632691R PTCR Case Type PTC Thermistors Switch MZ92D-40RN For Motor Starting Of Refrigerator Compressors Airconditioning systems
In the starting circuit of a single-phase AC motor, a PTC thermistor in series with an auxiliary starting coil is automatically disconnected after the motor is accelerated, thereby protecting the coil from damage. Various forms of the encapsulation housing may be provided.
* Single Phase motor start assist in
- Refrigerator compressors systems
- Airconditioning systems
- Heat-pumps
* Inrush current generation
* Household appliances (refrigerator, air conditioner, etc.), motor, train, heating room, dryer, other
1. High voltage resistance
2. Good impact resistance
3, long service life
4. Small residual current
5, low power
6. Good flame retardant performance
7. Metallization
8. Suitable for clamp contacting
9. High withstand voltage and inrush current
10. Various pellet sizes and curie temperature for optimum inrush current and switching time
