Hi All

I need some surgestions for a overload protection circuit. I have this piece of schematic, and need some ideas on how to make a circuitm, which will turn off (relay) if the effect in the circuit is above 2kW.

if you can ensure that neither voltage nor current do not exceed limits, you are ok. just google for "overload relay", click on Images to see what they look like:

as you can see they mount right into a contactor (which is type of relay).
note that overload relays have little dial so you can set trip current.

this is how overload looks like

SMD? after you put relay for 10Amp, 230VAC circuit???
well anyway, the idea is to trip circuit when current exceeds
certain limit. this can be done in number of different ways.
for SMD solution check Allegro's line of product. Here is one
