Your cart is empty. SZC23 series AC current sensing switch is designed and manufactured to
solve the AC current monitoring. It uses the principle of mutual
inductance to sense the AC straight through current, isolate the AC
current, and output a normally open or normally closed switching signal
to directly control various automation industrial equipment, such as
flash, buzzer, relay, single chip or other power load equipment.
Compared with traditional mutual inductors, thermal protectors and other
devices, using this device can not only get more accurate and more
timely control, but can also greatly simplify the design and reduce
costs.

Used to turn on a 120V outlet that supplied a simple 6" AC duct booster fan. Unit worked less than a day until it was found melted as shown. Definitely not a 30A switch nor can it be used for the applications stated.

I used this to lower my motorized projection screen when i turn on the projector. Have the power wire running through this, when I turn on the projector screen goes down. Sensitive enough that when the projector goes into standby mode, the lower power draw is enough to raise the screen for me.
