Low voltage distribution boards and motor control center

Already in former years, “Sprecher” had been associated with high-quality and absolutely reliable low voltage switchgear solutions. Since decades, Sprecher Automation has been developing LV switchgears and distribution boards for auxiliary services in power utilities as well as for power supply and distribution in various industries.

Sprecher LV switchgears guarantee easy expandability of existing equipment whereas expenditures are limited by the actual system extensions. The various switchgear models are based on a modular and flexible component system.

Project management, detailed and overall planning, assembling, installation and final tests are all accomplished by Sprecher Automation. Beside of turnkey systems, Sprecher also offers on-site installation, commissioning as well as maintenance and service works.
