- Certified safety — ±5% tolerance and RoHS compliance guarantee stable long-term operation
- Direct replacement — standard dimensions for quick retrofitting without modifications to the electrical installation
How it works and how to install
The capacitor stores electrical energy and releases it quickly when the motor starts, providing the extra power needed to overcome initial inertia. It connects in series with the motor's auxiliary winding via the 4 metal terminals — identify the terminals according to the equipment's electrical diagram, insert the spades onto the corresponding terminals, and secure the connections. Before installation, disconnect power and discharge the old capacitor with a resistor for maximum safety.
Frequently Asked Questions
How do I know if this capacitor is compatible with my motor?
Check the capacitance (3uF) and voltage (450V) written on the old capacitor — they must match exactly. The number of terminals (4) and the rectangular shape are additional indicators of compatibility.
Can it also work at voltages lower than 450V?
Yes, 450V is the maximum permissible voltage — the capacitor operates normally at 220-240V from the household mains, with a built-in safety margin.
How long does such a capacitor last on average?
Under normal use in household or industrial equipment, the lifespan exceeds 5-7 years. Premature deterioration usually occurs due to overvoltages or excessive temperatures.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
