Vacuum contactors provide all the operating advantages of a vacuum interrupter plus the benefits of a matching actuator to meet specific application requirements. These low and medium voltage contactors offer the most reliable means of remotely controlling electric power.
Jennings vacuum contactors
Jennings contactors consist of a vacuum interrupter and an actuator linked together by an insulated actuating rod. Linkage and stand-off posts that isolate the high voltage from the ground are made of epoxy glass laminate for DC switching. Heavy duty connectors are provided for the high voltage connection.
- No required contact maintenance
- Long life
- Environmental safety factor
- Compact, reliable operating mechanism
- No arc chute replacement which vacuum contactors operate causes the arc to be extinguished rapidly with minimal damage or wear.
- Proven operation
- Low contact resistance
