One of the things we are more proud of is that we internally design and produce our low-voltage electric switchboards: a key element in any electric and mechanic installation.
This choice allowed us to create Customized solutions for low-voltage electric cabinets:
The Electric Switchboard Division was born in the 80s from the acquisition of Mazzilli and C. SpA, which was then incorporated in 2006 in Elettromeccanica Galli Italo SpA.
Our products are the result of the constant research and development of our electric cabinet department, that constantly develops and fine-tunes new solutions thanks to the collaboration and suggestions of the technical engineering sector.
Certifications
Anti-seismic Certification
The Electrical Switchboards Division has obtained for the following products
- Power Center series "GIOVE-120"
- Secondary distribution Electrical Panel "SATURNO-AS"
anti-seismic certification (ref. IEC standard EN 60068-3-3 and International Standard IEEE693).
The tests took place at the CESI – LPS laboratory in Seriate (Structural Testing Laboratory P610) accredited in accordance with EN ISO/IEC 17025: 2005 by ACCREDIA (LAB 0030; Seat C) for the execution of "Vibration tests with random dynamic forces – Method with oscillogram" in accordance with IEC En 60068-2-57: 2014 (par. 8.1, 8.2, 8.3, 8.5) / IEC 60068-2-57: 2013 (par. 8.1, 8.2, 8.3, 8.5)
The units were subjected to tests aimed at the analysis of structural resistance to the earthquake; the activities included resonance frequency research tests and tests with multifrequential triaxial vibration of a seismic type.
Resonance frequency research tests
The purpose of these tests is to determine the resonance frequencies of the Units (in the field of seismic frequencies) and to evaluate their structural damping at the lowest frequency:
| Type of test | Sine scans |
| Frequency field | 0.5 – 50 Hz |
| Stress level | 1 g (1 g = 9,81 m/s²) limiting the movement to ± 50 mm |
| Scanning speed | 0.5 Oct/min. |
| Directions | X, Y, Z (three mutually perpendicular axes of units, not simultaneously) |
| Number of scans | 1 (UP) |
Earthquake resistance tests
| Type of test | Multifrequency triaxial vibration |
| Frequency field | 1.5 (approx) – 50 Hz |
| Damping | 5% |
| ZPA | 1.0 g (note: 1 g corresponds to the highest possible level for IEEE693) |
| Directions | Three mutually perpendicular axes of units (simultaneously) |
| Number of pulses | ≤ 3 |
| Pulse duration | 32 seconds (strong part ≥ 20 sec.) |
The tests were carried out using:
- MASTER vibrating table (4x4 m: 6 dof) with digital data control and acquisition system;
- 24 acceleration transducers divided into triaxial accelerometric positions on units.

With this Certification, Elettromeccanica Galli Italo S.p.A. Electrical Switchboards Division proudly completes all the certifications required by the various Regulations, offering the market from low voltage products of excellence born from its professional experience gained in years of studies and research in the field of low voltage panels.
Low-voltage electric cabinets
GIOVE 120
Power Center
It is made of totally standardized sections and allows to apply any international normative solution.
Its electrical and mechanical characteristics and its compact dimensions make it a product suitable for any kind of application where a medium-high power distribution system is required.
Besides having a certified 120 kA short circuit current, can also be produced to withstand an internal arc seal up to 75 kA Icc.
