This thermostat functions as maintaining adjusted temperature by measuring external and internal temperature of the equipments as an expanding-liquid thermostat. If the sensor detects the heat, the liquid expands and it extends the space of diaphragm, and that power enables making and breaking contact points of the switch. It is an automatic reset product that repeats going up and down within the range of adjusted temperature.


RNTS-200 is designed to use up to double amounts (30A), compared to ordinary thermostats, so you can use this product without using separate relay or magnet switch when using high ampere electric heater.
