Vacuum Interrupters
Vacuum Interrupters
Feature
- Various types and ratings are available for circuit breakers, contactors and load break switches.
- Compact interrupters are accomplished according to the most suitable design on electrode.
- Low-surge characteristics are obtained with special contact material, it will last for many operations.
- The compact and lightweight mechanism will be realized due to the small contact stroke.
Safety
- The arc extinction is completed in vacuum, hence neither harmful byproduct will be produced, nor hazardous fire generated.
- The highest reliability and stable performances have been realized under history of three millions production.
Maintenance
- Less maintenance will be required since the contacts are sealed hermetically in envelope.
Environmental Consideration
- Neither harmful gases nor byproduct will be generated since the current breaking is performed in the hermetically sealed envelope.
- All the material and parts are designed under consideration of environmental protection.
