Paul, What you want is a circuit breaker with a shunt trip coil. Apply voltage to the coil and the breaker moves to the tripped / off position. They are available in 12, 24, 48VDC, and 120 VAC. There is no static power loss from this (unlike a relay that is electrically held in the on position) If the site has a phone patch, you can use the phone line to accept a DTMF string to operate the "power off" command. Otherwise, you are stuck with in-band management (DTMF and PL)
