How do I trigger it from a microcontroller?
Do not connect the gate directly to a microcontroller pin in mains circuits. Use an opto-isolated triac driver, such as an MOC3021-series device, with a series gate resistor, and confirm values in the datasheet.
Can it switch mains loads?
Its 500 V rating allows use on 230 V AC circuits, but mains work requires a proper enclosure, isolation and protection. Inductive loads such as motors usually need a snubber. Only work with mains if you are qualified.
