About Thermik Gerätebau GmbH

Thermik Group – founded 1968 - is the global market leader in producing thermal protectors which protect electronic windings and applications. Operating with 4 factories located on 3 continents and with more than 40 international representatives Thermik ensures a worldwide supply of thermal protectors, thermistors, PTC heating elements, KTY sensors and motor starting units. Among all producers Thermik not only has the most extensive product range but also the utmost number of customized solutions.

Temperature limiters (CW1)

The thermal switch CW1 is used to protect transformers. It is recommended in all cases of an increase in temperature, due to an overload current, e.g. in case of short circuit and where resetting is n...

Temperature limiters (C06)

The switch C06 – without insulation cap - is characterized by its ability to tolerate high current load in spite of its small design. Furthermore it can be installed into windings because it is resist...

Temperature Sensor (S06)

The switch S06 – with insulation cap - is characterized by its ability to tolerate high current load in spite of its small design. Furthermore it can be installed into windings because it is resistan...

Temperature limiters (V06)

This switch is designed for thermal protection of electrical devices if protection class II is required. The Ryton housing with a dielectric strength of 3750 V allows fastening to the object to be pro...

Temperature Monitor (P08)

Thermal Protector P08

Power class: 4,0 A to 25,0 A
Type series: 08
  • normally open
  • resets automatically
  • with connection pins
  • fully insula...

PTC Motor Protector (STM)

This PTC motor protector can be used in various ways, e.g. motors, transformers. It is characterized by reliability and form stability. Because of its small construction it is also usable in difficult...

PTC Thermistor

General areas of application

PTC thermistors are heat-sensitive sensors whose resistance increases with temperature, and can be used in almost all areas where a digital temperature measurem...

Temperature Monitoring (Termistores-PTC LTM)

Where possible, the PTCs are to be inserted parallel to the coil. As a result, when shaping the coil ends, the mechanical stress of the PTCs is minimised. In so doing, the Mylar®-­Nomex&reg...

Electronic components

All Thermik products are state of the art in terms of design, material selection and composition and are protected by numerous national and international industrial property rights. Thermik's self-...

Temperature sensors

In order to measure and control the temperature in various electronic devices (temperature protection) as part of temperature protection, we use the properties of bimetals in our temperature limite...

Thermal Protection Devices

  • Round thermal protectors
  • Flat thermal protectors
  • Pressure-resistant thermal protectors
  • Sealed thermal protectors
  • Current-independent thermal protector...

Bimetallic Switch

Bimetal discs are subject to an ageing process that cannot be avoided. This changes the function parameters of the discs, depending on their load capacity and life cycle. The parametric stability o...
