Under operation it says it will shut off if there is a surge and device must be replace. Is this correct
The diagnostics LED indicator light is ON continuously when protection is active, but turns OFF when protection circuit is deactivated due to excessive transients. The entire unit must be replaced if surge protection is required. If the unit is not replaced, it will function only as a conventional receptacle within its given rating.
Would afci breakers be a good idea. The building is older and I doubt they will pay for pigtaling . Or afci outlets? Kinda pricey. 28.00An SPD will not help against bad voltages which are solidly fed and will continue to deliver energy to your loads even when the SPD tries to clamp those voltages.
Nor will they protect against voltage combinations that are within the range they have to withstand, e.g. still only 120V to ground even though the neutral went hot.
A line to "neutral" wired SPD might have pulled enough current to trip the branch breaker, but it is not designed to do that.
The lost neutral would have been prevented by current NEC compliant wiring (pigtailed neutral) in the receptacle box.

AFCI, breaker or receptacle, will not help for a bad neutral.
Chances are your mentioned arc at making/breaking of the circuit will not be long enough duration and/or at high enough current level to make the AFCI trip ........ unless it is a normal characteristic of a desired load, then it will always trip:roll:It wouldnt detect the neutral being disconnected . When theres a load on a neutrL it will arc if its pulled apart or when put together..
I dont know afci outlets that well. Thats why im asking.
