CARATTERISTICHE CHIAVE

Starter star-triangle

The star triangle starter is the best known and perhaps the most widely used of the low-voltage starter methods.

It is used to start the pump motor reducing mechanical stress and limiting currents during start-up, all through a timed system that allows the switching of the control contactors installed inside the panel.

Numbered cables

Extra Stardelta

The range of electrical control panels STARDELTA is proposed as standard with ABS plastic box up to 11 KW, for higher powers the box is metal.

A number of accessories are available to customize your picture and enrich it with more controls and functions.

Extra Stardelta

Benefits

The star start triangle reduces the current and the starting torque to 33% (1/3) of those found in a direct start.

During the start-up phase, the components are affected by currents below the rated motor current.
