Unipolar thermostat R 300 for water heaters
The R 300 unipolar thermostat is an essential device for temperature control in water heaters and hot water storage tanks. Thanks to the internal thermal sensor, it reliably regulates the switching on and off of the heating element, ensuring safety and energy saving.
Precise operation
The thermostat automatically intervenes to keep the water within safe and optimal temperatures. The switch-off point (T1) is set at 70°C ±5, while the switch-on point (T2) is at 60°C ±5, ensuring a stable and consistent heating cycle.
Reliable connection
Brass terminals with 4mm screws ensure a secure connection to the power supply. Plugging pressure between 4 and 15 Nw ensures stable contact, reducing risks of malfunction due to unstable connections.
Safety and robustness
The device is designed to operate in environments up to 105°C, withstand prolonged use and ensure the safety of the water heater's electrical system. The contact rating of 20 A at 250 V allows it to handle standard resistors with reliability.
Applications
Perfect for domestic and industrial water heaters, hot water storage tanks, and other electric heating systems that require precise temperature control with automatic intervention.
