = 500w. 500w / 230v= 2.17a. Or is it different becaus it is heat.

Also would it matter if say 1 pad was 60w and 4 were 100w on the same Channel. Obviously the calculations would be differnt.

 

Hi 160MCM
There is a table for the load types in the manual for the relay.

Mirror heaters are resistive load.
Your calculation is correct and you can simply add the individual heaters current to get the total for each channel.
You can see in the instructions Clipsal claims

But if it were me I would still try to keep the current on each relay quite a bit less than the maximum rating to extend the life expectancy.

 

Thanks for your reply I thought I remembered reading the ratings somewhere but was not 100% sure. I should be fine with my 2.17a load on my 10a channel

 

Yes the relay will handle 2A of resistive load without a problem.
