SCR which can conduct 230V AC at Zero gate voltage
You could consider using a MOSFET-output SSR with normally-closed output (also called "Form B"). They conduct AC (or DC) and can be controlled from a microcontroller directly with a single resistor, and also include isolation. 

It's not clear to me what exactly your load is, but perhaps something like this which can switch up to 0.5A at 220VAC. Lower current capacity devices in smaller packages are available from various manufacturers.
