Circuit breaker for glass cook top
You don't ever change the breakers to match the appliance !!
You can only change the breakers after you upgraded the wires to carry the needed load.
I have an induction cooktop, and I needed to upgrade the wires to a bigger gauge. Luckily, it was just 6 feet. Costly, but that's the only way.
If you change the breakers but not the wires, your wires will overheat and your house burn down. The insurance company will find this post :-).
More seriously, upgrade the wires first(1), then up the breakers, then enjoy your cooking.
Edit:
(1) More precisely, make sure they are the proper gauge. There's some subtlety there. The run-of-the-mill 8-gauge solid copper as sold in my area is good for 40amps. But I have no clue what type of wires you have in your area.
