## Questions & Answers

**Q: Can this be used to shut off a 12 volt DC linear actuator if it gets jammed?**
A: No.  A CT cannot be used to measure DC amps.

**Q: Will this work with 24v on the switch leg with 120v 10 amp motor in the CT?**
A: Your question doesn't include the main ingredient. As far as I know, it's the current through the switch that will cause failure. I avoided the problem by using a relay to handle the load. I hope this helps.

**Q: Can i switch a 20 watt ac (led or cfl) on/off using the"k1,k2" contacts? it works, but for how long- design for it? k1,k2= solid state relay/mosfet.**
A: The k1, k2 contacts aren't rated for much of a load. To be on the safe side, I used the contacts to power a small relay and let the relay handle the load.

**Q: I concerned about the switch toggling off-on-off repeating.  does this unit have a switch on/off delay, I'd like about 5 minutes of delay**
A: It doesn't have a lockout or a time delay, it's on or off. I haven't had a problem with it kicking on and off. The application I'm using it for is a pump on a sand filter reading that amps to know if and when it looses its prime, to turn a light on to get people's attention.
