450V 100µF Motor Start Capacitor for Industrial Equipment
This start capacitor ensures the reliable operation of single-phase motors in industrial and domestic equipment. With a capacity of 100µF and a rated voltage of 450V AC, it is the professional solution for pumps, compressors, fans, and air conditioning systems. Compact cylindrical design with wire connections, easy to integrate into any existing installation.
What you get with this product
- Fast and safe starting of single-phase motors, without interruptions or false contacts
- Universal compatibility with most 450V motors in compressors, pumps, and fans
- Flexible installation via direct wire connection, without the need for additional supports
- Extended lifespan of up to 10,000 hours at 400V, with self-healing technology
- Stable operation in extreme conditions, from -40°C to +85°C
- Encapsulated construction in resistant plastic, with short-circuit and overvoltage protection
How it works and how to install it
The capacitor is mounted in series with the starting coil of the single-phase electric motor, creating the necessary phase shift for starting. Connection is made via the two wires, observing the polarity indicated on the casing. Secure the capacitor in a stable position, protected from heat sources and excessive humidity. After connection, the motor starts instantly and operates at normal parameters.
Frequently Asked Questions
Can I use this capacitor for my air conditioner compressor motor?
Yes, it is compatible with air conditioner compressors, refrigerators, and fridge-freezers that operate at 450V and require a 100µF capacity.
What does a tolerance of +/-5% capacity mean?
It means that the actual value can vary between 95µF and 105µF, a normal deviation that does not affect motor operation.
Does it withstand high temperatures in summer?
Yes, it is designed for continuous operation between -40°C and +85°C, covering all climatic conditions in Romania.
