MOTOR PROTECTION THERMISTOR
|
| |
INSTA Motor Protection Thermistors are manufactured in accordance with DIN 44081 and 44082. Due to their small thermal mass, they have favorable temperature sensitivity.
INSTA Motor Protection Thermistors should be placed as near as possible to the hot spot: In three phase motors, one Thermistor should be embedded in each phase. Good thermal coupling between Thermistor and winding is essential. The PTC Thermistors should be inserted parallel to the winding. The resistance increases sharply in the region of the nominal response temperature.
In this way the mechanical stresses on the Thermistors during forming the end turns of overhang winding can be minimized. Shrink cap is especially well suited for this because of its mechanical stability. Response times ≤ 5 sec. are achieved with INSTA Motor Protection Thermistor. |
