I have a bunch of electro-mechanical relays on a board intended to switch 220VAC for CFLs. The maximum load on the relays will be 100W with inrush currents of upto 2A (lasting for less than a second). The relays do survive short-circuit currents, briefly, as long as a 10A circuit-breaker kicks in.
The relays is Omrom G5LE-1A DC5 - a 240VAC 1200VA relay. I am also considering the G5LE-1A-E-DC5 which is the 16A version of the above relay with 4000VA switching power - link to datasheet.
My question is, is it safe to rely on this for a commercial product? We won't be installing this anywhere that does not have a proper breaker system anyway. I don't want to include a fuse for two reasons:
The product is intended to be mounted on a wall. The board will not be easily accessible.
The board has live voltages and if possible, I would prefer that the user does not have to replace the fuse very often, unless there is catastrophic failure like the circuit-breaker failing as well. I'm not counting a short-circuit as a catastrophic failure because some (poorly made) CFLs end up failing as a short-circuit and this could be a annual occurrence or more frequent - the user would probably get fed up of the product.
I think some sort of backup protection should be there but resettable fuses seem to be too slow, at least for mains voltages. What are my options here?
