Contact the major meter manufacturers. Most of them are now offering remote disconnect in their automated meters.
Wireless two-way communication allows the utility to disconnect customers for non-payment and then restore service all from the office.
The relay used in the device is rated to interrupt the full capacity of a residential meter.

you probably want a 'safety relay'.
To disconnect a large load is going to require a contactor.
Reliability is tricky. Just how reliable is 'very'???
