Make Switches play an essential role within power laboratories intended to test and certify electrical equipment through their ability to establish short circuits at the desired point of the electrical wave. Until now, most of the Make Switches have been placed in the primary circuit of the facility between the generator and the transformer, with […]
A global supplier of Circuit Breaker components, Etna-Industrie is proud of its success in Russia, where our presence dates back to 2007, uninterrupted by changes in the economic and political situation.

State Grid Electric Power Research Institute, one of the most prestigious player of Electrical Power Grid in China, is expanding its testing capability network. ETNA is accompanying its growth by supplying user friendly, up to date design 52 kV Make Switch, as part of global investment realized in Changzhou. The 52 kV Make Switch has […]
Stop talking about SHUNTS – Let’s speak about CVR (Current Viewing Resistors) CVR‘s are rugged high frequency resistors designed to sustain the very high peak power and current inputs generated by capacitor banks, pulse generator systems, and steady state current loads. Their linear response over a broad band pass provides an accurate indication of current […]
A safety valve is a device designed to protect equipment under pressure from exposure to overpressure, i.e. in excess of the maximum admissible.
The pressure safety valve may also be termed, less accurately, a pressure relief valve.
ETNA Industrie designs and manufactures pneumatic and hydraulic solutions for numerous applications including the regulation of fluids.
If the name itself is disconcerting, the worldwide famous product is also complex. Since 1966, Make switch answered specific requirements of high power or high Voltage type test laboratories. Make Switch’s mission : create a short-circuit Electric laboratories aim at testing and certifying high voltage or high power electronic devices (circuit breakers, transformers, specific components…).
