Rittal Changeover Enclosure Thermostat, 24 V dc, 230 V ac, +5 → +55 °C

This high-performance thermostat from Rittal is used to control fans, air conditioning units and heat exchangers in wall boxes and enclosures. It can also be used to generate signals for internal temperature monitoring, making it a versatile choice. It uses a bi-metal sensory element to detect temperature changes in the enclosure, switching the fans on or off to keep the heat level within a stable range. The housing is made of a thermoplastic material, which provides impact resistance and excellent insulation for protection against electric shocks.
