The electrical panels with star/delta starting are designed and manufactured in compliance with current regulations for the control of medium and large power motors, starting from the size of 5.5kW (inclusive) and up. This starting system makes it possible to overcome problems of excessive absorption during the starting phase, as the motors are initially started via a star connection, reducing the initial current consumption, and then switch to a delta connection when the engine is brought up to speed, all via a timed system that allows the switching of the control contactors installed inside the panel.
Each panel has lights indicating the presence of voltage, thermal intervention and engine running, as well as the engine start and stop button and the mushroom-shaped emergency stop button.
Everything is contained in a painted sheet metal box with wall fixing brackets, disconnect switch with door lock system for powering the panel and lock for closing the door.
Interfacing with the users is carried out via the terminal block positioned in the lower part of the panel, where, in addition to the terminals for powering the motor, also those for possible interfacing with a start/stop and stop button panel are made available. remote emergency.
The supply also includes the electrical diagrams, created in compliance with current regulations, and the Declaration of Conformity.
On request, various options can be integrated, including ammeter for displaying the absorbed current, hour counter for counting the motor's working hours and cable glands for the entry of the cables of the utilities to be managed, as well as various possibilities for customization , depending on the customer's needs.
