A Sonepar Company
Home > Ilsco


ILSCO was originally known as the Incandescent Light and Stove Co., but today we make neither lights nor stoves. We are now known as a leader in the industry for our mechanical and compression connectors, with people in eight different locations across three countries.  ILSCO is a privately held, third-generation, family-owned, U.S. manufacturer of electrical connectors that celebrated 120 years of service in 2014. The recent acquisition of Surge Suppression Incorporated (SSI), a pre-eminent supplier of surge-protection devices, positions ILSCO to provide more complete solutions to customers’ electrical needs.

ILSCO’s manufacturing expertise extends to:

  • High-volume, state-of-the-art, proprietary manufacturing processes
  • Copper and aluminum manufacturing
  • ISO 9001:2008
  • Vertically integrated
    • Aluminum extrusion
    • Screws
    • Plating
  • RoHS/REACH–compliant materials and processes

More than a connector company, ILSCO is a connections company. Connections Matter.
