Y89-L-90-05-B08-170-6HA Limitor
Area of Application
The current and temperature limiter Y is used wherever, on one hand, protection against overtemperatures as well as against overcurrents is required, and, on the other hand,
automatic reset function of the device to be protected - subsequent to a follow-on cooling down period - is undesirable or not permissible.
Function
The current and temperature limiter Y operates dependent on any current supply.Temperaturedetection is effected by means of a bimetal disk which was first
dimensioned in accordance with the required cut-off temperature.
When this fixed cut-off temperature TA is reached, this bimetal disk will snap over, breaking a contact system and thereby interrupting the electric circuit of the device to
be protected.
Current sensitivity
If - the current increase to the double or more (for example: blocking current or short-circuit current), an additional resistor inside the limiter heats the bimetal
