PVT: Three Phase Voltage Relay (Microprocessor)

15 Amp Contacts

600V Contact (Available)

Dual Voltage Model

Removeable Terminal Blocks

Over & Undervoltage

Phase Loss

Phase Imbalance

Phase Rotation

Adj. Re-Start Timer

Operation

The PVT’s output contacts are energized when: 1. All phases are present, 2. Voltages are within differential %, 3. Phases are in the proper rotation, 4. Phases are balanced, and 5. Re-Start timer has timed out. The PVT uses a re-start timer to allow the three phase line to stablize after a fault and delays re-starting of pumps, compressors and other equipment. The PVT also has a switch selectable voltage option (Series 201) that provides both 208 to 240VAC and 420 to 480VAC, 3Ø in one unit. The installer to select the proper voltage.
