Normally kilns are 40 amp apiece. If you want remote disconnect means for each kiln, I'd put a non fused disconnect adjacent to each kiln. The kilns operate on 240 single phase. sometimes a kiln uses a timer for firing the "bisque." The timer is rated at 240 volts 40 amp with a 240 volt timer motor. Your primary overload device is the 40 amp 2 pole breaker feeding the circuit. Look at the nameplate and find out what the current draw is for each kiln and get back to us.
