Schneider Electric Monitoring Relay, 3 Phase, SPDT, DIN Rail, 480V ac

Description

RM17 UB3 and RM35 UB3 Three-Phase Voltage Control Relay

Schneider Electric RM17/35 UB measurement and control relays for 3 phase supplies, monitor correct sequences of phases L1, L2 and L3. It also monitors total loss of one or more phases, asymmetry, and over and undervoltage with independent adjustments. In the event of voltage fault, the relay opens at the end of the time delay set by the user, if the device is switched on with a measured fault, the relay remains open.
