Frequently Asked Questions
What is the difference between ALV 10 (switch) and ALV 2 / M (start-up system)?
The ALV 10 is a protective circuit breaker — it interrupts the circuit in case of overload or short circuit, protecting the motor from damage. The ALV 2 / M is a star-delta start-up system (or soft start-up) for three-phase motors: it reduces the inrush current at start-up from 600–800% to 200–300% of the nominal current, preventing damage to the grid and the motor. The two components often work in tandem.
Are these components compatible with all Bernardo motors?
Each Bernardo electrical component is designed for specific models. Check compatibility with your machine model before purchasing. For confirmation, contact Krollit. Customer service available in Italian.
Are spare parts available?
Original spare parts available with 3–5 business day shipping. Customer service available in Italian.
