PR200 Digital Motor Protection Relay

PR200 Digital Motor Protection Relay

The PR200 Digital Motor Protection Relay monitors 3-phase power lines for abnormalities. This 3-phase motor protection relay can be used with motors less than 690V/820A. It can be packed inside a small and economical package so this motor protection relay can save you time and money.

Startup mode: protected mode
Protection functions: overload, phase failure, blockage, unbalance, timeout, underload, leakage, Undervoltage, overvoltage
Relay output: programmable 1-2 channels of DO
Display mode: LED display
Measurement parameters: 3I, 3U
