RLSwitcher® 38kV-72.5kV Catalog Flyer

Product catalog summary

Overview
The RLSwitcher® is a reactor switching device designed for use in electrical systems with voltage ratings between 38 kV and 72.5 kV. It is engineered to switch reactors with confidence and certainty, minimizing the risk of re-ignitions that can damage the system and reduce the lifespan of the reactor and switching device.

Benefits

Patented interrupter design reduces the probability and magnitude of re-ignitions.
Decreases turn-to-turn voltage stress on reactor windings.
Simplified and compact design enhances reliability and allows installation in tight spaces.
Equipped with local and remote gas monitoring systems.
