JUMO heatTHERM P300
3-phase panel-mounted thermostat
The 3-phase JUMO heatTHERM P300 can switch outputs up to 480 V at 30 A. All phases are disconnected from the power grid simultaneously here. The device is a safety temperature limiter (STB) and sets the system being monitored to a safe operating status in the event of a malfunction.
