Controls

Smart, Light and Flexible

The Elastimold ® Recloser is world-class, by design. It responds to every hardware requirement that utilities want.

Smart – Our recloser is Smart Grid ready with three integral load-side voltage sensors and provision to add source-side voltage sensors, if desired. It was designed to be fully compatible with the industry’s

No. 1 name in controls, Schweitzer Engineering Laboratories.

Light – The three-phase Elastimold ® Recloser weighs 33% less than existing typical units. The simplicity of the mechanism design, and the compactness of the encapsulated components, contribute to making the

Elastimold ® Recloser easier to move and install.

Flexible – The Elastimold ® Recloser is modular, so field upgrades and retrofits are easy and fast. The single phase recloser has a pole rotation mounting bracket for easier installation.

Made with Your Needs in Mind – We designed the Elastimold ® Recloser only after extensive talks with electric utilities. Its features, from easier-to-see open/close indicators to the many robust extra features that we consider “standard”, are there because of you.

Recloser Operation

The Elastimold ® Molded Vacuum Recloser (MVR) operates electrically by energizing a magnetic actuator system with a completely sealed housing. Each pole contains a vacuum interrupter sealed in solid dielectric insulation for mechanical and high dielectric strength.

An open-closed position indicator provides a 360-degree view. An external manual trip assembly is located on the side; when in the down position, it maintains the recloser in a lockout position until it is manually restored. All electrical control connections are made through a sealed single-environment control cable connector on the side.

The combination of the molded vacuum recloser with microprocessor controls accurately detects a wide range of line disturbances and provides reliable, high-speed isolation for adverse conditions.
