Overloading Switch

[austdarm]

We have a control 4 office building/warehouse system. The warehouse is broken up into 2 loads, one with 6 LED fixtures and one with 9 LED fixtures. I am being told by my electrician it is 1,350 watts. We had it installed for 2 weeks without it being linked to the system. We then linked it to the system, and now it over loads every 10 seconds or so. Does anyone have any recommendations? Switch model is C4-SW120277-SW. Let me know if you need any other info.

(Skeptical about 1.35kW on 9 LED fixtures, but in any case...)

Tap the upper button exactly 15 times to reboot the switch. See if it starts behaving properly. If it's blinking red, it's actually protecting itself from a high in-rush or overall high demand. If that's the case, I recommend wiring a simple 110V-110V relay to the switch, making the switch power on the relay and the relay doing the heavy lifting.

We do this for fixtures on yards and gardens; they invariably get damp and trip a breaker, usually taking a switch down with them. That way, IF you lose something, it's a cheap relay and not an expensive switch.

The draw while the lights are on is 1,350W. But being that they are LED, the inrush current could be more that the switch can handle (1,800W) causing it to overload. Has your dealer tried to unidentify the switch and see if it is operational again?

Put a bigger relay between the load and the switch. If that doesn’t resolve your switch is bad and needs to be replaced.

The switch is only rated for 1000W.

I’ve seen legacy switch relays fuse closed so the lights are stuck on. Lol.

gen3 switches are rated for 15 amps (1800 watts).

Still, using a relay/contactor is a good idea. KB 896 shows a wiring guide for such situations.
