CIRCUIT BREAKERS SWITCHING OFF STARTING CAPACITORS
Relays - circuit breakers are the most reliable devices for disconnecting starting capacitors from the electric motor circuit.
There are 2 types of Circuit breakers: electromechanical and electronic:
- Electromechanical relays are cheaper solution, suitable for motors whit not higher activation frequency, otherwise, there is a risk of the terminals sticking.
- Electronic relays allow a much higher number of switches per minute and are suitable for crane motors.
