fibaro 500w dimmer

Fuse box tripped halogen 50w bulb had reached end of life... Now dimmer is dead! Why?

My fusebox is not cheap its extremely sensitive so I'm gobsmacked if dimmer is cooked!

I had same issue with a vers 1.4. The bulb didn't reach it's end of life, but I got short circuit.

500W in 230V is 2A, but all light in France are on 10A fuse... So the fuse is the Fibaro dimmer.

As electronician, we says that the electronic, in general "protect" the fuse, since there is lots of example when the fuse is totaly intact, but not the electronic that the fuse should protect...

Am I entitled to a replacement?

I was mounting a ceiling lamp in the past, normally you won't switch off the power, you'd just make sure that the switch is off (I know this isn't according to any H&S-standards, but at home).

I just forgot that the Fibaro dimmer still sends a current over the line. Then the wires touched. Big bang from the dimmer, flash from the cables and all power out. After restoring power and mounting the lamp, it didn't work. Dimmer unreachable, not responding to the switch, none what so ever.

I got these instructions: Reset by holding B button for 3 sec. after connecting

mains voltage to the Dimmer. That brought my unit back to life.

Its dead 100% tried reset even with exclude and the manual method fibaro physically not detecting device. I had a spare so swapped it but my main concern is will this happen each time I have a 50w bulb blow?

Gets expensive bulb + dimmer each time!

If you connect dimmer to the bulb and push inclusion button on/off, nothing happens?

[deanrparry 19]

Correct no signs of life! the inclusion/internal button does not trigger the light at all!

Recently I've added a 2A "fast" glass fuse to all my dimmers. My dimmers are connected to halogen lamps ranging 60 - 300 Watt. I had one of the 300 W halogens blow, and the fuse had gone too. Did the fuse protect my dimmer? I must say that I doubt this setup protects against destroying a triac. I have seen it on classic style dimmers (niko) and I think it was meant to protect the dimmer against overload, not short circuit. For example, a customer could replace 2x200 Watt lamps by 2x300 which would be 100 Watt above spec (500W Fibaro dimmer) without realising this is an error. BTW there seems to be a "semiconductor" fuse that responds faster than "F" type fuses - but I have never seen one in my life

It would be nice to have a recommendation from Fibaro on this matter!
