VR-300 Multifunctional Voltage Relay
Product Description
The VR-300 is an industrial
grade protective relay that
offers multiple protective
features in a single package,
ideal for standalone protection
or for the
implementation of
transfer schemes.
Using a digital processor to
measure true rms values
enables a high degree of
measuring accuracy
regardless of harmonics,
transients or disturbing
pulses.
The compact size and
multiple functions of the
VR-300 help to simplify
switchgear design. The digital
display offers a user-friendly
interface to set up the unit as
well as monitor the operation
and display any alarms.
