VACUUM SWITCH TECHNOLOGY WITH SELF-LEARNING FIRMWARE
Breathers have a long history and serve a critical role in the health of a transformer. First generation breathers required routine replacement of silica gel to provide dry air, increasing maintenance expense. Next generation breather design provided silica gel regeneration, using heat to dry out the silica. The challenge then is to prevent freebreathing during regeneration, which could introduce moist air into the transformer or LTC oil.

SINGLE COLUMN BREATHER FEATURES
Construction
• Sealed/Latching solenoid for improved reliability
• Aluminum and stainless steel construction for durability
• Borosilicate glass globes resist weather-related etching
• Sealed, super bright 10,000 mcd LED indicators on control box provide easy visual indication of breather status, even in
direct sunlight Performance
• Time-based regeneration settings included Convenience
• Standard alarm contacts for remote alerts
• Adapter plate enables easy upgrade from ARDB2
• Conduit wiring does not require adapter box
• Silica gel ships installed
ARCTIC BREATHER
• Fully functional between–50°C and 80°C
• From –50°C to 0°C, the heated filter vent prevents freezing of water generated from the regeneration process, allowing complete drainage
• Applies to breather models SCB-A01 & SCB-A11 on the configurator above.
