**very compact  size mould-proof housing** 

## **Area of Application** 

The temperature detector P is used wherever protection against overtemperature is required. Specific applications include: protection of primary windings in transformers, winding protection in small electric motors, and general temperature protection of small electric equipments. 

system and thereby interrupting the electric circuit of the device to be protected. 

After cooling down and reaching the closing temperature TE, the bimetal disk will automatically return into its original position and thus make the contact. The electric circuit is closed again.

**Configuration examples** 

## **Function** 

The temperature detector P operates independent from any current supply. Temperature detection is effected by means of a bimetal disk which was first dimensioned in accordance with the required cut-off temperature TA. When this fixed cut-off temperature TA is reached, this bimetal disk will snap over, breaking a contact

## **Technical Data** 

The housing of this switch consists of a single part bag housing which is closed at its end by resin (P8 housing type); this makes the switch mould-proof. This mouldproof switch may thus also be used in "tough" environments subject to the detrimental influences of humidity or dirt. Alternative housing types: unsealed version (P5) or plate bar version (P1). All housing types are voltage-free. Due to its constructional size the P switch is one of the most compact thermostats available. This ensures a very fast response rate. 

Its rectangular homogenous constructional size provides excellent thermal conduction characteristics. The housing is resistant against temperatures (permanent temperature: 160°C), with a temporary increase in temperature up to 200°C max. being permissible for a short period only. 

The standard version is equipped with 100 mm long (length of stripped isolation: 10 mm) insulated leads or wire connection (AWG 24). 

Special leads or wire (larger diameter to AWG 22) or different lengths available on request.
