If contacts are rated at 6A non resistive, what KW will they switch?
At what voltage? I'm guessing mains - so 240 AC. If that is the case, then they'll switch 6x240 = 1440W (1.4kW).
Power = voltage * current.
It depends entirely on the voltage.
Volts * amps = watts (for a resistive load)
If you mean at mains voltage then the answer is:- 6 * 230 which is 1.38kW
(BTW I assume you mean 'resistive' not 'non resistive')
At 132Kv, a tad shy of a megawatt....
Yes, for DC. I'm talking 240ac
Yes, thanks all. I was talking 240vac.
Thanks for the answers.
Still works for AC: P=V(rms) * I , but for resistive loads only.
Thank g for that! I thought this thread was going superconductive :-)
though even with 3mm contact separation, there's a vague possibility of flashover ;-)
