Elastimold Tru-Break Switchgear Module

Elastimold™ solid-dielectric medium voltage molded vacuum switches, interrupters and switchgear are available with the Tru-Break™ switchgear module — available in both single-phase and three-phase models. This visible-break device makes it easy for linemen to switch the handle to the open position and visually verify the isolating gap in the conducting path. This provides an added measure of confidence to utility company crews that the circuit is de-energized and it’s safe to begin their standard procedures for grounding before performing work on the line.

  • Safe — Dead-front construction with clear visual verification of circuit isolation. Positive-latching handle ensures that the unit is in a fully open or fully closed position. EPDM rubber eliminates the need for venting ports required with rigid epoxy constructions.
  • Reliable — Uses a proprietary EPDM rubber formulation, used in the field for over 50 years, on a solid-dielectric platform. Silicone diaphragm and air as an insulating medium. Contains no oil or gas for virtually maintenance-free operation.
  • Flexible — Rated for use with 15–29.3 kV, 630 A, 20 kA electrical distribution systems. Rugged and submersible for multiway pad-mount or vault applications. Compact size minimizes impact to switchgear footprint.


*Tru-Break switchgear module is considered maintenance-free because it contains no oil or gas to monitor or maintain.
