Find out what the RT 8804 capillary thermostat has to offer

The RT 8804 capillary thermostat is a single-pole temperature controller operating on the principle of liquid expansion, designed for precise temperature control in appliances with AC power supply, such as electric ovens. The device’s design is based on a switching unit and a capillary temperature sensor. Installation is carried out using two M4 screws, and the flexible capillary tube allows the sensor position to be freely adjusted to the requirements of the specific installation. The switching unit can be installed in any position, which increases design flexibility. The RT 8804 thermostat is intended for installation exclusively in Class I appliances equipped with connection terminals under a non-removable cover. The device is VDE-certified, confirming compliance with safety requirements. The product must not be used as a circuit breaker. By using the RT 8804 capillary thermostat, you gain:

Precise temperature control within a range of 50 to 320°C

High durability thanks to a service life of up to 100,000 operating cycles

Flexible installation thanks to the ability to position the switching unit as required

Easy to fit into the system thanks to the ability to bend the capillary tube with a min. capillary tube bending radius of 5 mm

Reliable operation without consuming electricity

Low operating and maintenance costs

Safety of use confirmed by VDE certification
