Over half a century

at the forefront

of electrotechnical production.
COET S.r.l. was founded in 1962. During almost half a century of history the company has been growing and evolving designing and manufacturing various types of switching and sectionalising devices and the switchgears and systems that utilise such devices.

At present COET’s production includes different ranges of products for various applications:

  • Switching and Disconnecting devices for Low Voltage.
  • Switching and Disconnecting devices for Medium Voltage.
  • Switching and Disconnecting devices for High Current.
  • DC Switching and Disconnecting devices for Electric Traction.
  • Electronic measuring and monitoring devices.
  • Electric Traction Power Systems.
  • Engineering

Conceiving and Design of products is totally self made with the support of the most up-to-date computerised systems of Electrical and Mechanical 3D CAD.
The Test Laboratory can perform functional and mechanical Endurance Tests, Temperature rise Tests with current up to 10.000A and Dielectric Tests with voltage up to 60kVrms and 400kV impulse using high precision measuring and recording instruments.

Since 1998 the company is certified ISO9001 and ISO14001 and all the products are type tested according to the latest International Standards.
The headquarter that includes offices, workshop and test laboratories for high current and high voltage, is located in San Donato Milanese, nowadays part of Milano, 10km from the city centre as well as from Linate Airport, adjacent to motorway city ring and close to the railway’s freight yard:

Total Area: 9000 sqm
Covered Area: 4900sqm
Offices: 600sqm
