The RC30 Capillary Hot Water Thermostat (50-83 °C, 850 mm) is a temperature control device designed for domestic water heating systems. It detects and regulates water temperature using a long capillary sensing bulb, shutting off power when the water rises above the set range.

  • Adjustable temperature range: 50-83 °C, suited to many domestic water heater setups. 

  • Long 850 mm capillary sensor for accurate temperature sensing from a distance. 

  • Break on temperature rise – ensures safety by cutting off when set temperature exceeded.

  • 16 A, 240 V rating – compatible with typical household circuits. 

  • Robust bulb design: 6.5 mm bulb diameter / 100 mm bulb length, with 550 mm copper capillary tubing. 

  • Equivalent to models NT-122 IV, EGO:55.13012.740
