VST120 SERIES
SNAPTRACK™ 20A
SPDT Relays
VERIS INDUSTRIES
VS T12 0
Space Saving Open Style Relays
DESCRIPTION
The VST120 Series track mount industrial-strength relays will easily mount to either
2.75” or 4” SNAPTRACK™. The space-saving design allows you to t many relays
in a single electrical box for easy installation and servicing. These devices include
convenience-adding features, such as an LED for status indication and an HOA switch
for local control (see ordering table for models with HOA switches).
APPLICATIONS
● Lighting panels
● Control motors
● Isolation
● Device interlocking
RELAYS
VS T12 0-4
FEATURES
● Relay logic
● Sense voltages for alarm conditions
● Mount relay right in panel to save installation time and space on the jobsite
