install a 2 pole switch for a water heater

I installed a 30 amp switch so I could turn the water heater off when I didn't need it but the breaker trips when I flip it on. According to the instructions on the package I have wired it correctly. What would cause this. Kevin

What would cause this is not having it wired correctly or a defective water heater.
Give us some details and maybe we can help.
Start by disconnecting the heater cable and see if the breaker still trips.

I agree with Joed. Can you tell us the type of switch you bought; single pole, double pole,?
Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

you probably hooked the switch up wrong, so that the two hots connect together when you turn it on, creating a dead short

I am with others what type of switch it have and if you know the model number just post it here we will go from there and some disconnection switch it is too easy to transponed between the line and load connections.

That item I have see it pretty often when someone not pay attetion with it.

Wrong hookup or you have a 4-way switch instead of a 2-pole switch.
