Vacuum Contact Module
The Watteredge Vacuum Contact Switch equiped of the patented DC Vacuum Contact Module, provides a high current DC shorting switch which offers safety, reliability and long life. The switch provides superior performance in the harsh environments of electrolytic cell applications, particularly in chlor-alkali and metals refining processes.
The contact can be purchased for integration into your switching project or you can purchase a complete switch unit as shown on our fixed and portable switch product pages.
Overall maintenance and energy costs are significantly reduced when patented Watteredge Vacuum Contact Switches are substituted for conventional contact switches. Further savings result from the elimination of lost production time due to emergency shutdowns or reductions in cell current caused by partial or complete failure of conventional contact switches.
Watteredge Vacuum Contact Modules provide a wide range of operating benefits, including:
- Longer life than any other configuration available.
- Absence of contact corrosion, offering consistently low contact resistance.
- No organic seals - the manufacturing process uses high-temperature brazed joints.
- Elimination of entrapment of foreign material between the contacts.
- Absence of exposed arcing and flying hot metal.
- Operation at higher ambient temperatures without harm to contacts.
- Increased facility productivity through near-elimination of downtime or reduced current operation due to faulty switches.
