Helping You Meet Customer Expectations Traditional telephone service has evolved to include broadband transmission of data, Internet access and other converged media. Customer expectations of 24/7 access, consistent quality-of-service and high reliability are now greater than ever before. In light of these developments, the need for circuit protection to ensure both successful day-to-day operation and public safety is also greater than ever. Today’s copper plant is exposed to threats from AC power fault and lightning induced events. Unless telecommunications links are properly protected, this...

Littelfuse-The Leader In Telecommunication Protection Serving Telecommunications Engineers with Teccor® Solutions Founded in 1964 as Electronic Controls Corporation, Teccor products included lighting controls and motor speed controls. To provide the highest quality product, Teccor began to design and make its own thyristors. Soon after, Teccor chose to concentrate on discrete thyristor components, leaving the manufacture of the assemblies to its customers. Circuit protection solutions from In 2003, Teccor was acquired by Littelfuse, Inc. and today lives on as the most recognized brand in telecom...
