Delta old key for Jumbo 651 machine

The Delta-Star machine switch Jumbo 651 is a manual cam switch designed for starting three-phase electric motors in the "star-delta" circuit. This type of start allows for smooth machine start-up, significantly reducing the starting current and protecting the electrical network from overload.

The switch is mainly used in building material saws, such as the Jumbo 651 model, equipped with a powerful electric motor. With its three positions - off, star and delta - it ensures safe starting and normal operation at full power.
