The AMS 7001 is usually used in automatic changeover and transfer schemes as it can simultaneously control two circuit breakers and monitor two voltages.
The AMS 7002 can be used where switchboards include supervision / control, metering and instrumentation, and/or automatic local control such as motor restart sequences using real time voltage monitoring.
